I can see it on .83

Check Edit > Customize UI: it is hide ?

I am having the same problem and have for some time, it's strange. Currently on 2021.83 and Blender 3.0
Trying to customize ui and un-hide, I could not find it either

3DCoat and Blender, these two apps I don't think will ever be "versus", they compliment one another incredibly well (according to me at least) with mutually exclusive features/tools. It almost feels improper to suggest 3DCoat devs concern themselves with this, but if there ever was an app which I think 3DCoat could benefit from a 1st party applink with that just plain works reliably and well, I'd have to say Blender applink. Might even convert some customers.

(Omniverse a possibility too but that's perhaps uneven given it's a nvidia-only platform.)

It's not exactly grueling to hop between apps manually but it kind of interrupts the flow and feels like a chore

@Carlosan no - its not hidden by the UI - I reverted my UI to default. I really don't understand what makes it appear and disappear.

It seems to me that there is an issue with the radius part of stroke mode with Grow tool.
 

 

Additionally, when depth is above 300% the stroke is a disaster

I ran 4.9.74 at the same time as 2021.84 for the test above : it made 4.9 crash and when I reopened 4.9 I gpt the black shader issue from 2021.83

difficult to fix 4.9 afterwards
Fixed it now, but the particular file that opened with the black shader still does.

Voxel brushes are so much faster than before. Amazing! 

I found bug

1. After changing the position of the Voxel object using Transform without gizmo(move), if you perform Undo to return to the previous position, the object disappears.

2. Press ESC in Transform without gizmo(move) state, the Voxel object disappears.

3.Transform without gizmo (rotate, scale) looks fine.

Fortunately, it reappears when I activate the Primative tool

Hi

Sorry but testing .84 cant replicate that transform issue.

Hello, and happy new year!

I have a serious Performance loss with the last version 84. Might have to do with the shader optmizations.

In an empty new Scene I get:

3DCoat.83: Paint Room: 270 FPS, Sculpt 177 FPS 

3DCoat.84: Paint Room:   30 FPS, Sculpt   15 FPS

on a Geforce 1070gtx.

What happened to cuda options, lots of frame drop with around 5mil voxels on.84,  36 core intel & 2*2080ti , 128gigs ram

Hello

As Andrew said on release notes: 

- I mastered the new technology that will be useful everywhere, especially to optimize anything voxel-related (but not only that, it is potentially useful everywhere). It is calculation via the regular fragment shaders. It is not about compute shaders or OpenCL that are not supported everywhere (and generally not well supported), but usual shaders that work on any device.
It is very important for the future and it took some time to implement and debug. Now it is applied to Smooth in voxels and Grow.

So, no CUDA used, but regular shaders instead. Now smooth and grow work really fast. That was only brushes that was impossible to speed up without GPU.

On build .84 there is no longer CUDA options, as this new technology should replace it.

Please write to andrewshpagin@gmail.com asking for this issue.

Thanks

please run coat, exit in minute or half, send me docs/3DCoat2021/log.txt

And move mouse constanlly during the process

Frame drop in what process?

@Andrew Shpagin

I send you 2 Logs to gmail. One from 83 and one from 84. notice that the Cuda Option is turned off in 83, but it is fast.

Tumble & sculpting voxels  , the cursor jumps off when the jerk happens.

Sounds a bit like the same. My axis cross and the grid flicker for a millisecond.
