The game engine does not have full support for the subdivision modifier. I suspect that the amount that it does work is mostly by accident. Your best bet is to apply the sub-div modifier.
okay then…
thx for the answer
@dani8190 Hi, I stumbled upon this post in my quest to apply a subdivision during runtime (game engine) and it looks like you did it. My question is… how? Thnx in advance
Did you add a material on it?
I had the same thing last night, i solved it for myself by adding an material to it.
Maybe it works for you aswell.
