What was the issue? Lots of noise?
Yep
Noise with glossy transparent should be improved now, hopefully.

Wow!! Thanks Ono. I hope to have some time to try out all of the new shader functions but it may not be soon. :( I have been very busy and I'm in the process of purchasing a new house, so no time to do fun stuff. I did have one question, could you tell us what Indigo can pass to the shader function? I didn't see much in the manual unless I missed it somewhere. I am particularly interested in seeing if Indigo can or will pass the surface normal vector and the incident ray vector to the shader functions. Thanks again and great work!!

Hi Grimm,
right now the shaders can only access the hit position in world space, and the UV coordinates at the hit position.
I'll likely add access to the geometric and shading normals in the future.
I'm not sure about allowing access to the incident ray, there are some issues with such access.

global texture mapping? :D does that mean you could define a texture that uses world coordinates for mapping?

Cool, thanks Ono. Is the issue programmatic or is it a problem with the shaders changing the incident vector? I would be fine with a read-only view of the vector if that would be better. 8)

Is it just me or are the caustics WAY faster in this release?
I was rendering a pic with 1.1.10 before and now upgraded to 1.1.11...
Didn't have any caustics in the 1600spp render from 1.1.10, in the 200spp render from 1.1.11 the caustics are clearly visible

Sure, but texture coordinates have to be 2-d (for 2-d textures), and the world position is a 3-vector.

Working with just the incident vector won't be possible, because the BSDFs have to be reciprocal to be physically plausible. But it should be possible to have physically plausible shaders that depend on both the incident and reflected vectors.
I won't allow the reflected vector to be changed, though.

hum... and what's about chainging the incident vector with limits, based on the reflected vector? ^^

ono I guess 'rectanglelight' is also deprecated? - if so should note that in the manual ;)

Oren-Nayar does not support layers (and emission ?) !
obsolete asset
