Well I am not a unity developer, but I have looked a bit on youtube and how to mod unity, I assume that would be the best place to start. There are a bunch of tool, and things that exist for extracting assets from unity games, and they seem to work with 3DX as well. I suppose what would be nice would be a community mod that provided a way, and documentation on how to add new content, and was updated with new things as the community created them.

This DJ stand is much more compact then the one included with 3DX. I made it as small and narrow as I could, the file includes matching speakers and a modular platform for the DJ. If it wins the contest I'll make the .world file available for download as well.

They did it seems now to just be the rbg value divided by 255.

I think that the issue is that the file format for new objects saved after 373 changed it now has a different header and the color value is also stored as a floating point value. So this program will need to be updated to work with the new file format most likely.
