Same texture, but different..
 

I want to have a model with one texture that can be swapped with another using model.texture("new_tex.jpg"). When swapping back I noticed that the new "first" texture was much darker than the original.

I have attached a scene with two cubes which demonstrates the problem.

What is happening?

I tried adding a cube without any textures, thinking maybe the original texture blended with the new original, but then it turned completely black. I also tried playing around with model.appearance() and texblend, but to no avail.

Doesn't anyone have a clue as to what is going on?

The cube uses negative values for the texture coordinates. This means you need to enable wrapping on the texture. Try using the following code when adding the texture:Vizards default wrap mode is viz.CLAMP_TO_EDGE, which does not allow for texture coordinates outside the range of [0,1].

Yup, that was it. Thanks a bunch!
