Is there a way to resize texture to fit your geometry? Theres probably a straightfoward way that Im just missing.
I don’t know what you mean by resizing textures to fit your geometry.
Textures are measured in texels, which have very little relation to the size of the geometry. If you mean you want to size the texture so that it is approximately one texel per pixel when it will be rendered, then you also need to know how far away your geometry will be viewed, how wide your camera’s field of view is, and how large your window is.
If you’re referring to textures created specifically for onscreen 2-d objects, egg-texture-cards can easily size your textures according to your pixel requirements.
Anything else is probably best handled by the modeling package that you use to create your textures and geometry.
