WebJan 10, 2024 · As an example, sometimes I will get a uv with a u component that is 1.2. In order to handle this I am implementing a wrapping which causes tiling by doing the following: u -= floor (u) v -= floor (v) Doing this causes 1.2 to become 0.2 which is the desired result. It also handles negative cases, such as -0.4 becoming 0.6. acuzone cupping kit
