Custom Floor and Wall Textures
I apologize if this is in the wrong section, but I have not found a section specifically for Walls and Floors for Sims 3. This might be a stupid question and I might have my pasta eaten, but I have a question about specifically making a texture for a floor. I've seen joninmobile's uploads and I see that he has multiple parts on his floors that are able to be recolored. I was curious as to how this was possible and by what method this was possible. Were the floors made with Red-Green-Blue layers like a pattern would be (which I know how to make), or Red-Yellow-Magenta like CAS items? I ask if it's CAS because the clothes have channels that patterns can be placed on, and that is what I want to accomplish. I want to be able to make a specific floor that I can place multiple patterns on.
I know so far my posts have been questions, but I want to be sure of what I'm doing before I attempt to upload anything on this site. I'm still quite a beginner. I'm also sorry if this topic has already been discussed. I looked around all day trying to find the answer to my question.
Thanks in advance for the help. <3
