Title: self shadowing resolution bug
Post by: Vinkman on August 27, 2018, 04:14:57 PM

HiTech,
As promised here is the best I could do to show the issue I described in a previous thread.

The above Three phots show the cockpit shadow on the Wing of a 109. As the plan rolls right the shadow moves further out on the wing. As it does  the image goes from very sharp on the inboard part of the wing (pic#1) to a point where it transitions to blurry at the wing mid point. Pic#2 it is half Blurry on the outboard part and half sharp on the inboard part. Pic#3 it is all blurry on the outboard part of the wing.

I'll take a look if I can better optimize the cascading shadow splitting planes. How it works are 4 shadows are drawn, Each is used for a different distance. I.E. 0-x feet shadow 1, x to y feet shadow 2. Your simply seeing the first split.

I knew you were working on this some time ago. I remember that in the older versions, and on my old rig, the self shadowing was a big FR hit. I think the new routine is better  but my new rig is so good, I think it could run higher resolution through all the splitting planes.

Currently running max sliders, all options on, at 4096 res and running v-synch pegged at 60 FPS. so I think I have some head room.  :salute
