Hi Guys,
I am developing this interactive where I have two meshes. Overall I am quite satisfied but it occurs that sometimes (can’t say differently) when I pick the object with the mouse and rotate it, it starts flickering… and I can’t really figure it out why. can you please watch the video and may be you can have a better understanding on what’s happening.
Many Thansk for the Help!
