3DCoat 4.8 BETA testing thread

I've always installed 3d-coat using the installation tip of the video tutorial, which installs the 3d-coat always over an old installation, pointing to the address:
C: \ Programs \ 64bit \ 3d-Coat \ 3dcoat_v4_8
and that way, I do not have thousands of folders for every install I make of 3D-Coat.

@Javis,

That's a good tip. I just install every update that comes out and then suddenly realize that I've got like 8 versions taking up space on my drive.

Autopo in sculpt room dosen't work. anyone to confirm?

Yes, I was having trouble with it too, both that and the Instant Meshes. If go through the whole process, then nothing appeared in the Retopo room.

delete all of your config files from: C:\Users\YOURUSERNAME\Documents\3D-CoatV4. Those files will have the word "Options" in them.

@Javis,
I just updated the drive of my GTX 970 card and I deleted all the options files from the folder: ... \ Documents \ 3D-CoatV48

Unfortunately, I still have issues with Brush performance. Very lagging ...

I installed 3d-coat using that file method: "coat_data_path.txt" that I direct to another hd on the computer.
And in the other hd I also have the "options" files ... Do I also have to delete these files?
thank you :)

It is true! Especially if you always install all new versions. I always had a folder for each installation. Absolutely crazy !! After this tip ... you always have a single folder for all the updates.

I do not know if this would be a problem, but I also used the file method "coat_data_path.txt" directing part of the install to another hdd so I do not lose my custom files (presets). So, I do not know if in the future I will have some kind of problem with newer version installations.

Yep Autopo gives a Crash.

 

Yet I must say I worked on SL for about 4 Hours now and just 0 Crashes I almost forgot that this is a Beta exe-- It felt real stable for me. just Autopo did remind me :( .... I tried all kinds of Complex stuff Back and forth //  10kk Model all running rather well!. Keep it up!

I'm sorry I just can't use 4.8.39
there is the retopo room that makes me crash, and the Space navigator that resets to default every time I start 3dc

I have already deleted the files options configs:
(Folder 1) Documments \ coatv8

(Folder 2) otherHD \ 3dcoat (here because I used the coat_data_path.txt file)
And I've also updated the gtx 970 card drive.

Unfortunately, on my computer, I'm having a very low performance (4 fps) in 1.5 million sculptures up.
Actually, it has become very difficult to sculpt in which each brushstroke gets extremely slow and I can hear the video card "forcing".

I do not know if there would be any other solution for me to do...
The worst thing is that it seems that this problem only happened to me.

I think I've figured out what's going on (surface mode - performance of the brush).

Could someone please do the following test?

1- Choose Surface Sculpting / select Bust

2- In VoxTree, click on the top of the hierarchy (Bust) with the right mouse button and choose the option:
   - Merge Sub-Tree

3. After, In VoxTree, click on the small button twice (Increase resolution of the current object)
The Bust will be about 3 Million Tris approximately.

Now, choose Clay Brush without using Remove Stretching and please try to sculpt the area around the Nose and the front of the face. Test the clay brush on this bust.

What was your result?
I would like to know of you how the Brush performance was, could you report if the fps will drop to 4?

------------------ Solution:
Please, could you test it too?

After I pressed the Enter key, the 3d-coat generated another mesh with approximately 4.5 million tris.
(More polygons than before)
When I went to test the clay brush on this mesh, Brush performance on 3D-Coat returned to normal... I returned to sculpting fluently now, with no loss of performance.

Could you test this too?
And after that I hit the button (Increase resolution of the current object), the bust was 18,150,000 million tris and the performance is excellent ... sculpting normally and without loss of performance!

I did not understand why after the Merge Sub-tree it became extremely impossible to sculpt. The mesh was "heavy" for sculpting, even though it had a few million polygons.

I'm doing some tests with clay brush performance and I'd like to share with everyone what I'm discovering ...

In those tests, I noticed that depending on the type of mesh you have.
For example, I sculpted a face with live clay and dragged it onto the Models palette without decimating. This face has 1.7 million tris.

I created a new scene, I went to the Models palette, clicked on that face of 1.7Million, and I imported it for the surface mode.
First, the performance of Clay brush was normal.
So I clicked on the Increase resolution of the current object button once and the face got 6.8 million tris.
So I started to have a drop in brush performance. Not as the problem I was having with the Merge Sub-Tree, but I think the performance of the brush fell mostly in areas that should have a higher concentration of polygons.

I do not know if the Increase resolution of the current object button is causing this problem with brush performance. Of course the purpose of this button is to subdivide the mesh, but I'm suspecting that after it subdivides something is happening with the Brush performance.

I'm guessing because when I was with a mesh of 18 million polygons (through the ENTER KEY and hit the Increase resolution of the current object button) I had no loss of brush performance.
So when I was using a mesh with a structure generated from LiveClays, then I pressed the Increase resolution of the current object button and that mesh was only 6 million tris. The performance of the brush has dropped.

