CryingWolf - "I like fact that when you export from LeoCAD, and import in brice that the model is a group of individual bricks. You can then do alot of post work in bryce." That is right. But that also makes it diffucult. A technicsmodel consists of hundreds of pieces and assigning materilas and changing settings on each and every of them is a real hassle. Selecting them and grouping them in Bryce is hell aswell. I found a way of exporting the LeoCad models grouped by color and I also use a trick that makes the different color groups fit perfectly when imported to Bryce. I'll make a couple of screenshots and post them here along with an explanation.
