Controls in the Textures tab let you specify how to handle texture files in Arnold.
|To minimize memory consumption, render times and network stress, it is strongly advised that you convert all your textures with maketx to linear, tiled and mipmapped .tx textures.|
Automatically generates tiled and mipmapped TX textures. The TX texture will be linearized according to the colorspace parameter.
Allow HtoA to use pre-defined .tx files, if they exist.
