3Delight automatically optimize textures for rendering. The optimisation process consist of creating a mipmap version of 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. These optimized textures are stored at the location specified in the 3delight.config configuration file.
The texture optimization processes takes care of using the proper color space assigned to the texture. Color space assignment depends on the source of the texture:
| Source | ||||||
|---|---|---|---|---|---|---|
| Maya | Renders started directly from Maya, or from NSI files generated by Maya will use the Color Space that is used in the File shading node of the source texture.
| |||||
| Katana | Floating point textures (including 16 bit halfs ) are considered as linear, everything else as sRGB. This is also the case for NSI files generated by Katana. | |||||
| NSI file | NSI files will generated by other means than 3Delight plug-ins can still take advantage of automatic texture conversion. To do so, there should be a special attribute accompanying every string value that points to a texture file. Here is a simple NSI example:
The "textureName.meta.colorspace" indicates the color space for the texture designated by "textureName". Any available OCIO color space can be used. In addition the following presets are recognizd: linear, rec.709 and sRGB. |
You may consider preparing textures manually using the tdlmake tool for these reasons:
