The volume of a Region3 is capped, so if the region you’re attempting to make is larger than the capped volume; it won’t be any larger. I’ve encountered this issue before. What I did to bypass it was to basically split my Region3’s and make two different ones to fill up the same space; just divide the space between the two.
I see but if i create an other region, the space between the two regions not working so… i want to loop player in this Region but if i have a space the player won’t loop ^^
