His grave well ! I practically finished a mini-game with 100% 2D models. ('Space Invader' clone)
I noticed that 'Remove' was not compatible with 2D models ... so I used 'Visible = 0' ....
Even if this is not optimized, the results are already not bad
E.g, I can shoot at minimum 2000 '2D Models' without an unpleasant slowdown.
So, now, will be very stable !
Thanks !
