Hi (Art :) )
I just upgrade osgPPU to version 0.3. After I changed every osgPPU::Shader
to osgPPU::ShaderAttribute, my application still crashes in an unexpected
way.
But after a couple of hours of investigation (I almost went back to version
0.2), I finally found what was the bug. I have a lot of UnitInOut in my
application that add themself to create a specific effect.
Exemple :
osgPPU::UnitInOut * aUnit = new osgPPU::UnitInOut();
osgPPU::ShaderAttribute* aShaderAttribute = new osgPPU::ShaderAttribute();
aShaderAttribute->addShader(someShader);
aShaderAttribute->add("tex0", osg::Uniform::SAMPLER_2D);
aShaderAttribute->set("tex0", 0);
aShaderAttribute->add("tex1", osg::Uniform::SAMPLER_2D);
aShaderAttribute->set("tex1", 1);
aUnit->getOrCreateStateSet()->setAttributeAndModes(aShaderAttribute);
previousUnit->addChild( aUnit );
aUnit->addChild( aUnit ); // this
line seems to not be valid anymore
It seems like this is not a good practice anymore and I didn't find a way to
replicate it.
Hope you can help me
Thanks
Alex
