Hello everyone, what is the viewRange(...) function calling to change the shadow quality? It appears that as you increase the viewRange(...) the shadow becomes a much lower quality; I need to stop this from happening.

I have tried adjusting various shadow rendering options following a viewRange increase but it doesn't make a difference.

Has anyone got any suggestions?

You need to setup a custom shadow step function. Check the headers in the shadow section and you'll see it there.

No he's referring to Display.h where you can see in the Display struct the pointer to a custom shadow step function where it gives a brief comment about it.

It's implemented in the Esenthel RPG 2 code but I can't quite figure out what "the i-th out of 'num' shadow map splits" means. I'm trying to figure out a way to keep the shadow quality equal regardless of view distance.

I have some knowledge of graphics programming so this stuff but not a great deal so this is pretty new to me I'm afraid.

yes, 'num' will be usually equal to D.shadowMapNum
those are cascaded shadow maps:
