Here's a general sample that will make an arc of a Shape meter (red color) behave exactly like a Roundline meter (blue color) - no transformation matrix needed:ÞeSheepMan wrote: ↑July 15th, 2024, 9:03 pm This was what I was looking for, but is there anyway to start it at an angle, one the same as what 0 speed on a speedometer would be? An angle at the lower left?
