Udim/tile limit?

[Maak]

Hi There,  

I've got the demo version of 3dcoat at the moment and was looking to bake maps for some large assets.  

Every time I try to load the obj in I get an 'square of the uv set is too big' error.  Is there a limit to the amount of tiles you can bring in?  

Most of the assets I'm working on are around 70 or so tiles and sometimes up to 200 udims/tiles.  Before anyone asks, yes, I do need that many tiles   Sometimes the camera is rubbing up against the asset.

Cheers,

Mark

Hi! Welcome.

This happens when you don't have "Import Tiles as UV Sets" ticked on in the import prompt. It is caused by having something outside of 0-1 in UV space, so ticking that option should look at the tiles and import them as you're expecting.

 

PS - I hear you on needing lots of UV/UDIM tiles.  It's just the nature of the work.

Thanks for the reply, 

The warning comes up as soon as I choose the model.  When I do check 'import tiles as uv sets' and carry on my machine freezes up.  I guess it's running out of ram?

Any chance you have some floating verts or 2 point polys? What application are you modeling the asset it?

Had to register just to share my solution.
 

The problem seems to happen when you have another UV channels that are not properly unwrapped.

In 3ds max add modifier UVW Mapping Clear and choose Map channel: 2. This will completely remove second UV channel and model should import correctly
