This document will cover how to set up NVidia FLeX for Killing Floor 2.
It should be noted that using this system and indeed setting it up REQUIRES that you using a FLeX compliant card. For Killing Floor 2 it is recommended that you have a NVIDIA 970/980 GTX to get maximum results but the 770ti will run it on low.

Using the above asset as an example, the asset has a low triangle count. On the right side there is Flex Collision drop down. The options are Auto, On and Off. When the default option of Auto is set, the drivers/engine will attempt to find the best fit for the flex collision based on if the poly count is low or if it has a collision primitive already. If it has a collision primitive, FLeX will use it as it's collision model. If it does not, however, then it will try to use "per poly" collision. If you set an asset to have Flex Collision ON it will implicitly attempt to use per poly collision. If you have Flex Collision OFF it will ignore the asset altogether.
If you are using the public SDK (Editor) you will not want to change any of the settings in the brewed packages that TWI ships with the game. I added this information for assets that are newly generated in the public SDK.
