Yes, this would be of interest to me also. I have Torque Advanced and though it looks great, I like 3DGS much better. Besides, they have been working on a level editor for 2 years or more (Constructor) and I really like WED

On the forecast page it looks like they are working on a Normalmapping shader for 3DGS. In my dreams, when this shader is complete, it will allow you to apply normal maps to level geometry (that is at least in the BETA version where geometry is actually compiled as MESH) and take the shadowmap into account. It would also be great if this worked with a specular map. I see people asking for this kind of shader all the time.

Lots of other working shaders are available on the forums even very nice post processing shaders, but I'm sure you have seen these. Its just the normal mapping that works with world geometry that I'm hoping for. I know that this would be very slow with BSP blocks, so really this shader would be for the next generation level geometry and models.

The shader editor will also be very useful. I'm looking forward to seeing this.
