I was working on my scene today, when all of sudden, Layout UV tool just stopped working properly! It does not layout UV's properly any more. Here's and example: Simple UV unwrap, all the shells are straightened and easily fit into 4k texture with texel density of 13. Now, I open Layout UV tool, click Apply... and this is…
Yes, it just takes the same layout as it did before, but scales it down to fit into the grid: However, scaling changes texel density. I only use scaling when making lightmaps.
Have you tried resetting the settings for the Layout tool? When in doubt, always try that first, to see if it fixes it. Then readjust the settings you know you need adjusted.
Yeah, that seems to be the case. Thanks! Although it's still really weird. That's the first time I've encountered something like this. But I guess the reason why rotation fucks up auto-layout for this mesh will remain a mystery...
Here's another example of what Layout UVs does now: It was set to 6 pixels gap between shells. And some of them have huge gap between them, and some are literally touching borders. :| Why? What happened?!
I chose texel density of 13 because it's equal to 300x300 cm tile with 4096 texture. And this prison bed is about 212x106 cm. I guess I'll just have to layout it manually... I'm out of ideas why maya behaves like that.
The cube layout is fine, it's as it should be - 13 texel density, no scaling, fits with more than enough space left. My scene is set to centimeters with Z as vertical axis. Could you test my bed mesh instead? It's already unwrapped properly. Try to use laout UV from unfold 3d plugin with scale mode and pre-scaling disabled…
It'll be some hidden cancerous shit in the history of one of the nodes that was once involved in creating the mesh Combine it with a cube/export to obj/sacrifice your firstborn and it should sort itself out
I've deleted the entire config folder for maya (after I backed it up, of course), which resets EVERYTHING. And it was still doing the same thing. I have a feeling that maybe it's something with my mesh that causes maya to freak out... But I don't know what. It all looks clean, I don't see anything unusual.
