How to get stable simulation when I need to climb steep hill with offroad car?

Question

I was trying to figure out how to get offroad Jeep to climb steep hill without sliding down the road. When I turn on "Check contact with body" under Driving control in order to get some additional friction for tires simulation goes wild. After couple of meters car just jumps into the sky and gets down after a while. I thought that there is some error in mine setup so I decided to download hummer example on your site. Unfortunately there was exactly the same problem. It seems that there is some kind of plugin bug in R20 release... Could you please help me with this? Thank you!

Answer 1

It's a very special issue, that cannot be answered here. Please contact our support team on c4dplugin.com.

Ok. Will do that. Thank you for getting back to me. Cheers.

I have just reviewed your project: The wheels don't spin, so it is a performance issue not grip. You have confused Power and Torque. The engine setup requires the max. newtonmeter value (Nm), not the horsepower (PS). I have set the max. Torque to 700 Nm and your car does the trick. Maybe you'll find better values to set the realistic torque curve. This is important for extreme drive manoevres.

Answer 2

The "Check contact with body" feature is not to get more friction on tires. It may cause, that the car stucks. I think, you don't want this feature in your animation, so I recommend to switch it off.

Simulations may get unstable, if parameters exeed physics. Please contact our support and send a reduced and zipped project file.

No, do not need this feature in my animation, but as wrote before, need to get that car up to very steep hill... could not figure out how to be honest. I will try to upload scene file... not sure what is the size limit though. Thank you.
