How is HOPS / Boxcutter progressing for Blender 2.8?

It is in progress.


What is the difference between Hard Ops and Boxcutter?

Hard Ops is a toolkit containing many tools for various tasks ranging from viewport adjustment, rendering, helpers and symmetrization and not to mention sharpening.

Boxcutter is only a cutter. It only cuts. The purpose of boxcutter is to cut via drawing.

One can't replace the other. They are supplemental to each other. Boxcutter is a small subtool when compared to the entirety of the hops suite.


What is the difference between Hard Ops and KitOps?

Hard Ops is a toolkit containing many tools for assisting users with getting all the way from cube to final result. It's our swiss army knife of modelling. However back in 2016 I did discuss the implementation and our plans with it.

A few things to note. - I took the idea for Insert Merging from Chipp in Moi and I left a comment about it. - now he's using Blender years later and we collaborated to make his system from Moi a thing in Blender but faster - the initial insert system of HOPS was just a means to an end. It was limited due to its simplicity which limited our expansion on it. One mesh merged and one mesh left behind.

KitOps is focused primarily on insert management into packs called Kpacks and the workflows of aligning them on surfaces and smart behaviors. This takes the behavior system of subsets and removes several steps and makes it an artistic process compared to before.

What can KitOps do that Hard Ops doesn't?

  • manage inserts / allows for user created inserts
  • merge multiple levels of booleans in order
  • connection / disconnection live via smart selector
  • thumbnail rendering and creation
  • duplication / shift + r redo capabilities
  • support for HOPS tools like interactive mirror and Qarray
  • smart hiding of modifiers for quick modifications
  • insert hiding via quick selectors in T panel
  • auto scale system
  • custom scale system
  • auto grouping for quick selection
  • inserts dont appear until mouse is over surface during insertion

and much more. But it's not perfect and this is only the first version. With all projects I am attached to I am commited to providing a unified workflow to users while also keeping things streamlined.

KitOps was made from the ground up to offer a faster and more user friendly experience than our initial offering in Hard Ops. With an emphasis on expandability.

There is a free version available. However there are some restrictions since it is a demo.

Try it for yourself. KitOps Videos / HOPS Red Insert Demo

The videos themselves should show the differences.


How about Meshmachine? How about that?

Meshmachine is a different system going for something different altogether. And that't what makes it awesome.

Meshmachine began as a series of tools to make Machin3's life easier in edit mode but will soon be introducing "Plugs". I cannot recommend his tool enough. I imagine the final version being unlike any tool we have seen before.

KitOps currently does nothing beyond connecting meshes to other meshes with booleans and even simple placement. As you know this can be inefficient and messy when combined with curvature. So planar surfaces are optimal for this if you are not skilled with cleanup and efficient boolean modelling.

Meshmachine takes this in a brilliant new direction. With his inserts you will be able to not only merge them with any surface efficiently, but the normals and shading will be resolved as well. This is alone worth my recommendation for this product. Fuse, Refuse, Unf*ck, UnChamfer, and Boolean Cleanup are tools that fill holes in the workflow of concept mesh creation.

Meshmachine is poised to do great things but this workflow does come with speed compromises due to complexity. This shouldn't affect your decision but this is where Plugs and Kpacks differ. They are 2 very different delivery systems for 2 different circumstances.

Kpacks are intended to just be used as inserts with users having to deal with consequences and ramifications of poor placement or hotlining. And not to mention doubles and shading issues with bad geo.

Plugs will conform with the surface and heal the shading. They both have their place. But in short there is no doubt that we will evolve to meet the standards that Meshmachine will set.

I recommend to use Meshmachine and bring it into your workflow. Our goal is never to compete. If someone can do a better job why not expand on that.


How do I update Hard Ops / Boxcutter?

Q: I haven't used HardOps for a while and need to update. Where do I get the latest update?

Blendermarket: log into your account and go under orders in the dropdown of the upper right list.

Gumroad: log into your account then access the HardOps or Boxcutter pages.

The top file is always the latest.

Q: How do I get up to speed with the tool?

A: In the T panel is an option called Hard Ops learning that is built to help users find the documentation or tutorial content. Every major version I usually make a new course set of materials to show off the tools.


How do I apply a boolean I set up with Hard Ops?

Quickest answer. Apply the modifier. A boolean is just a modifier in your modifier stack. However this isn't the quickest or most recommended.

mir

First lets set up a boolean and examine what is happening.

mir

By pressing (ctrl + ~) I am able to see the modifiers on the object via the helper. This can be an easy way to quickly see whats happening with an object in the 3d view.

From the helper you can apply like and modifier or apply it using csharpen which is one of the primary purposes of the behavior.

mir

Csharpen is being used in the above example to apply the modifier as you work forward thus making the workflow faster and easier than going through panels and menus.

Why does my symmetrize work on the opposite side?

X - Symmetrize will work on either the left or right side of the model.

mir

The selected option of X is rather unique because there is more than 1 version. The default is left handed. You can press F6 to change the behavior post operation as the below example.

mir

But to make it always on the right side by default. - ctrl + alt + u brings up user prefs - addons tab >> search for hard Ops - activate right handed

mir

Now the symmetrize will behave on the side opposite of the default.

Automirror has no wrong side same with mirror mirror since they operate via modifiers.

How Do I Install Hard Ops / Boxcutter?

See Install

Why is the add-on checker not working?

The recommended addons will show checkboxes when the supported plugins are present.

This can have issues if the naming is different than what it is looking for. BoxCutter for example requires the folder is named "BoxCutter"

If the naming is not exact this will cause issues. Just rename the .py to resolve the issue.

The naming is as follows.

This can be an issue to some however it is recommended to just check the folder naming. We are currently looking into improving it but it was intended to be a quick checklist to assist with troubleshooting.

To troubleshoot further you also can run the following command in the scripting area of the scripting tab.

bpy.context.user_preferences.addons.keys()

install

This will show a list of all the add ons present. This is how we troubleshoot this area when the plugin detection is not working.


Why am I having issues when I boolean certain areas?

see boolean tips


How do I bake alpha maps / height maps from a Hard Ops model?

I assume you mean bake in substance painter or get normal / height maps.

Also I must add DecalMachine has it's own system worth looking into for baking out decals to textures.

If you wanted to be lazy you could make a version without bevelling and use x-unwrap on it to get some quick UVs.

Then export the bevelled as the high and the unbevelled triangulated as the low and with the correct settings you should be fine. However the best work is done by UVing and properly creating a low but workflows for hacking your way through exists.

And then exported.

Xunwrap provided some UVs however you can also preview them using operations << UV preview.

Now in substance painter I bring up the mesh and do a quick bake.

The UVs provided will do for such a boxy example however when inserts and material colors are present you will need to accomodate for baking ID maps and so on.

In this bake I'll up the res and allow a little AA to get a nice result.

As you can see from my IDs the material colors also baked into the low mesh.

None of the inserts are present on the low. Its all just the bake. By removing the render and the filters and finally the layers you can see its the same low I used for the block in phase.

So the point of all this is to explain that a workflow exists however it is up to the preferences of you the user as to how you want to go about using the tools in your workflow.

The beauty of hard ops is you can use as much or as little of it as you need for your preferred workflow. But many of the tools are designed with particular workflows in mind.


Why can't I cut using a plane?

I find planes work for complete cutting and splitting depending on the BMESH or CARVE boolean system. CARVE is more stable. BMESH is less reliable but cleaner and can be more prone to issues.

In this example I cut using a plane and it shows no result. This would be expected since this is not a manifold mesh.

A complete cut would more than likely work but planes are always a little more unpredictable.

Notice that bmesh fails while carve gets me the result that I would expect.

