There are objects with transparent textures - part of visual model or 3d instruments. If two or more such objects overlaps, there is wrong appearance. Objects behind transparent texture may disappear or lost transparency. Some models from CVS has this effect (artefacts with windows, propeller disk etc). I can't find documentation about it.
I found, that appearance of transparent objects depend from sequense this objects in ac file. But there is no methods for control of object sequence in 3d editors (like ac3d). There is simple issue - swap objects in ac file by text editor. Ac3d have simple and well documented format of file. Order of transparent object in ac file must be "from rear to front". For example, if object A stay behind object B, then object A must be placed in ac file before object B. I don't know, if wrong appearance of transparent object present in OSG world, but PLIB version is. -- Wbr, Yurik ------------------------------------------------------------------------- Take Surveys.
