Decals not appearing in OpenGL

[Daniel B. Chapman 20]

I'm trying to render some paints over a glowing texture (basically simulating paint on a frosted surface that has back-light on it) and it is working in Renderworks. However, when I view the same objects in OpenGL I end up with a blank surface per my second image. 

 

Is there something I'm doing wrong? Decals seem like the right approach for this workflow and I would love to be able to set them in OpenGL rather than swapping to Fast Renderworks to set position as it is, for obvious reasons, a faster workflow.

 

Any help would be appreciated.

Decal Textures will not display in OpenGL. Our OpenGL implementation is only capable of displaying one texture per surface. This is something we will likely improve in the future with the inevitable replacement of OpenGL tech, but this would be a version or more away.
