This seems to be a pretty common question but I couldn't find a solution that works for me on a different forum. Many large textures on the ground are completely black and I'm not sure how to fix it.

I tried reinstalling the game, installing Better Rayman 3, changing the TnL to 0, and enabling Hardware Vertex Processing (this in particular made the issue worse by making everything appear as a silhouette). I admittedly did alter the TnL in a rather odd way, by copying the ubi file to the desktop and then putting it back into the Ubisoft folder, replacing the old file, so I'm not sure if that alteration worked correctly.

To be clear, my os is Windows 10, but I was also able to get Rayman 2 to work fine without alterations so I'm not sure if my os is the issue.

I should note that I'm not very knowledgeable about any of this, I only just got my own first computer, so being very specific in directions would be very helpful. But any attempt to help is appreciated...Thank you.
