Bake tangent normal map

Recommended Posts

Hi again! keep testing 4.5 version of 3D Coat... looks great! The only question i cannot find anywhere is which preset i have to use for baking tangent normal map if im going to use it in Maxon Cinema 4D for final render ? Everytime i bake the tangent NM i get very strange result with a lot of black areas :-\ 

When i use the normal world map its going great without any weird bugs!

The "black areas" are the result of misapplied "Scan Depth" settings. Preview the inner shell to see if there are places where it's showing through and the outer shell should completely cover every thing.

Thanks, Mr. Tony Nemo. But "scan Depth" settings are good  enough. Problem is the only tangent normal map gives me bad render in Cinema 4D (img posted below). Others like Normal world or bump  maps - give me decent result!

Okay, actual blak patches were what I thought you were dealing with which are scan depth issues. Tangent World giving good results in C4D is a useful tip, thanks.

So in my case the only way is to use the Normal world map to get clear render, right? or there is some solution ? maybe another preset for baking?

That could be the result of vertex normal map. Does that mesh have one?

No, Mr. Javis. There is no vertex map on this object. Only the "phong" tag. By the way, when i use the normal world map the "phong" tag doesnt affect the render result. But when i use tangent normal map it does! 

The "phong" tag depends on a splay angle between polygons... i hope it makes sense...
