This tutorial uses a simple scene of a wooden floor to illustrate the benefits of using maketx to preprocess your textures.
Approximate time for completion: 25 mins.
To get the best from Arnold it is strongly recommended that you convert images to tiled, MIP-mapped textures. High-resolution unmipped texture maps are very inefficient to render, because the highest resolution level must be loaded into memory regardless of the distance rather than a lower resolution level. Likewise, untiled texture maps are also very inefficient because they must be loaded entirely into memory as soon as the renderer needs to access a single texel. By the end of this tutorial you will be able to reduce the render time by less than half.
A quicker way to convert textures to .tx is to use the TX Manager.
