* Passes renamed to samples * Camera lens radius renamed to aperature size/blades/rotation * Glass and fresnel nodes input is now index of refraction * Glossy and velvet fresnel socket removed * Mix/add closure node renamed to mix/add shader node * Blend weight node added for shader mixing weights There is some version patching code for reading existing files, but it's not perfect, so shaders may work a bit different.

/* not particularly proud of this massive switch, what are the

alternatives?
|
|
- use a single big 1D texture, and do our own lookup/filtering
|
|
- group by size and use a 3d texture, performance impact
|
|
- group into larger texture with some padding for correct lerp
|
|
|
|
also note that cuda has 128 textures limit, we use 100 now, since
|
|
we still need some for other storage */
