[osg-users] Mirror transformation

[Ale Maro]

Hi,

this is probably a trivial question but what is the most straithforward way to mirror a node?
I would like to use a MatrixTransformation so I simply set a negative scaling but the resulting node is totally black.
Is it the expected result or did I miss something?
I thought it was usefull to set GL_RESCALE_NORMAL mode but anything changed.
Any suggestion? 

My scene is built as follow:

Group->ClipNode->osgShadow::ShadowedScene->Group->MatrixTransformation->Group->MatrixTransformation (MIRROR)->osgFX::Outline->Geode

The last geode is visualized completely black. 
I exported the scene in osg format and opened with osgviewer and the geode is still black

Thank you. Best regards.
Ale
