PSSM Shadow Clipping Issue

[blitzcoder]

recently, I just had a second look on the Ogre 14 terrain sample and got this PSSM receiver clipping issue:

and on different angle

the issue is that we only consider the caster bbox for focusing the shadow camera:

we could also add the receiver bbox, but that would drastically decrease shadow resolution.

I would suggest adding fake casters to increase the bbox size for now

Here's another look below which is a more common angle for 1st or 3rd person cam.

comparing it to the same angle with Ogre 1.7 (2nd screenshot) and issue is not present.

Ogre 1.14

Ogre 1.7

mTerrainGlobals->setCastsDynamicShadows(true);

for 1.7 behaviour
