I’m not the coder on the team but I believe we just play out our “mantle up” flipbook which has enough space to mimic the player climbing up the edge and we know the start and end points to blend back to the idle flipbook. The collision capsule actually stays at the lower mount point and just teleports to the final position at flipbook end frame, AFAIK.
If I have understood your question correctly, we haven’t disabled the tonemapper at all, we just made a few tweaks in the post process tonemapper to try and remove some of its aggressive contrast, such as tweaking the toe and slope values. We also made sure to disable the autoexposure completely in the project settings as the colours ramping up and down all the time in and out of lights doesn’t really work very well for a platformer. Hope this helps.
