View Full Version : normal maps on a mac

09-07-2003, 08:50 PM

I'm new at modelling/texturing working with wings 3d and Motionbuilder. I need a normal map of a texture to be able to generate a bump map in MB. I've been doing reading about ATI's normalmapper, ORB on this site. Given my lack of experience it's a little daunting although I think I understand the basics as it relates to adding a more realistic texture to a low poly model. I'm beginning to think though that maybe I'm dealing with two different issues here and was wondering if someone could help me. I see Nvidia has a plug-in for photoshop that will create a normal map. Since for MB I need a normal map of a texture that isn't necessarily currently on a model, is it really the Nvidia type of normal map generated in photoshop that I need. My more basic question is whether the Nvidia normal map creater is actually a different beast than ORB and normalmapper since photoshop is obviously not able to determine the slope of normals since it's not a 3d programme. My ultimate question--if I need a texture to be a normal map (xyz info in the rgb channels) what's the simplest way of doing this if I'm on mac?

Thanks in advance

Hmmm, I'm not a mac user, but there's a Cinema 4D tutorial that might help. You might be able to use some of the info to make your own shader?

About the nvidia tool, it only works off grayscale images, which are OK, but it does not compare with geometry-based normal maps. Although it does pretty well if you feed it a good-quality displacement-style height map. But then again, you need geometry to make that in the first place.
