Steady Stroke feels really weird in Paint-room.....
The higher the number, the worse this problem is.

Looks really terrible, but on all my tests it works as expected. Maybe you enabled some unusual options like "Sharp shape" or "Paint with dabs". Try mouse and pen. Is there difference?

Question about internal 3dcoat renderer. It seems very fast with pretty good results. Is this an advanced renderer or is it a simplified one, as compared to other industry rendering solutions.

This is a simplified renderer, screen-based reflections, and this is not re-tracing, it is multiple frames superposition render.

But the fast ray-tracing render is also close to being done.

 I hope you can notice small problems in pixels. Imho it such waste 4k in <43" especially for content creators what should see all imperfection. Some people cannot see noise on renders in such sizes

Can anyone tell me why this happens when using matcaps. On flat surfaces when the camera is moved to a sharp angle of view the mesh becomes significantly darker. Just to be clear I only see this on flat surfaces. In other apps, I have not found this issue. Not a major issue, but can become a little distracting when rotating around a model continuously. Might be a little knit picky.

It should be so. Matkups is just baked light, it is not calculated in real time. Fake material. I made a set of matcaps for all occasions a long time ago, maybe they will be useful to you. https://dmitrioos.gumroad.com/l/matcap3dcoat

I am still trying to reproduce, but still can't. Works super clean on my side.

So questions:

1) Try Edit, prefs, Brushing, Wintab, then Tablet PC. Any difference?

2) Is there any difference if you set 4K res for the monitor or 2K?

Please show the Brushing tab in preferences.

Why payment for a product occurs through a payment service, where I have to pay more money for VAT, while in Steam, gumroad, Blender Market, anywhere else, where I have ever bought something, it is most likely simply included in the price , and it won't be a surprise for me that I will pay another twenty....fifty euros in excess of the indicated cost? Why is it done this way?

Are you tried with steady stroke 40+?
I already tried to change tablet interfaces, screen resolution, any settings in brush option panel all the same. Without steady stroke it works fine.

 

edit. looks like this option fix that behavior

No, this option is not being used.
In addition to the high Steady Stroke, the lower the Brush Size, the more prominent it seems.

Looks like I've found a temporary workaround.

When I changed from 'Connective Picking' to 'Volume Based', the symptom disappeared.
I don't know what the difference between the two is, but it's been resolved.
I'll have to look into the documentation for that option.

In addition, the symptoms are different depending on the brush alpha.
There are things that move regardless of Steady Stroke.
A typical example is 'chain_227B'.

I suppose, if it is caused each brush default setting behavor. Random rotate or jitter etc

Did you check Brush option panels setting?

eg the chain is use Paint with Dabs otpion (activated) as default.

Sorry for continuing to write.

I'm confused. In the 'Paint UV Mapped Mesh' example sample, I noticed that there are some that do and some don't.
(Addition: After more testing, other samples also have problems, but not as much as the checked sample.)

Please test it with the sample checked in the image.
This is the sample that most reveals the problem.

 

Test
Steady Stroke : 40
Brush Radius 0.1
Connective Picking
 

And a new finding seems to be affected by camera distance.
Even with the same setting, the problem gets worse as the distance of the camera increases.

To summarize the problems we found...
- Steady Stroke with high numerical value (eg 40)
- Brush Radius with a small numerical value (eg 0.01)
- Connective Picking (Volume Based is fine)
- As the distance between the object and the camera increases.

The problem gets worse.

- Materials/stencils control panel cleaned up, looks better, more compact, icon-based. I hope you like the new design. Also, stencils keep scale and states when you switch between them. But CTRL-click acts as before - then settings from the previous stencil will migrate to the newly selected. Pay attention to "Uniformness" and "Extract Bump" in extended settings.

- Splines/models/joints included in the activity bar.

- Fixed possible crash during the sculpting.

- Voxel brush engine quality of stroke improved.

- Probably fixed the stroke issue in PPP mode.

- Fixed old voxel brushes - Airbrush/Buildup

So far the only way to save a stencil position for later (after saving an reopening) is to save it in a preset.
presets are a mess imho and too difficult to use for that purpose (how you you find your stencil in a huge list of presets?)
I think there was another way before, or was it always presets ? because the other thing I remember is that when you did this, it created a huge file in the document folder for each stencil.

Anyway, I think it would be good to be able to bring back a stencil in a given position, because they work well with the projector feature.
Say you set projector from stencil and sculpt with that.
When you save and reopen the file, all you have left is the projection.
The stencil is useful in addition to the projector because you can sculpt detail directly with the stencil. (once you have found the shape by sculpting, you set the voxel resolution higher and then use the rectangle stroke mode with for example the airbrush to add surface detail to the basic shape).

there are things you can do to help restore the stencil position of course, but it is never 100% precise because the scaling tool in the stencil "control panel" is/was not that precise.

one solution that I think could be convenient (ask others) would be to store the stencil in saved view (CTRL+up)

Here is a problem that persists since 4.9 : in "from camera", the stencil position changes relative to the 3d scene when you change rooms 
(AND within a room when you change the style of the left tool bar).

I think it would be nice to store the stencil and its settings in view preset (ctrl+up) if the stencil is opened while saving the view.
also would be nice to save the view in a stencil preset file 

it can be an option in settings or just a small dialog window asking every time you saving stencil or view

Several rules:

1) Even if the tool appears in the script several times it will appear only the first time.

2) If you hide the tool via "Customize", it will be hidden everywhere in the tool panel in this room.

So the way is not to hide, but edit the script of the room manually from the room settings and reorder as you wish.

Thanks for the tips.

I had already started trying to learn how to edit the scripts. I'm not a coder however so it's slow going, but perhaps I'll figure it out eventually.
