display normals of mesh face with color

General Forums Blender and CG Discussions
#1

Hi,

is there a way, to display the normals of faces with colors? Using the ‘Draw Normals’ in the mesh tools more is working, but it is not useful for a quick general view with a lot of small faces. If one can color the face in correspondence with the normals would be much easier to recognize!?
Does this work somehow?

Best Regards!
Fab

Try using this texture mapped to the objects normal coordinates with an opengl texture preview.

GLSL support is required for this to work. There’s a list of cards that support it on the Blender release log.

This thread was not posted in the support section so users cannot attach scenes.

See the Blender wiki for info on using normals as the map input.

you mean this is only to show a color normal map

i know a way to do this directly with nodes

may be it’s the same think and don’t need gsls for this!

i touhg hw wanted to see more color per normal
but if it is the standard normal color then it’s ok i guess

Thanks
