3DCoat 4.8 BETA testing thread

Are the Retopo tools (like BRIDGE) shown by your developer, in some of the threads here, available? I don't see them, even though he says they are available.

It will be in next build. Generally, I make builds every 7-10 days now, so it will be soon.

- Sharp edges marking in Retopo room. Baking, import/export supported.

Great! Now it's more possible in some cases to create assets in 3D-Coat only, without any other 3d app. Thanks to the 3D-Coat team!

1) Selecting Faces, the Extrude Faces tool behaves in a strange way. NOTE: The Auto Snap option is not enabled.

2) What has changed to make an extrude in a similar way to other modeling programs? The extrudes I made look the same as the past versions of 3D-Coat ... Any new tools I could not identify?

3) When you select Edges and use the Split tool nothing happens ... just the Cut preview and it does not allow you to execute the cut.

Thanks for reporting (1)

1,2 - seems extrude faces badly works on triangles. I will fix it asap. Try extrude verts  in face selection mode.

3 - just click.

  Yes, I know ... I was clicking the left button and nothing happened. I think the tool works properly, it may be problem with my mouse. In some cases, the tool did not work when I clicked.

Thanks for the improvement in the retopo room .... gradually the modeling begins to take life ...

I think I found a possible Bug.  -- Retopo Room -- Spit command:
When you select Edges, press R to select Edge Ring, then press Insert to make a cut and confirm the action with a mouse click.
The result is a separation of the mesh into different pieces (In this case 4 pieces).

In the image you notice that the yellow loop stops because the mesh has occurred separating.

If this is not a Bug ....
At that time, I miss the command like Merge Vertices .... or Remove Doubles ...

Andrew, what happened to GPU Occlusion Baking? It was so fast. Now, it's back to being slow again, because it uses only one CPU thread!!!! Ugggggghhh. :(

....Just try to bake Occlusion with the Robot. No AA samples, then 4 samples, then 16. No matter how beefy your system is, it hangs for minutes with just one CPU thread calculating. Anything 3DCoat calculates with one thread, is slow as molasses.

It's causing my system to hang.....JUST USING ONE CPU THREAD!!! It's horrible. With 16 samples, it's hanging at 12% 5+ minutes into the calculation and causes a perpetual black screen like this...

Can anyone else test and see if Occlusion baking is borked on your end? Build 4.8.36-SL. It's just abysmal on my system. I restarted the system, updated the video drivers, and just baking occlusion on the material ball or robot from the splash screen makes it hang for several minutes on end.

I do not know I could test as you need, but import robot to 3d coat paint room, then delete occulusion, curvature layers once, and From top menu  textures>circulate occulusions

Light source = sphere, AA samples 4 x,  it seems work (not so slow) as same as before. 

so your problem is retopo room occulusion baking?

and when  Fill Material, as you know it start occulusion baking too, it work without problem for my pc, I am windows 10 64bit user. 4.8.36 build (not SL version,,,) GTX980ti

No, It's Paint Room > TEXTURES menu > CALCULATE OCCLUSION. I think I may have figured out a possible solution/reason. I had mixed results, but at times it was horribly slow. But, one time, when I tried recording the screen to show Andrew, it started behaving for a while. 

It took several tries and when I went to 16 AA samples, it finally came to a grinding halt. I closed 3DCoat started again, but this time, I went into Windows Task Manager and under CPU AFFINITY, I deselected the first 2 cores > tried again and suddenly it works properly and I can see the GPU does the bulk of the heavy lifting.

It must have something to do with Windows scheduling, because I got the idea from the following video, regarding ThreadRipper slowing down because of this issue. I was monitoring the activity of the CPU and GPU on Task Manager the whole time and when it worked right, the GPU would get under roughly 100% load. When it wasn't working right, it was the GPU not getting hardly any load and just CPU core #1 pegged to maximum. And it would slow my entire system down, as if everything depended on that one core.

