[osg-users] osgvolume: Swap technique in a VolumeScene fails

[Julien Valentin]

Hi,

First, excuse the lack of details of the further, i haven't been able to debug enough to understand where the bug is...

So, I tried a simple scenario with the osgvolume::MultipassTechnique:
I initialize the volume rendering with MultipassTechnique (as in the example)
And at runtime I change it to a new osgvolume::MultipassTechnique
It yields a weird crash in  MultipassTechnique::computeRenderingMode() 
with _volumetile==NULL ...?!

So far I've debugged a lot but haven't been able to locate where that happen
Any info would been welcome

Thank you in advance
Have a good day!

Cheers,
Julien
