2 normal maps per model ?


Recommended Posts

Now that I think of it. there is a workaround here.


1) Take the low-poly mesh and texture it with the tiling normal map only in blender and bake the result

2) Unwrap the UV and now you will have a convolved version of the tiling normal map

3) Make a material with the addnormals keyword pointing to both the baked high-poly normal and the convolved normal


Hope I'm not repeating anything described above.


Of course, you won't be saving anything in terms of texture resources.

Ah right, that sounds like the solution. If the normalmaps overlap they could be merged, which avoids having to use the addnormals line.

      Anyone have any luck with light.setShader( string ) ? It seems to make whichever light you apply it to full-bright on the initial invoke?

      Don't you hate it when there's a quality discussion on a forum somewhere online about something, but then two disagreeing users derail and transform it into a back-and-forth poo slinging competition at one another?

      After watching the first three and a half episodes of "The Sandman" last night, I realize once again that overly imaginative narratives are not for me. Also, the main actor looks like he has a toothache.
      Which makes me wonder, is there a Dark Mod mission with a medieval dentist?
