Non-Proportional Textures
-
25 Apr 2010I was just wandering... everyone talks about using only square textures (2k, 4k etc) and i have been using this so far. Everywhere I hear about using only square textures i hear that they are best and game engines can read them good.
Since i am not really interested in game engines i was thinking about non proportional textures. like for example 4096 x 1024. Can i use those types of textures? Without any drawbacks? How do i export an rendered UV from max? More important question is how do you pack a non proportional texture into UV space when doing the UV-s and so on.
I could really use non proportional textures sometimes like for example a portion of a road, I don't have to slice it in half to make it fit better into the UV space.
Can anyone shed some light on this matter? Some links/info? Or better yet personal experience?
Thanks! -
25 Apr 2010you can definately use it in max. I guess maya has some problems with that (not sure what it was but our maya crack here always said they have to be square).
i dont know if there is any drawback on that. -
25 Apr 2010Yeah i can use it if it is only going to stay in max. Thats a serious limitation.

Jonathan 480 posts08 May 2010In video games, they aren't an issue either normally (at least not on current-gen hardware and newer). Long story short, they're also sometimes desired, as sometimes, for example, in a normal map, you'll only need certain directions/vectors, so one axis can have less information than another, and reduce memory usage, etc.

08 May 2010I doubt there's any limitations on whether it's proportional or not in any software... certainly not in Maya. It really depends on what you want with the texture and where you are using it. I mean, if you have a cube that needs a texture then you use a texture that's square. If you have a background matte and your output will be 16:9 then you'd use a 1920 x 1080 (or whatever is 'proportional' to the output). One thing you don't want to do is have some shape that is 4 times longer than it is wide and put a square texture on it - doesn't make sense. I think the square tex thing is more for textures that you want to repeat, since it's just easier to manage with a square image.

09 May 2010I was talking about textures. The custom painted ones. The ones that you UV a model and render UV template and do texturing in photoshop. Thats my consern. You need to render square templates right? Or not? Can you render an 8k x 1k template? Even if the 0-1 UV space is square?
