can we get the Wintab wacom offset bug squashed soon?  Using Tablet PC is awful as you get the text pop up etc around your cursor. 

Forwarded to system programmer, sure it will be corrected soon.

Hi,

There is something trouble to cause a crash often on smoothing of voxels/surface, isn't there?

I've experienced that some times in 2021.06.

Now I don't have any scenes to re-produce it, dedicated scene or dump, but if there is any option to send dump or crash report then I'd like to know it.

Ok. I got the 3d primitive working in the retopo room. Deleted the user config files in Documents and restarted 3D Coat. Some conflict resolved I guess. Nope Ignore that. The Preferences-->Beta TAB-->Treat Retopo groups as materials is the culprit. If I disable it the 3d primitives mesh is not generated in the viewport.

Thanks for that catch, fixed it in the upcoming 07 build.

The best is to Print screen the crash report on the screen (on Windows) and drop it to this thread. As in one of the previous posts. I am looking all very carefully in this thread.

3DC 2021.04 Mac version.

 

Very often hangs while autosaving. Very annoying... the same was on 4.9 version.Possible to fix?

 

Were you using "On pen" in the Import tool? In case of massive usage, it may lead to a really long saving time. It is fixed in 06.

In 3dcoat 2021, I've never seen a crash report window's appeared.

Past, 4.x, a crash report which have callstack-like or error messages-like  have been appeared but its characters were unreadable as encoding's completely broken. Because it may be on Japanese Windows(system encoding's problem), I don't know.

Minor:

Start menu subcategories, some items duplicated.

20.07.21 2021.07 [stable]

- Fixed multiple problems and inconsistencies related to direct painting over stencils and materials using PreviewOptions->Paint over image

- Tools works correctly in general, with no random lines and other buggy stuff.

- Correct alpha direction

- All modes in E-panel work correctly in image editing mode (that's big deal). Of course curve tools may be used in this mode as well.

- It works correctly with pressure and snapping.

- Materials navigation panel tweaked a bit - edit button inserted for ease of finding the edit feature.

- Correct materials duplication if the color layer was painted manually.

- Correct the direction of the pen in radial stamp mode in all modes - sculpt, paint, uv paint, paint over stencil/material.

Other fixes:

- Fixed potential crash during startup (as reported in this thread).

- Corrected snake tool

- Bake shader with reflections in Light Bake Tool

- Fixed "long memory" issues when render settings or spline objects are migrating between projects.

@Andrew Shpagin
It was reported before, uninstall do not delete program from the list

I noticed tabletPC produce slowing in viewport, i am using vertical sync, it is always 60fps but noticeable slowing down compare to wintab mode.

 

This bug still persist 

and this

could someone explain how to make this work ? "Bake shader with reflections in Light Bake Tool "

I suppose this is what is usually called "bake light with environement" elsewhere, which is something I really wanted, but all I am getting is something like this whichever shader is used

[sprayer]

@Silas Merlin open shader ball for example, fill layer with any reflective shader, bake your reflection and it creates reflection layer in texture

Thank you very much for the video, Sprayer.

So, does it not strike you as odd that it is called "bake shader", when it works only with smart materials, not shaders ?
This is great, I got it partly working

So, since it is called "bake shader", I want to bake reflections from a shader, not necessarily a smart material like in your video, right ?

Ok, not sure of the order in which I tried things to get where I am in the screenshot above.
I did this:
-open default ball
-select default rusted metal shader
-autopo
-bake
-"bake shader"
>this resulted in a white coat on most of the ball, with an unpainted circle at a pole, and random dots at the "terminator" to speak in astronomy terms.

Next (I think), I sculpted the sphere a bit and turned it to surface, then tried to "bake shader" in vertex colour. This resulted in the screenshot in my previous post.

After seeing your video, I baked the sculpted sphere to the original retopo of the unsculpted sphere.
when I did "bake shader" on this, I got what you see in the new screenshot above :
Only the areas that were sculpted (where the normal map is not blank), does the "bake shader" do anything. Where the normal map is blank, I get the white coating.

I believe this is not expected behaviour.
Now I am going to try with a smart material and I expect it to work, as seen in your video.
So... "bake shader" to bake.... smart materials ?

Paint Room

Add a mesh for PPP, example sphere or cube mesh

Use Bake > Paint mesh->Sculpt mesh

Command destroy paint room mesh when it is imported on Sculpt room

i believe this is due to the alphas... change it to a square alpha and it more or less feels the same

That's better to ask Andrew)
I think it work only on uv, so only for smart shaders
I think it's like render elements baked reflection what you may compose on some painted object instead of painting reflection by hands, other way of use i cannot imagine. For realistic work it's useless as it will looks fake at rotation

in v4.9 it works fine
