[osg-users] Normal Mapping using Dynamic Cubemap

Hi Sebastian,

I believe copying and pasting code is not the case here. I have read a lot about MRT, RTT and FBO and debugged some source code examples (including your hints), however I still have problems in my side to compute the normal.

So let's go to new doubts:
- In Kapelko's example, if I disable the bumpmap use, why is the normal still computed by using the TBN matrix (please see [0])? Why the nn is set to vec3(1.0)? In addition, why one of the walls does not contains data (green channel is missing?) - please see attachment?

Thank you!
