Getting post_filter_reflection to work

[carl.sutton]

Hello, I'm having some problems with post_filter_reflection material;

 

What it should look like (from the docs)

https://developer.unigine.com/en/docs/1.0/content/materials/postprocess/post_filter_reflection/reflection_sm.jpg

 

What I have... 0_o

 

Any clues as to where I may be going wrong with this?

post_filter_reflection is not the same as a fair reflective material on the floor. Basically, it is just cheating (reflection is calculated in steps), but it has two indisputable advantages:

• The mesh does not have to be planar to create 2D reflection. It does not depend on the UV map, so it can be any arbitrary shape.
  
• It does not depend on the number of reflected objects (while a fair reflection does).
  

I'm sorry if a picture in the docs is a bit confusing, but post_filter_reflection is designed to work together with normal mapping! (Take a look at the ceiling). A normal map will mask this graded look.

 

If you want to use this material on mirror-like surfaces, you'll have to tweak Fresnel parameters so that reflection is not seen from above. Here's an example of that in attachment.

Thanks for clearing that up. I will have to stick with using toggleable dynamic reflections in scene as there are too many scenarios where this post process will not suffice.
