Jittering shadow query
I have a blocky low-resolution shadow which jitters when the camera is moved.
Any ideas, anyone, how this can be fixed?

RE: Jittering shadow query
The higher the drawing distance, the lower res your shadows will be.

Also, make sure you are using a high enough shadow map size + count (D.shadowMapNum(6) D.shadowMapSize(1024-****))

Next, try fiddeling with: D.shadowReduceFlicker(true), D.shadowJitter(true) and D.shadowSoft(2)

Thx, Tottel
So it can only be fixed by means of code, and not whilst viewing in the World Editor?

Oh, it can be changed in the world editor too, I just didn't know that was important to you. smile

Press F12 in the world editor, change the same things in there.

EDIT: If you click on "Advanced", there is also an option to "Reduce Shadow Flickering". Make sure to read the description of it though.

RE: Jittering shadow query
Yes, much better now! Thanks.
'Shadowmap Size' was increased from 1024 to 2048
'Shadowmap Number' remained at 6
'Shadows Softing' remained at High
and, funnily enough, enabling 'Shadows Jittering' worked better that having it disabled.
The 'Advanced' 'Reduce Shadow Jittering' made no noticeable improvement.

I must remember F12... most of the stuff I've been doing until now has been via code and not via the World Editor, so I'm still a bit rusty about all the capabilities of the WE
