What's up with the Marlin materials in the Bitmap Plus materials on the svn? Most of them are blank.

When they were made, there was still a bug that caused the image path to not be saved. This was corrected in a later alpha...
The images are in the same directory, you will have to load them and then resave the material. The images and material have the same names--there is a color image and a normalmap image for each.

Ah. Thanks Will.
