Click to turn on the options. A check mark displays if the option is on and the option you select will be enabled during output. The checked domains will be filled with the material attributes.
These options determine what elements you want to export and how to export them.
Uses convertSolidTx to create image files for both file and procedural textures. If turned off, Maya reads in the file textures as they are, and only converts the procedural textures.
Uses the 2D texture placement transformation information to generate the file image for output. For instance, the checker texture image consists of a checker board of 8x8 checkers. If off, the UV repeats are set to 1 internally, UV Rotate is set to 0.0 internally, and then the texture is processed. The result is that the checker image will be 2x2 (assuming the default 4 repeat).
