Thanks for your reading. There are a question confused me, there are a femur model, and probe model. I control the probe to grind the femur. I can capture the collision caused by probe and femur. BUT I want to change the femur model outlook realtime. JUSH LIKE BELOW PICTURE
the white part is femur bone, and the green part is grinded region, if the probe model contacts the green part, the triangle cell will be change, the green part will disappear gradually.
how can i implement this effect?
