Merge assets with UV Tiles

[Samuele]

HI,

what is the best workflow to do this? 

merge 2 (or more) assets, that have their own UV tiles(UDIMs) and texture maps, into one.

At the end of the precedure i should have just one asset that should maintein the same texture quality.

Exemple: i have 2 rock scans with their UDIM and, as result, i need just need one rock with its own UDIM.

PS: the assets can overlap.

 

thanks,

Samuele

Maybe it can be useful for someone else:

 

the problem was related to windows file writing permission in c:\user\myname\documents\3dcoat

there was no chance to modify prefs files there due to admin rights...

I've forced deleting 3dcoat folder there with DOS prompt, reinstalled and now all is fine

Hello! The fact is that after exporting from 3Dcoat you will receive one object with two or more UV sets. Each UV set will have its own set of textures. You can try selecting Export UV Sets as Tiles in the export window and see how this set opens in another application.

Hope this help

Thanks for the reply.

 

I've already done "UV sets as tiles" and it works as UDIM in others software.

But what i mean is that:

I need to get a curvature map for the entire asset. If the mesh are just part of the entire object (but not blended together) what kind of curvature map I'll get? One for each object?

I need that curvature map detects where the objects overlap...

Carlosan,

 

the video is interesting but:

-all the UV maps are merged in the same UV space (so they have to be reduced in size). I do not need just one big UV set at the end.
If the starting meshes have 2 UV set each one the final mesh shoud have 4 UV set.

 

-the meshes do not overlap

 

As i mention before I need that the curvature map "knows" where the meshes intersect each other so that, for exemple, a smart material can know how to put some dirt there...

Once you have loaded all parts of your object into 3Dcoat, you can calculate the curvature map. It will match the curves of the entire model.

Where can i find "calculate curvature map"? (In previous versions was in the Textures menu)

Can't find it in the Edit menu too...

Now it is on Edit Menu

[Samuele]

now I understand, I had a bad install on my machine: "calculate curvature map" didn't appear on edit menu.

[Samuele]

I don't know if it is related to this:

but the edit menu appears like this:

 

I've tried to uninstall and install it again. 
I've installed with administrator rights..

Version is 2024.15
