Relation between texture resolution and render resolution?

[leigh]

The texture resolution should at least match the resolution that it will be showed at in the final render. So if, for example, a section of a texture is going to fill that entire render of 1500 x 2100 pixels, then you need to ensure that the texture is large enough to ensure that the particular part of the texture filling that space in the render is going to be equal, if not higher, to that size.

Thanks for that. Since I'm planning on splitting renders into tiles and rebuilding in photoshop, I think I'll render a few flat-shaded versions and make some measurement notes of the various sections before texturing and work from there.

That's a good idea. Ideally, textures should be as large as you can make them - this ensures crisp, unpixellated details, even when viewed up close. Essentially, the textures should never be viewed/rendered at a distance that zooms into the texture, if you know what I mean.

I tend to paint textures at 2 times the final screen resolution (as in, if the object will take up the full screen, the texture should be twice as large as the screen resolution). I do this mainly because it gives you some leeway if the object ends up getting closer to camera then you expect, and also you can always make low res textures from the higher res one, for example, keep your psd or whatever at 2 times the size, but the actual texture being used in 3d you can size down to the correct size to save on texture memory, but you always have a more detailed backup texture.
