Hi,
I asume you built 2 different databases and tried to display both of them.
You have to build all your data in single database and only load that database.
Search also in the mailing list for optional layer to learn more about
advanced database setup.

I have an osg:Camera (beyond the viewer's default camera) and I need to resize

So I thought to handle the viewer's RESIZE event by calling the setViewport(.)
method on my custom camera
Hi,
I know that I have to load one database but I think that I have to build at

But I've already had hires chunks and want simply insert into globe.
Is it possible to patch one .osgb with another .osgb in vpb?
Hi, Sebastian
I think you can create stateset on top of your shadow casting graph, and set
all state you need to enable and disable explicilty with override flag, like
disable textures, blend, color write, texenv stuff, lighting etc with
appropriate attributes\modes. Also you can copy graph
Hi Adun,
no, you can only patch with source imagery, not with a VPB database as far as I
know.
Your suggested approach seems to be:
1. Build globe from sources
2. build hi-res insets from sources
3. Patch globe with results from 2.
My recommendation is:
1. Build globe from source
2. Patch

Hi Sergey,
Thanks so far for the hints. I was thinking something similar.
The problem however is how tell the shadow-technique that one graph is
for casting while the other is for receiving. Do I have to overwrite
certain parts of the ShadowedScene class to achive this?

So if this is primarily for mobile devices, would that be useful info to add

You should be able to manage this with cull masks on cameras (cullmask on
camera that render shadowmap to render shadow graph, cullmask for main camera
to render main graph ), like use 0x1 on shadow graph and camera, 0x2 on main
graph and camera.

Hi,
ah!
vpbmaster calls osgdem to perform all the single processing tasks.
osgdem failed, therefor vpbmaster blacklistes the according host which is
unfortunately in your case your OS. Now vpbmaster has no machine available and
stops to process pending tasks.
look in the according *.task file

Maybe you try to reproduce this error that happens only if you try to build

You might have 16 texture units but only 8 texture coords. And fixed

You were right I was using

I have reverted to a simple glGetIntegerv(GL_MAX_TEXTURE_UNITS)
