when working with some 3D models visualization in Processing 2.0b8 I noticed that all models loaded from obj files seems to be rendered with a blue light and, if no texture is assigned, instead of materials specified inside .mtl files they catch a light blue transparent material.

For example if you try the Examples -> Basic -> Shape LoadDisplayOBJ you'll notice a blueish color on all model and if you comment the line with rocket.png of the mtl file loaded inside the rocket.obj you get a semi-transparent blue material by default...

This doesn't happen using 2.0b7 where the rocket appears all grey and opaque.

Am I doing something wrong or am I missing some important change made in Processing 2.0?

Or we may have an issue here...

Someone can confirm?
