I need help...


So I got my crab dude into Mudbox and damn if I have him almost out. I really don't know what Im doing when it comes to bump maps. All I can find on the nets is to turn from "bump" to "Tangent Space Normals" but that doesn't seem to change anything. The strange thing is it looks good in the viewer but when I do a render the bump gets way to intense. I have other problems like the seem down the back of his hip and the fact that I get an error every time I try to extract any part of his tail as TIFF but not problem if I do a JPG. The rest came out fine. I wanna get this guy done but damn, HELP me please!

Thanks in advance for any help or just a point in the right direction.

regarding the reversed normal map. well it seems only to happen when the uv's of the other half are over-laid on top of each other... textures.. of course don't get affected in that way. i hope it helps some. when playing with the normal maps in rendering.. well its gonna be a lot of trial and error. as i had the same issue before. i never really got a fix for it. i just had to tone down the intensity of the normal map displacement effect and kept re-rendering till it looked good.

Well Thanks to the power of MATT I have fixed the main problem. It seems I need to be rendering with mental ray to get the clean look that I got in the viewer. I may need to jump into photo shop to fix my seems.

Excellent! I was getting the same results as you (Kenny) when testing a random normal map. In maya, the HQ mode was correctly displaying the normal map, but the the maya software renderer continued to produce images using the normal map as a bump map. Something to do with the renderer settings. Merely switching to maya hardware corrected the problem, so I'm still not sure what the incorrect setting was.... :)

oh I wanna see Tony's new renders.

My New big problem is Mudbox's baker. Any time I try to bake a TIF I get an "unknown error" or a TIF file with no image. Before I'd have to bake a jpg and then bake a TIF to get the TIF to work.(don't ask me why I have no idea it just seemed to work) I'm down to the tail now but nothing seems to get them out. Im going to the DP today to see if it some how will work there.

So I found out the problem with the "unknown error" it seems to really be a "not enough virtual memory error" though thats not what it says. I think this because when I baked a 16bit normal instead of a 32bit normal I had no problems.
