Quote: "IrrEdit is a scene-graph editor made with and for Irrlicht and so AFAIK it only exports to .irr which is Irrlicht's scene-graph file format, and it may be difficult importing this into DBP."
Actually it exports .OBJ, .XML and .DAE as well so it really would not be too difficult to convert these.
I've looked into and tried out the freeworld3d myself. From what I see, it is not different then T.ed, The main purpose is for terrain and environment setup. Problem is the demo lacks textures and what not. so testing it is somewhat useless. Personally before I buy this software, I would want a simple demo that could be loaded in dbpro so I would be able to see if what im buying is going to be compatible.
You could also try Deled, They are expecting to release version 2 any day now. Version 2 I guess is going to be a feature update with some very useful tools, they have added simple animation to the package, which is going to be rather handy for animating things like doors, windows, ceiling fans and so on. However, although it is bone based animation, it will only be basic animation and does not have features yet such as weight painting. It is going to be best used for mechanical animation.
