@tom_forsyth One interesting thing here is a probably relatively cheap way this could have been done originally was texture-matrix-per-lod.

@tom_forsyth Ie., you could put the sampler in a mode where an identity texture matrix is assumed and LOD is calculated... -
@tom_forsyth ... AND THEN the texture matrix multiply is applied, selected from n matrices, one for each LOD. - Show replies
