During rendering, wherever 3Delight encounters a texture that is not already optimizednon-optimized texture, it will optimize it automatically. Such The optimized textures texture will be saved at the same location and will have the same base name as the source texture. associated non-optimised texture, but with a .tdl extension added. This process will skip any texture that have the .tdl substring in the file name (e.g. texname.tdl.tif and texname.tif.tdl will be considered as optimized).
| Warning |
|---|
For the automatic optimization to work, the directory or directories where the source textures are located must have write permission not only to oneself, but also to other users (so the optimization process works for them if needed while rendering). The source textures non-optimised texture files themselves do not need to have write permissions as 3Delight only access them for reading and never modifies them. |
