I am trying to get normal mapping figured out because I
think it will enhance my material substantially. I am using Nvidia's Normal map plug-in in Photoshop.

 I have created a
normal map in Photoshop and now I am trying to add it in the bump channel and
it does not seem to be changing anything. I have included a photo summery of
where I am at. The upper rendering is with the bump unchecked and the bottom
rendering is with the bump checked on at 30%. I have a diffuse bitmap of the
tile at 100%. Thanks in advance for your help.

TRY!!! IN DIFFUSE MAP CHANGE TARGA TO JPEG AND THE BUMP MATERIAL SLOT CHANGE ALSO IN JPEG....LET SEE WHAT HAPPEN YOUR OUTPUT.....BY THE WAY IM WORKING IN 3DMAX AS A VISUALIZER HERE IN DUBAI.....
