How to use world-normal-map in shader-node?

09 June 2016 23:23 #10045
Hi @ll,

I want to use a baked world-normal-map of an object as a vector source for an environment-map (shader-node-material).
Is there an example of how to convert the texture node output (value range rgb 0..1) to a well formed directional vector (xyz -1..+1)?

Saludos, Daniel.

Hi, Daniel.

Are you talking about those texture that's used on a world as "Environment Map" like described here:
https://www.blend4web.com/doc/en/lighting.html#environment-map-method?
This functionality doesn't relate to the node system, so, are you planning to bake env map somehow from a normal-map and use it later as a world's texture like usual env maps?
