Increase the amount of total shadow cascades

So I was testing the new “Far Shadow cascades” in 4.8, and found some interesting behavior. The number of near shadow cascades and far shadow cascades can never add up to anything above 4, or the near shadows start to vanish completely.

(Ex: I can have 1 far shadow cascade and 3 near shadow cascades, or 2 far and 2 near, but not 2 far and 3 near)

Is there a way to increase the amount of total cascades I can use, or am I stuck balancing with the 4?

Console commands such as r.Shadow.CSM.MaxCascades=10 don’t seem to have any effect.

Hi Daniel -

That Console Variable must be set in the ConsoleVariables.ini file (usually found in …\4.8\Engine\Config) and even then it can be a bit misleading. The slider in the editor for Num Dynamic Shadow Cascades is locked by a UI element in Source to 4 as a Max number, but you can type in up to the max value you set in the INI file. You will also have to type in the number into the Far Shadow Cascade Count as well.

Thank You
