I've recently bought a bumpmap head and for the life of me can't get it to work.

I've tried everything, tweaking every option, uploading in all supported format, tried both gray scale/normal texture/blue map but nothing works.

Here's everything I've tried:

*Tried all formats - png,bmp,tif,tag and jpg

*Tried all options - shaders on/off etc

*Tried multiple pixel size - 128x128, 256x256

*Tried Grayscale, Blue map, standard textures, alpha textures...........

*Tried turning off normal head texture with only bump head activated

*Tried turning on both head textures.

At the moment it doesn't seems bumpmap does anything for me. Please help.
