The Textures group of controls lets you specify how to handle texture files in Arnold.


Tx Generation

Tx is a tiled and mipmapped texture format, which will dramatically improve time to the first pixel, overall render time, and memory usage. Therefore converting textures to Tx files is highly recommended. You can choose your preferred workflow of generating Tx textures:

-u --unpremult --oiio (--colorconvert [image_space] [render_space] --colorconfig [config]) (--format exr -d half --compression dwaa)

Accept Unmipped

Auto mipmap

Accept Untiled

If a texture map file is not natively mip-mapped, the render will give an error unless this option is checked.
