@Andrew Shpagin Good change with the default IBL.  Also glad to hear of Jama's involvement/consultation.

With the shader advancements your making, any chance of getting some kind of better looking post process effect on the cavity setting to make them look smoother?

Also, has the voxel smooth seen a performance enhancement?  I didn't notice anything, but just checking if it's been done.  Or maybe planned for.

Thanks!

Relax is now approx same speed as the cuda relax before. But no cuda used, the shaders calculations used instead for the better cross-compatibility.

Здравствуйте . Попробовал скульпт с новой HD все хорошо и считаю правильным решение , так как Pbr шейдер более реалистичен (и видно реальный объем )  , даже в Zbrush мат кап не передает реального объема так как многое затеняет , но в данной HD не хватает освещения сзади    . Я Постоянно скульпчу и моделирую в Коат и после появления инструмента релакс в Zbrush уже давно  не захожу , но эффекта шейдера кожи так и не добиться в 3D-Coat   . Еще чего не хватает в Pbr шейдерах коат это хорошей  SSS , как бы я не крутил и не настраивал его я не могу добиться подкожной прозрачности , как будто он урезан и не хватает прозрачного подкожного  эффекта .!

И еще , по поводу карт Hdri их и так  можно подгрузить , дело  даже не в них  , а в  стандартных pbr шейдерах в которых нет  реализации реального отображения масс и текстур кожи  .  Zbrush , как конкурент все таки не только в том , что может тигать кучу полигонов , но и в в реальном отображении шейдеров .! .. Да сейчас скульптинг в 3D-Coat отличный в плане всего , есть конечно баги , но уже я считаю остались мелочи в плане доработки  , но шейдеры нет ,  с такими   умолчанию шейдерами  , не достигнуть отличного результата .! Еще я не понимаю , почему вы не пытаетесь и не пробуете выйти на другой рынок , это CAM . У вас уже все есть .... Полная программа для создания 3D моделирования  и скульптинга , ваш модуль 3D принтер абсолютно бесхозный  вариант . Я вам говорю , как конструктор технолог программист CAM ... А вот если введете CAM модуль обработки , то сразу появится много заинтересованных в сфере , Деревообработка ,.. Ювелиры,..Стоматология,... . Тем более  из ходя из того , что Autodesk , лишил многих  основной программы ArtCam . Это сугубо мое мнение . Поверти это громадный рынок , в нынешнее время ...

-Go to render room.
-tick greyscale
-switch panorama > colour is back but greyscale box is still ticked.

testing 87, is working fine from my side.

Voxel Smoothing is definitely faster, now, after the new tech Andrew implemented.

Found strange behaviour with paint room smudge tool in 2021 (including update .88).

Very quick brush strokes seem to mostly work as expected (i.e. correct direction).

Slow/medium brush strokes often smudge in the wrong direction or don't do anything or distort weirdly.

Some other factors also change behaviour incorrectly (like position on model or steady-stroke being on), but brush speed seems the main error criteria.

Note: This is just with Smudge selected in the smudge tool options, not Pinch or Expand.

Hi,
-It seems like in the more recent versions of 3d coat the lighting with "cast shadows" option is more flat, and the cast shadows themselves are really weak. Not sure if something changed or I broke something on my end. (I am on v.88.)

image.thumb.png.e6c365e3f8c54234ff2ecfa6fded7c3f.png

Looks like the light is somewhere at the bottom/ to the side? I tried rotating on the one available axis and swapping environments, maxing out the contrast, but that didn't help.

//Something that I have always wanted was actually to be able to freely rotate/edit/create the lights/shadows for the sculpt room and the render room...Hopefully this can be possible some day.

-Also, I am experiencing a much weaker Smoothing effect while using shift+voxel brushes after Cuda smooth boost disappeared. Even at 100% it feels to be at a fraction of the original strength. (Smooth brush in the clay/draw brushes is actually stronger now.) Any chance to get a stronger smooth for voxel brushes back?

Hello @AndrewShpagin, @SERGYI

In 3D Coat versions prior to 2021, to point the program to another configuration directory, we could set an environment variable named COAT_FILES_PATH. This wasn't optimal, but it worked.

Now it seems that in 3D Coat 2021, this variable is no longer respected. Despite its existence, the program keeps on creating config paths in $HOME/Documents/3DCoat-2021 and also, probably because of some legacy reasons(?), in $HOME/Documents/3D-CoatV4. Obviously, I don't want this to happen. I don't even have Documents directory in my $HOME path. I have doc. ;)

So, how can we change the config location in 3DC 2021?.

Having configuration files in Documents on GNU/Linux feels very awkward. They should be placed either in a dot directory inside $HOME (like ~/.3dcoat for instance) or, ideally, in paths indicated by FreeDesktop's XDG Base Directory specification.

 

The second issue I have, is with file duplicates.

I found 295 duplicate files under different names inside the installation path (unpacked from tar.bz2 archive). Please consider using relative symlinks for those files, as this could slim down the unpacked archive size by about 480 MB.

Additionally, many non-config files from the installation path (textures, icons, shaders, etc.) are copied to configuration path at the first start of the program (if config path doesn't exist). This creates even more duplicates of files which, after all, are already accessible by the program. On a clean install, that's additional 180 MB of wasted disk space. Is this really necessary? Correct me if I'm wrong, but I think it's pointless to create a copy of something that wasn't modified yet and is still at its defaults.

  1. Show/Hide Reference Images.
  2. With file chooser dive inside a directory containing images.

3D Coat crashes without output to stdout.

It won't crash on all directories though. For example, with a blank new config, it won't crash on UserPrefs/UserScenes, which contain two jpg files (images generated by 3D coat while saving scenes) but it will upon entering UserPrefs/SmartMaterials.

Annoying bug introduced somwhere on versions .81-88.   If you move volume by gizmoless hotkey, and then undo it, your previous brush gets unselected and more, if you select any volume in this state  with H key - it will switch  to surface without asking. Same happens with pose undo

@Arvart Hi 

Yes, this bug was solved on version 84 and above, please test it. Tkx

- Fixed problem when voxel object modified as surface and you switch to another volume or merge another object into the modified one.
