I tried with just Bumpmap, but seem to that I have bit problem with the bumpmap file. I used photoshop and I turn the texture to Grayscale , but I think its not enough or maybe its not the right method to create bumpmap.
Anyone here knows how to create right bumpmap or how can you tell its right bumpmap for the texture? is just grayscale enough or do I need more tweaking?

Crazy bumpmap is down, plus they don't have Mac version.
any other idea?

please link or any suggestion.

regards
