Week 9 Bump mapping texture

This week I focus on how to create a bump mapping in Ps and insert it to Maya scene.  I find Stuart Christensen’s online tutorial which is http://www.youtube.com/watch?v=bxWsgm4p77A. It’s very helpful.

This is the screenshot for this online tutorial.

I learned how to create a bump map in Ps in two ways.

The first one is: download a high resolution texture online and place it into Ps. Duplicate the layer and click Image menu and find out adjustment and then choose Desturate to make the high resolution picture to black and white one. For more details, just change the bright/contrast or levels.

The second way is using Invert to change the positive and negative values.

The most important thing I learned in this online tutorial is that for best results, use high resolution images and keep everything matched. Maya loves 2048*2048 or 1024*1024 size textures. But smaller sizes will work well for really small surface.
