I am trying out multi-materials and submeshes for the first time to accomplish applying multiple textures onto a mesh.
My mesh is a large diameter tube and I would like to tile a series of images on the inside of the tube.
This succeeds however my difficulty is in preserving the aspect ratio of the images.
How would I calculate my submeshes (I suppose this would be the indices parameters?) to ensure that the images fit inside the tube with the right aspect ratio? (There may be additional parameters on the texture itself?) I do know the pixel dimensions of my images.
