Now there is a workaround :
-create a temporary lowpoly in paint room
-do whatever you need a uv for
-do : Bake>take subdivided mesh to sculpt room
-reproject your pattern to the original sculpt.


EDIT :
BASICALLY, NOW, FOR EVERYTHING PEOPLE HAVE BEEN WANTING UV IN SCULPT ROOM, WE CAN DO IT NOW AS DESCRIBED ABOVE.


 

Thanks I'll try it.

Here's something I've been asking about for a while. I don't know if there's a tool that could be made for it but I've wondered how people sculpt a regular pattern around the model, for example the hexagon pattern on Spider-Man's costume. With a texture you can just do it with a UV but in sculpting there is no UV. Cube mapping would have obvious seams.

I'd recommend investigating Tissue Tools for Blender by Alessandro Zomparelli and using them in conjunction with 3D Coat boolean capabilities.

The surface pattern on the piece below was created using this workflow.

2021.66

I have discovered a destructive bug with pose tool, but it's very hard to reproduce and had it happen only seldom a few times lately. Tried to deliberately reproduce it just now but gave up, just want to describe it if anything.

I've experienced it since 2021.55, but it might be completely coincidental because after that build I have used pose tool much much more than ever before.

In Sculpt room,
1) use pose tool on vox or surface object,
2) mask area as pose area
3) rapidly use gizmoless scale transforms (Shift+R + X/Y/Z) in succession
4) sometimes, it is as though pose tool momentarily "forgets" it has masked area, and scales entire model during a gizmoless transform operation instead
5) So scale of entire object can happen, but after that you can still see area is masked for pose, more scale operations will only be on that area again like before
6) It will have scaled entire object, but completely forgotten it in history! so it will not undo the scale of entire model, only undo scales of pose area relative to transformed object
7) Since entire object was inadvertently scaled but it cannot be undo'ed, only solution is to try and manually re-scale object, reload object/reload file/load autosave.

Again, hard to reproduce and rarely happens but might be worth to be aware of

- Take a shirt

- Isolate the parts you need to texture, UV it.

- Import same mesh to sculpt room as surface (increasing resolution) and to paint room

- Create Smart Material with seamless texture, fill tiled with UV projection.

- Bake > Take subdivided paint mesh into the sculpt room > FlatPatches > Vertex count 3M

- Re-project

The latest version uses a permanent license, the curve command loading curve shows only Spline and eps, uninstall the purchased license, install the forum trial version license, you can load Spline and igs, eps, what am I missing or there is a problem with the settings ?

Newest version

Paint Room - Freeze tool,

Create a new scene select Paint a UV mapped mesh, select a sphere default settings, paint a freeze area.

Go to freeze menu select expand freeze area or try contract freeze area, neither of those give expected results, smooth does not work also.

Tested older versions of 3d Coat bug is there too. Found posts about it from 5 Years ago in the forum and bug was confirmed back then.

I've noticed this often, I find a bug in 3d Coat come to the forum and do a search and see it was reported literally years ago, confirmed and then never fixed.

How does that occur?

doesn't bother you, during your steps after clicking on contract/expand, the freezing menu opens just on hovering without clicking on it again, this bug make me crazy

news on the Linux builds

Here is an update regarding "3DCoat 2021" for Linux. "3DCoat 2021.66" for Linux has been successfully compiled and linked under Ubuntu 20.04 on my desktop. But because there were a lot of changes recently there is a startup crash that is currently under investigation.

Thanks for the update, Sergyi.

Almost there, then. Great!

I figured it out how geometry painted when sculpting. When u try for example (move tool), in that moment when u release button, geometry painted. Maybe any suggestion how to erase color info? Who know script command, or anything how to erase even from one object? Its weary annoying, when you have 50+ objects. My system is Ryzen 3950x, ssd nvme for system disk and separate ssd for project. When i try to save file, saving time is 2+ minutes. Without color info 5 sec.

Right click the vox layer > to global space (or to uniform space) :
the volume will no longer be "painted", that is, all the sculpt layers information will be erased.

Sculpt layers (sculpt strokes stored on the active paint layer in the paint layers panel) work only in surface mode. They do not affect voxels, except in the case when you use a hybrid tool, that is a tool that is a surface (traditional mesh) tool, but is made to work also on a voxel volume. This is achieved by temporarily treating the volume as a surface mesh.
You can test this by changing the depth of the active paint layer while you are still using the move tool.
After using one such tool, once you select a pure voxel tool, the volume is no longer treated as surface. It reverts to voxels, however, the changes you made while temporarily in surface mode is falsely detected as being stored on a sculpt layer (falsely, because only actual painting survives after voxelization, it seems).

Move tool in your example is itself an exception : it can be either a pure voxel tool (not affecting sculpt layers), or a surface tool, depending on whether you tick "voxelize immediately" in the tool options.

Hopes this help understand the situation, if not get rid of the annoyance.

Thanks for this. Its works, but (to global space) make some change in geometry when use, (to uniform space) work better.

I know before, how hybrid tools work and know how voxels system works. But in the older version(like 4.3) it doesn't affect on vertex color. My suggestion, add toggle in preferences menu or in tool menu option off vertex color paint when sculpting or add in menu (Erase vertex color) for multiple objects(if only for one, its better then nothing).

I know how its work. And annoyance doesn't disappear if this issue doesn't gone. If i knew where i can get info about (script commands for 3Dcoat). I will make my own script for this issue.

I checked in more detail (to global space) and (to uniform space).Conclusion it's doesn't works. They don't erase vertex color, just delete color marker in voxel tree.

ok, then try this :
-click on V to turn to surface. when ask if you want to bake colour information, try one. (try the other later)
-
Once in surface mode, click on the S to return to voxel mode.
-delete the active paint layer in the paint layers panel.

See if this solves your issue. If not try again with the other option (baking or no baking color)
