resizing and rotating static shapes do not break collision afaik
They work fine for player objects, but not for vehicles.
A scale of 1 allows vehicles to glitch through at high speeds, and tends to bounce the vehicle away when it does hit.
A scale of 0.2 tends to suck the vehicle in a bit, and allows vehicles to "push" their way through slowly.
Previous testing showed a scale of 0.5 to give perfect collision.
I ran into problems rotating a shape while making a loop de loop. The wheels of the Jeep were reversing direction and pulling me backwards around the loop when I got to the top bit.
Creating pre-rotated .dts files for each loop de loop section allowed the vehicle to react properly.
