This works great as long as there is no uv mapping assigned to the model. But if the model (created in MED) was skinned with the "6 side mapping" tool of MED, the defomring doesn't work: This is how it should look like: It seems like the mesh was splitted through the skinmapping. Maybe this is because every vertex occures 3 times in the uv mapping (one vertex is shared by 3 sides of the cube and through the 6 side mapping every side is seperate in the uv mapping): What can I do to overcome this problem? Do I have to update the uv mapping (btw. how can I do this)? Thanks for your help! ANet - A stable and secure network plugin with multi-zone, unlimited players, voip, server-list features,...

My theory: A vertex can have only 1 uv coordinate. But the uv mapping created with "create 6 side mapping" needs at least 3 vertices per "real" vertex because otherwise it won't be possible to split the sides of the cube as shown in the skin editor screenshot. But I think the 2 additional vertices are somehow hided by the engine and not returned through ent_getvertex(). Thus I can only change one of those vertices which leads to the strange behavior. What do you think? ANet - A stable and secure network plugin with multi-zone, unlimited players, voip, server-list features,... (for A7/A8)! get free version

All vertex that occure only 1 time in the uv mapping also work for me (you only try 1 vertex so maybe you had luck). Could you upload the model if the error still doesn't occur for you? Thanks Btw. if I want to create a mesh that has seperated sides like in the skin mapping screenshot, how would I have to do that? I see no other way than creating the same vertex more than once (because one vertex can't have different uv coordinates)? Last edited by Dark_samurai; 02/11/12 19:28.
