Texture resolution - query

roboy

Hi all,

Not sure if this should be in the "technical section" but I hope you can answer this question.

If I had a limit to just use a 1024x1024 texture on an environment, is it acceptable to create 4 separate 512x512 textures and scale up the UV maps?

The reason I ask is because I want to use a tilling brick texture without having too many seams, the only way I can get around this is by either using the whole 1024 space or by using a dedicated 512 texture for the bricks/asset.

Thanks in advance!

yes.

You could even break it down farther if you wanted to, from 4 512s, to 16 256s, or, any combo of that.

What does your graphics programmer say? If that's you... I'm sure its ok.

Thanks for the reply - wouldn't it be more resource hungry if you had to load 4 or even 16 textures (256s)? I imagine it's more ideal to only load 1 texture per piece but of course the resolution would play a part of that also.

And no graphics programmer.. this is just a personal question/work piece

more textures = more drawcalls = slower rendering

He doesn't mean seperate images, he means seperate quadrants of the 0-1 UV space. Meaning you're using 1 1024x1024 image file.
