The optimization process consist of creating a mipmap version of source images that can be used efficiently as a texture during rendering. This process is important as non-optimized textures (without mipmap) can slowdown rendering significantly.

For the automatic optimization to work, the texture directory or directories where the source textures are located must have write permission not only to oneself, but to other users as well (so the optimization process to works for them if needed while rendering). The source textures themselves do not need to have write permissions as 3Delight only access them for reading and never modifies them. |
