--- Comment #13 from H. Verbeet hverbeet@gmail.com 2009-05-04 03:02:06 --- I'm fairly certain this is because of a lack of vertex blending. That is, faking the return value for MaxVertexBlendMatrices in IWineD3DImpl_GetDeviceCaps() should make this work. A proper fix will require implementing vertex blending using shaders.
