@Ctc_nick bug confirmed and reported  @jdoublej please send the presets asking for this issue at support@3dcoat.com thanks

The fourth month of expectations, the fourth month of hope.

The Alphas for my Tool Presets are still not working in 3DCoat-2024-20.  So I will continue to use 3DCoat-2024-18 until this is fixed.  Just wanted to bring this to your attention, thanks.    

Ok, can you try once more? Here the original blender cube. blcube.3b Use PPP without Baking or with, doesn't matter. Turn all Depth, Gloss, Color on. Paint over the diagonal of the faces. As if it would be triangulated.  Now you should see something like i posted. Uh and when i turn to low poly it gets screwed. key[6] The cube was imported using applink.  

I was testing this new feature on Modeling room moving vertex and using Mesh > Export. - New option "Edit->Prefs->Tools->Don't group vertices per objects in OBJ files (like ZB)" for vetter compatibility when you need to keep the vertex order in OBJ files. Anyway, Coat preserver vertices order, but in some case it is not enough, and vertices should not be grouped. In this case you need his option. * This option is only available moving vertex with symmetry turned OFF.

In this blog I'll discuss 3D characters in their sculpted, high poly or voxelized form as ‘most’ Text to 3D AI Gen meshes, consist of this high poly density when generated, complete with texture. https://www.draw-it.co.uk/blog/sculpt-and-ai-vertex-paint# 

I cant replicate, what set do you use ? If it is a custom model (not default one) please share it to take a look.

It could be either...or even by attributes like UDIM number per uv island you can apply beforehand. Also, your method of mesh replacement in 3dCoat worked.  Thank you so very much. You saved me a bunch of time. I did not know about  this method.

Yes, udims management looks friendly. Some love into 3DC can help no doubt. In each UVtile do you separate udim by objects or by materials ?

Thanks Carlosan, I will try your suggestion.

Here is an example of Doing UDIMs in Houdini. This model has a single uv set. Apply the UVLayout tool and move them to the next.   UDIMs_Houdini.mp4

Hope this help, source How to non destructively re-import a different UV layout for your mesh without your texturing breaking 3DC project layer paints & materials onto the model to be able to re-project in case of UV layout changes.  Do you have a painted mesh… …but need to replace the geometry because UV layout changes ? Follow this steps: – Switch to Retopo Room and Import external mesh – Bake object for pixel painting – Switch back to Paint room, now you can see 2 UV layouts with old textures projected into the new mesh – Delete the old mesh and continue working

Carlosan. It was more of a rant.  I have cooled down and will explain a bit better. UDIMs in general is super neglected in 3dCoat. We use them in Houdini, blender and Maya. In general, it will be great to see some development to streamline the workflow more. I generally generate uv's in 3dCoat, but since we use UDIMs so much, I moved that over to Houdini. It is super simple to split and distribute parts over a selected amount of UDIMs that we can input. This happens live in the uv editor. My current problem is baking. Someone changed the uv's (3 uv tiles) on a model with painted textures that I am working on. Now I have 8 uv tiles on the model. Some minor topology changes also happened, but the overall shape did not change. I want to bake the textures from the first model, to the new model with more uv tiles. Simple baking, but the Texture bake tool does not support UV sets or tiles.  It's so old and yet a bread and butter tool for so many fixes. I am now baking it in Houdini, but would like to keep working in 3dCoat as it gives so much control over the maps and painting fixes. There might be workarounds, but this could be so simple if we had an proper Texture bake tool.  

Hi Just tested the latest update 2024.20 - Its says the Surface to Mesh Bug is fixed, but i get the same instability warning and instant crash. I've attached the 3DC file sirf.3b sirf.3b

Hi I am trying to follow your request to give a better answer. So you have a model with uvs and textures, and need to create udims... or have a model with udims and need to paint and bake... Sorry I cant understand the steps you referred on.

Hello People! Long time no see. Im still having trouble with PPP Mode painting. There is this Border created over Triangles. But It is a pure quad mesh. All the best! PS: I found only solution, with subdivision, catmull on, and hard edges set manually. That makes it go away.

Oh this is confusing sorry. -Yes, Open in External App part is working!  But the "export to" works a little different. It should: 1.ask for a filename, 2.popup in Blender. But it doesn't.
