Lovely :3
I'll let the pictures do the talking initially.

Render from 3ds Max (how my vertex blending should be looking).

How it's presently looking in Irrlicht.
The MaterialType is set to EMT_TRANSPARENT_VERTEX_ALPHA, with lighting disabled and gouraud shading enabled. You can't see it as clearly, but I'm also having a similar problem with the vertex color blending on the doorway, the fade to black from left to right should be happening front to back. I'm completely stumped.
