Note: this article applies to Edy's Vehicle Physics (EVP) only. Refer to the other articles in the differential tag for articles related with the differential in Vehicle Physics Pro (VPP).
Modify the parameters in EVP's Vehicle Controller until you get the expected effect in each different setup (open diff, limited slip diff, locked diff). As a result, you would have three sets of parameters, one for each setup. You may apply each setup by modifying the parameters from a script depending on the diff setup active in the car.
For example, let's start with a perfectly balanced car that we assume uses a "limited slip differential". The values in the Vehicle Controller would be the base setup. Then we can create the open diff and locked diff setups for that car by modifying these values:
Open differential
- Less traction (decrease Max Force Forward)
- More slip in the drive wheels (increase Max Drive Slip and/or decrease Drive Force To Max Slip)
- Better handling in corners (increase Handling Bias)
Locked differential
- More traction (increase Max Force Forward)
- Less slip in the drive wheels (decrease Max Drive Slip and/or increase Drive Force To Max Slip)
- Tendency to understeer in corners (decrease Handling Bias)
