I have latest toee mod + KoTB 1.1 + 1.11 patch but have two problems: The texture for the beginning wagon train are fine, but after going through the secret passage, the road and surrounding area leading into the keep seems to be textured with wrong textures or ones that seem very stretched. see bug playing tutorial thread for my other problem.
The detail in the chasm seems more distinct than the detail on the bridge. This sort of thing is likely on "home-made" maps. Co8 apparently doesn't have the resources available to the original developer. But they have ingenuity, talent and time.
Sorry, I have played a bit more and now that i am used to the gfx, it doesn't distract me from playing. I don't do python, but have been programming for over 30 years, so if there is any c++/directx I can do as a penance, i would happily contribute.