Is there a way to reproduce?

I'm on Win10 and use the the latest SL beta in GL mode. This happens to me all the time, when I have ghosted volumes in the vox tree, they become unghosted upon save/autosave, every time.
I just assumed it happened to everyone, not sure what else I can say to help reproduce.

@Carlosan Attached Here is a small doodle that takes 10 second to save on my computer, when much larger files take a second or so. Please let me know if you are able to "reproduce".

About the latest version, shouldn't the right click menu in Retopo room appear only when the select tool is active ?
It kind of breaks the add/split tool : it can't easily be used to merge vertices anymore, because that menu pops up instead.

@Andrew Shpagin

Could you please fix this bug? It's present in every version of 4.8.

Bug description:

If you change an object with the Transform-tool you get a non Uniform message at the bottom of the program-window (status message).

001-nonuniform.png.15b1c7cb52b56f40bdbad18fbba31c0a.png

To make the object uniform again one should click "TO UNIFORM SPACE" (located in layer-context-menu).

2129333534_touniformspace.png.f99d7885aab424586f342c0716f396e9.png

 

But the "TO UNIFORM SPACE"-function breaks/damages the object.

 

You can see it when you sculpt on it and make an UNDO.

 

Examples:

bug2.png.32caa839aa698aff27145503360e03f5.png

 

Thank you.

P.S.

This bug is a nightmare! I don't know why nobody fixed this yet.

I think the "Sharp edges" tool should not be the first item in the Tweak section on the left panel. Brush should remain the first, because it is the one you need the most often, imho.

Boolean operations that used to fail a lot seem to work better all of a sudden ? Things like import-on-brush, the close hole tool ?

I notice that Resample now seems to go through voxelization, which is bad, because it causes narrow areas to merge.

Res+ from a low poly still makes a surface mesh explode after a few times.

Possible Bug in layers:

In version 4.8.37 SL (DX):
When I go in the File / New menu ...
Layers used in the past project remain present in Sculpt Layers / Paint Layers.
So in the new project, I have to click the Delete All Unused Layers button to reset the layers and create a new base layer.

Tube/array,  radial scale is affected by brush radius of points.  Inserting a point with a different brush radius to adjust a curve will get uneven thickness, I can't seem to find a way to adjust thickness on that point.

Please write what version of the program are you using? In version 4.8.37 there is no such problem.

Try changing the point connection type.

Hi!

As I said it's in every 4.8 version.

But I just found out that this bug only happens when in voxel mode/layer.

000.png.523b3a4a8b4f1a6018e580fa7e23b043.png


I put together a new description below.

----------------------------------

1. Start with a volxel-sphere.

0000.png.c7a7f26d93bc1fb964dcc34accd092e0.png

2. Press the "To Uniform Space" Button.

002.png.d90add3129428b67611f03ddfc2c907a.png

3. Sculpt on voxel-sphere (e.g. with grow)

003.png.f04f795b6ed7dade4413f9f6c590e6f1.png

4. Press UNDO.

005.png.b761a98eb05251a0bc9cdbd89e79c319.png

5. BUG!

006.png.c1ef973c00ad15b9a51162f33005a3cd.png

 

The "To Uniform Space"-function/button (in voxel-layer) breaks the object!

Hi,

Geometry / HighLight function is not working to me...  (I'm using  version 4.8.37 SL (DX) )
Maybe bug?

All these bugs work every time. I know a person whose computer is weaker than mine, but at the same time almost none of those I wrote about are experiencing. At the same time, sometimes in the new version, it does not work what worked in the previous one, and at the same time it was buggy and continues to be buggy for me. The fact that it works for you does not mean that there is no problem.

Of course, all combinations of factors of computer hardware, system, installed programs, it is difficult to take into account, but please at least try to correct errors.

I shot more than 10 videos with playback of bugs, but less than half of them were corrected for the five released versions of the program.
