David Barbarash Posted September 2, 2003 Share Posted September 2, 2003 A couple of questions first, what resolution are you taking the pictures at? What materials are they? Can you post a sample image (both diffuse color and bump map please.) What is your lighting situation in the model? In the picture? The more information you give, the better we can help.

It sounds like you may be under the impression that a ".bmp" file has something to do with a "bump" map, which is not the case. There's really no reason to convert anything jpeg format to a .bmp file... unless you simply want a lossless file format... in which case a tga or tiff file might be a better choice, or at least they are more commonly used in my experience. Is it the concept of a bump file that is eluding you, or am I missing your meaning? -john manning Link to comment Share on other sites More sharing options...
nevisstudio Posted September 2, 2003 Author Share Posted September 2, 2003 thnx for the response... one of my problem is the roof...i have a picture of a cooper shingle that i need to use as a texture...it is currntly a .jpg 35"x22" 75dpi...my problem is when i map it on the roof it appears very flat with no relief....i have a colored jpg as the image and a b/w .bmp image for the bump...i cant get the image to appear non-2d.... is this any clearer Link to comment Share on other sites More sharing options...

Remember that in the bump map, the whiter the pixel, the "higher" that spot will appear to be raised in the rendered image, and blacker pixels will make that part of the image appear "pushed in. http://www.jm3d.com/bumps.jpg Look at the example I've uploaded of snake scales... notice how the a colored map doesn't always translate into a decent representation of highs and lows. The orange scales become gray, and the black scales remain black...wheras in real life they are at the same "bumped" hieght. Also note that the .bmp format has nothing to do with "bump" maps... that's just a coincidence. Personally I never use .bmp files. -john manning [ September 02, 2003, 04:19 PM: Message edited by: recon ] Link to comment Share on other sites More sharing options...
