unstable grath

my displayed graph can not be stabled,some times apear,some times disapear,how can I solve it?

This could be any number of things. Could you provide more details about how you’re implementing it?

For some reason I’m thinking z-fighting or some kind of z issue. If you could provide some code (the more the better) then it will be MUCH easier to see what’s going on. :slight_smile:


Please do not double-post in both the beginners and advanced forums. Your questions definitely belong in the former.
