Yes, but the floor mist is what I'm trying to achieve and the only way that I have found to do it is with heterogeneus participating media.

With 0.0 IOR I get this result: edit 1.0, but the image is correct

I was trying to get some mist like this: normal_un-arbre-seul-dans-la-brume.jpg And I get this material: MIST.jpg As you will see at the base of the sphere the mist material is almost transparent, that's because the paper es above the sphere's base, but the material should be volumetric And sorry fo...

I mean the corner that seems like a portal to another world

I was experimenting with the precedence setting and i get this strange image: Blender shot:

In general, you can't divide vec3's, only real vs real

Yes, but you can't divide a vec3 with a real.edit:And thanks for the optimizations.

Overlay: isl_camo_overlay.jpg <![CDATA[ def overlay(real it1, real jt1, real kt1, real it2, real jt2, real kt2) vec3: vec3(div(mul(div(it1,255.0),add(it1,mul(div(mul(2.0,it2),255.0),sub(255.0,it1)))),255.0), div(mul(div(jt1,255.0),add(jt1,mul(div(mul(2.0,jt2),255.0),sub(255.0,jt1)))),255.0), div(mul...

Thanks Fused, it works!
Now I'm doing overlay, screen, etc
edit:: I think blending modes can be bundled into exporters.

Yes, but it can be easily converted from 0-255 to 0-1. I'm testing...

I mean tex1 (r1,g1,b1)/ tex2 (r2,g2,b2) = result (r1/r2,g1/g2,b1/b2)

I'm working on a shader that blend towo textures with the "burn" equation. The problem is that I need to divide two vec3's and Indigo doesn't have that feature.¿Someone can help me?
I = Top Layer
M =Back Layer

One of my meshes have an accent in the name.Fixed.
edit:@ben, I have windows, as mentioned

blendigo 2.2.1; indigo 2.0.12 for windows 32bit

I have a strange problem with the exporter.
