Irregular texture sizes

coldwolf

How do you make eg 256x512 textures? The problem is that when I create a texture that size in Photoshop, max stretches the 256x512 to become 512x512 because the UV space is 1x1. How do I change this?

I'm sorry for the dumb question but I can't find the answer on google or this site. I think I'm using the wrong terms.

Thanks for your time!

Arrange your texture over two uv 'squares', and then scale it down so it stretches in the 1x1 properly.

Or go into the Advanced Options in the Unwrap UVW window and set the "Render Width" and "Render Height" to 256 and 512 or whatever. I believe there's also a checkbox there for "use custom bitmap size", if you use that then when you select your diffuse texture as a UVW Unwrap background image (the drop down near the top right of the Unwrap window), it'll automatically scale the 0-1 range to the correct aspect ratio.

IMHO this is much more straightforward than arranging over two squares and scaling down.

i have a tutorial on my site that describes how to do this pretty easily and has good results.

Yes, it worked Thanks for forcing me to download that Chuggy uv tool thing, it's pretty sweet. Cheers.

Edit: Could someone please tell me how to get the UVs into photoshop as vectors?

Try PSD Path Unwrapper from that page.

i got another question, how do you scale down the UVW
maps? i'm forced to use normalize clusters, which is bugged.
i'd love to set the scale to about 1/5th of the UVW space,
it would save time that i'd otherwise spend scaling down, and correcting the unfold mapping stuck corner bug.
and as a bonus, i'd get UV spaces that are perfectly aligned to eachother.
unfold mapping is very helpful when unwrapping primitives, which i do a lot of when creating mechanical models, and UV distortion is non-existent.
besides, the time difference is massive. about 5 seconds with a raw unfold, vs 1 minute with a raw pelt, on a regular box.
since i'm mostly working with primitives like simple chamfered boxes, and cylinders, this is a massive timesaver.
(yes, i timed it)

e/ disregard this, I misunderstood your question
