I’ll try make a normal map from a “sculpt” model.
But, how i export the “uvmap” of the combination of material (3 Blendes materials) , in my case i follow the tutorial in http://wiki.blender.org/index.php/Manual/Bump_and_Normal_Maps to make the normal map effect in model (and i can view the model with the normal map lighting, but how i export in uv image window with the lights/colors) ?
Thats is a part of my model (i sculpt only the head in this moment to understand the process and see results in low poly model).
um, no. you should render bake the normals. see the wiki Render section Render Bake. And I am no expert, but I think that low poly head has too many polys -about 2x.
please read note on Ambient FIRST on the Render Bake page. You have to bake ambient first, i think, or one of them, or you get the “No Image to Bake To” error
I think you may be looking to create a tangent normal map which Blender can’t do, yet. It can however work with tangent normal maps via the NMap TS button on the shaders tab. If you’re on a windows machine you might want to try xNormal:
No, you can use blender to make your normal map. And PapaSmurf is right. If you use windows xp, you must first bake as ambient occlusion, then you can bake as full or texture or normals.
If you want to upload the packed blend to www.4shared.com I will look at it for you?
No, as RamboBaby already pointed out, Blender cannot yet generate a tangent-space normal map (which I think the poster is looking for) in any way shape or form. It can generate camera-space or world/object-space maps, but these are only useful for faking relief on flat objects or if the object doesn’t deform.
The render baking option for normals creates a camera-based map, where the colors corresponding to normal directions are generated relative to the position of the rendering camera. Not very useful for animation or games models.
Tangent-space normal maps are calculated based on local geometry (sort of) rather than the position of the whole object or the camera, so can be used on objects that deform. Again, you make these by exporting your model to Xnormal, ORB, or Nvidia’s Melody. Blender can interpret these maps just fine with the NMapTS option, but cannot make them.
BluePapa: Btw for some mysterious reason, I can now render-bake anything in 2.44 / XP without having to do the AO bake first. Works every time now. Go figure.
