Weird red/green artifacts on normal map

posted to: Baking the Normals

I follow the workflow to bake normal map, but weird red/green artifacts appear on some objects.


Red/green artifacts.

And the baking time could take hours for 1 cube object as above.

Have I done anything wrong in my blend file?

    I fixed the normal map by recreating material, image texture and unwrap once again.

    Still I have no idea why previous one didn't work. Pretty sure the workflow is the same..

    Wow, I downloaded the scene and it does take hours! I'm glad the red / green issue got fixed by recreating the material, but could you please chime in to this bug report so that the normal mapping time might get fixed?

    Thanks! It'll be smooth sailing from here once you're done with the normals. Happy texturing!
