The amount of proceduralMesh is limited by 240

I use proceduralMesh to create dynamic wall in my scene.However when i create the wall more than 240,an error has occurred:
All objs in scene become larger and larger,than filled the whole screen。I think there is something bug occurred when the obj is calculating the projection matrix。
how can i use more than 240 proceduralMesh ???

Hello! Can you add some screenshots and share some more info? For example, what is 240 - num of actors, or scale of actor, or num of vertices?

i have combine all the meshs together to slove this problem,but i don’t know how this problem come。maybe this is a bug

240 number of proceduralMesh
