mantraSurface shader. Export refraction

[rcwork]

By the way... one more thing about strange permutations inside "MantraSurface"  

I have found a very big difference between directlight node for H12, and directlight node for H13 (i do compare because i remember another results with H12)


- - - 

and few words about impressions by "Env Light".

 

It a really mind blowing, when you has empty "Reflection and Refraction" fields on "obj" geometry level, but object still get reflections and refractions from Env Light

- what the problem of this ? When you want to correct some reflections, or refractions, you can use planes+constant, visibly only by one object. You can use 1,2 or 5 planes and get nice look. With new H13 pipeline, you will get the same, but not the passes from that reflected planes. Using Env Light for same job - really strange workaround.

 

I think, finally, is really only way, when you need to get proper passes - is creating you own shader. 

 

Another question, what about some productions-ready shaders for houdini ?

With simple getting of Refraction, Reflection, Diffuse, Specular passes ? Is exist ?

But    !!! 
In real photo studio setups, you always use real lights. Or surfaces tinted by lights.  
From this side Houdini lighting way is absolutely logical.

Check out the Orbolt page.  I've heard good things about the PBR layered one.

A lot of thanks, marty. This shaders looks awesome. And reasonable priced..
