[Opensg-users] Rendering with transparency, second try

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello, forget about the last message, I accidentally sent it before I finished writing ... &nbsp; I achieve some strange rendering effect with transparency that I do not understand an hope that somebody has an idea. &nbsp; I modelled a tree, using a commercial software. The tree has a couple of thousand leafes that are just polygons with a texture on them. All Polygons belong to the same object. The texture uses transparency. The transparency should be thresholded and so either be 1 or 0. I use the dds image format, so that I can control all different mipmaps. When I load the tree into VRED it looks like leafs, that are further away (sometimes) seem to occlude leafs that are nearer to the eye. I do not understand what is going on. For me it looks like the depth-buffer is tricked?? &nbsp; Has somebody an idea what might be going on and can give me a hint how to&nbsp;solve this problem. Kind regards, Bjoern
