My problem is my "player" when it is driving around acts like it's colliding with invisible objects. It randomly turns left or right or gets stuck driving over flat "ground." The ground itself also seems to be jittering or pulsing. I think gravity is affecting my level blocks and making them pulse. The crashes seem to happen when the level pulses. Also if I turn gravity higher the collisions get worse (-750). If I turn gravity low (-50), it seems to stop.

I have a level that was created with Blender and imported with MED. I put it in WED, and added a skybox. I didn't do much else. Did I miss a step to not have gravity affect the level, only the player?

I am using the trial version of gamestudio A7.

Read the manual, it is all explained there. But on a related note, the most obvious reason is that the ODE physics engine simply is bad. Which is why it will be replaced by PhsX in A8.

Ok, Thank You for the information. I guess I will leave physics as-is until I can get my hands on A8. I smoothed out the majority of the issue with ph_setcollisions, but random collisions with the ground still happen occassionaly.

I was talking more about ph_setautodisable, but alright...
