Sorry i may have confused you.
I will add multiple devices via verse to get my desired outcome as a normal volume without custom mesh (Spline mesh in this case) work internally so with some code and tweaks itll work as it pick up the player who is internal to the volume edge.
What i should have made more clear so sorry for the confusion… Should i request via request forum section that the spline mesh should build the appropriate collisions ect when used with the custom mesh option on the volume device.
Thankyou again for the direction
