hi Rahul,
did you take care of the inverse effect of distance and pixel size?
An object far away (large distance) has a small pixel size on screen. So
you perhaps have to reorder your LOD range.

Hi Ralph,
Basically the object in my case is a terrain generated by using VPB. I
checked for the LOD ranges and they are Min : 1408.8Max : 1e+10 and Min
: 0 Max : 1408.8. Reordering them makes the terrain disappear.

While --sm, --sv, --pssm and --ssm don't (on my setup :

Which ATI card, which drivers?
I hear PSSM has troubles between ATI and nVidia cards, and doesn't work

Hello,
I've built OSG core and plug-in libraries statically. The performance I get is
quite a bit slower than using DLLs. It would seem that the performance should
be equal, if not better using the static libraries. I followed the instructions
from the link below.
Joakim,
I sent in a submission last year for loading complete cubemaps from DDS
files. That submission affects important parts of the osg core and
therefore Robert put it on the stack, which in practice means that it
won't be merged soon.

Hi Jason,
I think, you do not need multiple cameras. If you have

compute the average value.

Hi,
if you want to have it to be extendable to n-passes, then you have to go the
way you have proposed first. Create n camera's located on the same position.
