During rendering, whenever 3Delight encounters a non-optimized texture, it will create an optimized copy automatically. The optimized texture will be saved at the same location and will have the same base name as the associated non-optimized 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). Note that if some source texture changes, it will be automatically re-converted.

For the automatic optimization to work, the directory or directories where the 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 non-optimized texture files themselves do not need to have write permissions as 3Delight only access them for reading and never modifies them. |
