Off topic a little. But I have seen you on different sites and your knowledge seems strong.
I am new to 3D modeling and have a lot to learn. When I render a model I have made in 4D lite it shows concrete with great detail, but, when I render and/or export in AE it just sows as a gray surface. Do you know what would be causing this, if it is the way things are and do you know a work around?
Can you show us some screenshots of what you're talking about? My guess is that it's using the hardware or preview renderer instead of the final renderer.
