Hello there Fellows!
I have a question/problem with generating a 2D normal map out of a 3D model. I used Blender for about some months now and everything worked fine up to now. Until now i always used my models in an selfwritten 3D OpenGL engine but this week i wanted to start with a little 2D project. Still, i modeled my artwork with blender so i could generate normal maps and use them for a little lighting computation in my 2D game. But i’m not able to generate it from a rendered screenshot, only off a UV-wrapping texture, which is quite unpleasent because i also want to use the same picture as sprite.
I tried to follow this tutorial for example (https://en.wikibooks.org/wiki/Trainz/Creating_Normal_Maps_with_Blender) but it didn’t let me get the normal map as stand-alone image.
TLDR: Make Orthographic top-down picture of 3D Model to use for 2D game. How to get same picture as normal map?
