I'm making a scene for mobile using the T4M plugin, and it only support 4 textures. I want to have more textures. So, I split the mesh. Then each mesh will have 4 textures to use. But, the side effect is the crossing area will have heavy ao effect... I want to erase this ao effect. I've heard that the lightmap can be modified by hand (maybe in photoshop with some plugin? ). Is it possible?
