Hello! Coat2024.31

In "coat.pyi"  in the new function:  bool = false should be "False" (Typo)

Search Material is good!

All the Best

@Andrew ShpaginThe fill tool currently doesn't use these settings to vary hue, brightness and saturation:

Could this be added?

Also, could these other settings be added to Brush Presets? Currently they aren't

ive been getting weird "bugs" if i autopo anything regardless of the amount of polys ... it generates like 10 massive faces , then i restart 3dcoat and it will retopo just fine ,

Does this happen if Hard Surface Retopology is selected?

ok i tried a few other things and noticed its mainly on meshes imported 

[Elemeno]

all im getting is crashes on a mesh with 10mil tris

Please give more details so that we can repeat this and pass it on to the developer.

Thank you! I managed to reproduce the bug. Now I will pass this on to the developer.

There may be a bug, but just from watching the video you provided, I would use a different approach to this kind of model. It may not seem like a very complex model overall, but it does have a number of complex shapes, which make it harder for the algorithm to do its job. For example, the teeth and eyeballs, if done separately, will have a good result. Then the rest of the body, I would do separately, making a duplicate that reduces the amount of small details (so that the only thing Auto-Retopo needs to focus on is the larger shapes and forms). Once you are finished with the Auto-Retopo generation, you can delete this dumbed down duplicate and use the high resolution original for baking purposes.

Also, before running Auto-Retopo, I try to make the duplicate a Voxel object > RMB the Sculpt Tree layer > choose FILL VOIDS. Sometimes your model may have little pockets inside (usually from working with Voxels and resulting from cutting and merge operations). This step will remove those, if any are detected. They can adversely affect the Auto-Retopo result and even cause crashes.

The problem is that the Autoretopology operation sometimes does not produce any result at all and does not even create a layer in the Poly Groups list.

@Elemeno 
Defining a workflow is what allows for optimal use of the tools and what defines us as artists.

Where will the exported model be used? In previz, cinematic, game? 
In which render engine? 
Will the model be rigged later? 
Will you use uDims?

The autopo algorithm (it has been improved) is very good, but it is not magic.
There is no tool to do it fast, do it pretty, do it well, just by touching a button.
All that step need hard work.

The algorithm looks for ways to wrap volumes with surfaces, it is important to separate the model into similar "shapes" parts so that the process is effective.
Putting hands together with teeth, tongue with head, hardly gives a good result.

If it does not give results, it is the way to recognize that we have requested an operation incorrectly.

This video shows how to create polygroups for each area of the model, and thus have a good baking.

its ok , i just wanted a basic remesh but noticed auutopo doesnt work , oleg managed to recreate it too

If everything happens automatically at the push of a button, then why do we need designers?
@Elemeno , you can lose work.

im not sure what this means?
 

are you saying autopo shouldnt be used? 

i was only posting a bug with the tool .... not sure what ive done wrong.

[Carlosan]

Autopo will be used without any issue, the hard part is to learn how and when.
This is not a bug but your path of learning the software.

It is difficult to help if you don't explain your current workflow

No.
Any tool must be used correctly.
We have 3 technologies For Retopo.
Manual
Semi-automatic (Smart Retopo)
Automatic (autopo )

autopo didnt generate any mesh , thats all .. ive tried a few things but nothing

I think there was some misunderstanding on his part. He must not have noticed that Oleg also confirmed the bug. I think he assumed you were not using Autopo correctly (because some of the objects/parts could or should have been Auto-Retopologized separately (ie. the Teeth, Belt loops in the pants, etc.). But, even if that is the case, there should have been a mesh generated, so you could see if it is doable without stroke guides and such. A bug is a bug. Could you send me the file (or a dummy version of the model) via PM, for me to test and see if there is an issue with the mesh itself? It will not be used for any other purpose, but testing alone.

personal tweet:

I want to use multi resolution in retopo/modeling room.

if there is multi resolution for Retopo/Modeling room, I can use quad polygon multi resolution.

even if voxel/surface can not change from triangle to quadrangle.

This is a great feature request! Passed to developer.
