I think that is what VPB is doing automatically for you, create PagedLOD
tiles. I started (again after years) with VPB just recently so give me some
time I might write you soon

Yes, there is no "high-level" way.  I hope it works for you.

Hi Alberto,

No. I was hoping to avoid hacking the CMakeFiles up. I will give this a try.

Thanks!

Re: [osg-users] [osgPlugins] Offline conversion to dds without gc

Hi,

have a look at NVidia Texture Tools (nvtt).

Hi,

Unfortunately our conversion-machine (virtual machine) has no 3D-graphics card, 
and therefore no graphics context.

Does anyone know a solution without the need of a graphics context?

Thank you!

Re: [osg-users] source data samples for VPB

[Nickolai Medvedev]

Hi, Nick!

If you create something like a game, i don't advise to use VPB.

I created own example. Now need to divide terrain into parts, then simplify, 
then write into LODs.

Here my test program:
