I have a mesh here with two materials. Old version of this mesh worked fine under 7.10. The one you can see at the left is the old 7.10 mesh. Trunk is showing, leavespart is showing. Now i have redone my tree with new MED from 7.50. Means reconverted it from FBX. And have imported that tree into my level too. And now the trunk part is not showing when running my level.
Have it. My mesh contains two textures. One with 24 Bit, one with 32 Bit. 7.50 MED turns my 24 Bit Bitmap into a 32 Bit one when i import the FBX file. And then the texture doesn't show anymore when i run the game.
I have manually changed the texture format back to 24 bit, and now my trunk shows. Phew