Toggling between the two behaviors can be done via the Modifier Helper (ctrl + ~) The default method can be changed in the misc tab of the helper.

Now to show how I would make such a cut.

Notice that instead of slicing I used tthick to add solidification and adjust the amount of spacing in the negative area. And to quickly apply boolean / autosmooth and bevel I used csharp.


What is Cstep / step?

In short.

Cstep - cstep is an sstatus for baking bevels while keeping a bevel modifier active for new intersectional bevelling.

step - bakes bevels while adding a bevel modifier back to the mesh for new bevelling.

See Step


Why is my mesh hidden when I step?

Step hides the mesh when used. See How does step work technically

  • press alt + h to unhide mesh
  • press h to hide mesh

Can I get out of Cstep?

Absolutely. Q >> meshtools >> sstatus reset

q >> meshtools >> status reset will reset any mesh back to a default state. Causing the Q menu dynamic options to also be default instead of cstep oriented.


Why is it called Step / Cstep / Ssharpen / Cssharpen?

The naming made sense at the time but the functions are best described like so. Someday the tools will be unified into something more logical however in the meantime we needed some sort of terminology for naming.

When I was originally writing a book about modelling I found myself saying repeatedly: tab >> editmode >> select sharps >> mark sharp >> mark seam >> mark crease >> mark bevel weight

Over time I just simplified it into that for my own sake however after they became tools the names just stuck. Since it's version 9, changing names might confuse actual users just to appease people who possibly are not even using the tool nor plan to.


Why doesn't (ctrl + j) join an insert to the mesh?

Well ctrl + j in object mode is reserved for joining meshes in the blender API. Unfortunately if you select and insert / AP / BB and mesh and press ctrl + j you are only joining the meshes together which is not the intended behavior.

To properly join an red insert use the q menu system.

Read About Inserts


Can I add my own inserts to Hard Ops?

No. However it is possible but not recommended since it's not user friendly. For custom inserts I recommend the Asset Management. This is a temporary solution but we do have plans to expand this down the road.


What do the different inserts mean?

Orange Inserts are just basic inserts. These can be inserted in edit mode orented to faces.

Orange inserts can be inserted on a series of faces and can be scaled immediately after selection via a modal operation. This allows for scaling to perfection. It even sets the pivot points to individual origins so they retain their position.

Red Inserts are inserts made to be boolean cut into surfaces.

Adjustable inserts are inserts that can be adjusted for additional length prior to being applied.

Red inserts also do not get inserted on faces. They always are inserted at the 0,0,0 of the 3d view. This is because they dont behave well being placed automatically due to the hook modifiers that the adjustable ones have. These inserts also have an AP that allows for surface snapping while also seeing the outside perimeter. This allows for precise placement.

Red inserts are built up out of these 3 pieces. - AP or alignment plane (used for aligning the whole insert) - BB of BoolBox (used for the boolean to make room for the OB) - OB or Object (the object being inserted)

Update Log Explaining Red Inserts


Help! Why doesn't this add-on show activated in the add-on checker!

By using this line in the scripting area of blender you can see all the add-ons activated.

bpy.context.user_preferences.addons.keys()

The Boxcutter add-on folder requires the naming be "BoxCutter"

You can also find the foldername in the addon file area.

This is how it would be fixed in the add-ons directory.

Now I can start boxcutter with Alt + W

Mira tools also is the same way. img

In my add ons folder it is just called mira_tools. For this addon it can get complicated since the naming is rather specific.

I must add that the add on checker doesn't really matter. It was attempted to be a convenience thing. However some issues that users find with it is due to the naming.


Mira Tools

Why doesn't curveStretch or curveGuide show up in the Q menu?

img

Check the add on preferences for Hard Ops under the add on tab. If Mira tools is not enabled you must download and install it.

Mira Tools / Thread

If mira tools is not enabled the icon next to the button will show an error.

img

The below example shows how installing it and enabling it allows HOPS to use it as well.
