Hello Ariasgore,

Did you also compile the 3rdParty dependencies from source? There is 
currently no package of precompiled dependencies for VS2008, and it 
could be that using the precompiled 3rdParty dependencies for VS2005 
with OSG compiled with VS2008 would cause this.

The plugins should be in a subfolder called osgPlugins-<version> under 
the directory where the OSG DLLs are found for your app. So if for 
example you are copying the OSG DLLs with your app, copy the 
osgPlugins-<version> folder along with it (don't change the directory

For another plugin like png for example, the plugin also needs the 
libpng DLLs to be found, which is often the problem when loading the png 
plugin fails. But for jpeg, that is not needed since the jpeg library is 
linked statically into the plugin.

So I suspect your problem is related to using VS2008 with 3rdParty 
dependencies compiled with VS2005. Note - I saw some reports that in 
release mode, it worked OK, but in debug it didn't. Regardless, it's 
much better to compile the dependencies properly to be sure you don't 
have problems with this in the future (plus, debugging is important!).

Good luck,
