I was wondering what bit depth is used generally for textures in film production.
It really depends on what renderer you’re using, but most of the time 8-bit files do just fine. Higher bit-depths are generally used for other channels, such as luminance, etc., and not for the color itself of that given pixel in a given texture.
I use .jpg files a lot still for my work, which are converted to .map files at rendertime in mental ray for Maya.
8 bit is fine for lots of stuff, 16 bit or floating point if you’re doing a bump map, really smooth gradients, or are planning on getting really close to the texture.