So, I suppose it should have some relation also with the Increase resolution of the current object button to decrease the performance of the brush in the surface mode and also in relation to the type of structure of the Mesh that you are working.

I may be mistaken, but after testing on a mesh structure generated by liveclays, enter key (voxels), bust that comes in the program, I begin to realize that there is a relation of mesh structure type, increase resolution button, and Merge Sub-Tree with brush performance.

Instant meshes works here. I only have problems with AUTOPO action. Freezes everytime.

I tried to follow these steps and it was working okey for me.

There are things that only happen then with a single person.
Everything I related happened here with me. Very strange. I am very grateful that you have taken the test to tell me about it.
Honestly, I do not know what's going on.
Thank you very much!

Can you maybe once more time test the same scene in v38 and see that issue is not there. I did the same thing with my AUTOPO issue and all works okey in v38 so it's confirms that it's v39 issue.

@haikalle I'll do the same here then... I'll see if the same things are happening related to the performance of the brush.

 


In this new version, when I use Autopo and Instant Mesh (auto) for me it is working ... but what is giving me problems is the performance of the brush in the surface mode.

Ok. AUTOPO works with some meshes. But if you take the biggest sphere from starting menu then it should not work.

Very odd. Now I tested with the same mesh that didn't work before but now all works as expected... Interesting.

I installed the old version of .38 and I re-done all the tests I described here:
- Bust Merge Sub-Tree
- Bust Mesh (Voxels - Enter Key)
- Face Mesh made with liveclay that is in the Models palette.

My result was exactly the same as the new .38 (39) version of Clay brush performance.

Very strange because I'm currently working on a project in which parts of the character is between 4 million and 20 million. And during that project I used Remove Stretching in the Brush ... I did not have that low brush performance.
But when I did these tests with different generated meshes structures and with the increase resolution button, I had this bad performance on the brush.

I have no idea what's happening to me about lagging at the horrible performance of the brush.

I took the opportunity to test the autopo and instant mesh (auto) and it worked in the same way as the new version .38 (39).

I think I found how to see my bug:

I deleted all my 3d-coat folders from document.

1. started my 3d-coat and set my serial

2. Selected the biggest default sphere and try to AUTOPO it. It dosen't work.

I just reinstalled the newer version of 3D-Coat .38 (39).
And I did the Autopo and Instant Mesh (auto) tests on the biggest sphere of the home screen and it worked correctly here as you can see in the image.

I just found out one thing about my brush performance problem on surface mode.
Bust test (from the initial screen):

- I subdivided twice the Bust by the Subdivide button that is in the Surface Tools in the Brushes. The operation generated me 3.5 million tris. The result is that I had no problems with brush performance.

image.png.cc5a53b1d256a5e6065d07970b27b2a6.png
* Then I subdivided Bust again by subdivide button that gave me 16.3 million tris and I still had good brush performance. The performance has dropped a bit, but this is acceptable for the amount of 16.3 million. The performance does not look good in areas of very high concentration of tris as in the nose. But the overall performance is good.

- Again, I subdivide the mesh twice by the small VoxTree button (Increase resolution of the current object). The operation also generated me 3.5 million tris. The result is that I had problems with a lot of lagging and very poor performance of the brush.

image.png.b1b85baa8e99e722aba86f5574b5025c.png

In this test I conclude that with me the type of subdivision directly influences the performance of the brush in the surface mode.

So fine tuning on the algorithm? Maybe something like,  If adjacent is vacant then pass on.

This in reference to an earlier post.

I installed 3d-coat using that file method: "coat_data_path.txt" that I direct to another hd on the computer. And have no problem losing my custom things (brushes and etc).
 

Though it may not cause any problem, but for other new users or if someone hope to know more easy way to use custom user directory,  I recommend this link pdf (and Carosan already offer link in 3d coat forum topic  too thanks)

 

http://pilgway.com/~sergyi/Docs/CustomDocumentsFolder.pdf

so you may only need to set enviroment  "path" , as discribed.  before I had used the "coat_data_path.txt" but, set enviroment path seems more easy and maybe we have set enviroment path , then know well how to set path (eg install python ,java etc)

Then I hope to report one problem which I now start to play new beta ^^; (3d coat 4.8.39 SL) windows 64bit (OpenGL)

Usually I do not use full window, then I often edit window size, but when I  edit window size, by just drug border of 3d coat window, it again and again open start menu,,(of course I closed it),  ,I do not know why it happen.

For a long time I've used the "coat_data_path.txt" method.

So is there any difference or advantage of the "enviroment path" method on the "coat_data_path.txt"?
Which would be the best?

What do you exactly mean? I need steps to reproduce, scene, some explanation.

when press export button in 3dsmax model doesn;t appear in 3dcoat. It opens coat and import nothing.

It happens in 4.8.38 too (and 4.7.xx), but only when you just start 3D-Coat and immediatelly close Start Menu with that little cross at the corner. But if you choose something from the start menu (let's say Voxel Sculpting, or Paint UV mapped mesh) it will never happen.
