Post subject:  Problems with deferred pipeline
Hi again, just noticed that there is a few problems with deferred pipeline when using more than one light source. In Chicago sample when I'm adding another light to scene :
Code:
   // Add light source
   H3DNode light = h3dAddLightNode( H3DRootNode, "Light1", lightMatRes, "LIGHTING", "SHADOWMAP" );
   h3dSetNodeTransform( light, 0, 10, 0, -30, 0, 0, 1, 1, 1 );
   h3dSetNodeParamF( light, H3DLight::RadiusF, 0, 50 );
   h3dSetNodeParamF( light, H3DLight::FovF, 0, 90 );
   h3dSetNodeParamI( light, H3DLight::ShadowMapCountI, 4 );
   h3dSetNodeParamF( light, H3DLight::ShadowSplitLambdaF, 0, 0.9f );
   h3dSetNodeParamF( light, H3DLight::ShadowMapBiasF, 0, 0.001f );
   h3dSetNodeParamF( light, H3DLight::ColorF3, 0, 0.8f );
   h3dSetNodeParamF( light, H3DLight::ColorF3, 1, 0.2f );
   h3dSetNodeParamF( light, H3DLight::ColorF3, 2, 0.2f );

   H3DNode light2 = h3dAddLightNode( H3DRootNode, "Light2", lightMatRes, "LIGHTING", "SHADOWMAP" );
   h3dSetNodeTransform( light2, 0, 10, 0, -30, 180, 0, 1, 1, 1 );
   h3dSetNodeParamF( light2, H3DLight::RadiusF, 0, 50 );
   h3dSetNodeParamF( light2, H3DLight::FovF, 0, 90 );
   h3dSetNodeParamI( light2, H3DLight::ShadowMapCountI, 4 );
   h3dSetNodeParamF( light2, H3DLight::ShadowSplitLambdaF, 0, 0.9f );
   h3dSetNodeParamF( light2, H3DLight::ShadowMapBiasF, 0, 0.001f );
   h3dSetNodeParamF( light2, H3DLight::ColorF3, 0, 0.2f );
   h3dSetNodeParamF( light2, H3DLight::ColorF3, 1, 0.2f );
   h3dSetNodeParamF( light2, H3DLight::ColorF3, 2, 0.8f );
it looks like this with Forward pipeline enabled :

But when I'm enabling the Deferred pipeline, one of the light sources disappears :

and Chicago sample crashes after flying a few seconds around the scene.
test system : Windows 7 + ATI RadeonHD 4890 + 10.6 drivers + Horde3D Beta4 r251

Best Regards, Siavash.

Thanks for the hint. I will check that once I'm back from siggraph next week.

Well, I've tried this myself, with MinGW and an nVidia card, and here are my findings:
- also dissapears when the deferred pipeline is used
- the program crashes the moment the blue light (or where it should have been) goes out of sight -- so it works fine until it no longer has to render the blue light projected onto the floor (note that the program does NOT crash if the forward pipeline is used!)

I'll try to also look into it when I have time. The renderbuffer code has been changed a fair bit from beta4, and this also might explain why my color buffer shadowmaps are crashing my poor N900 phone in the ES branch...

The problem should be fixed now. Thanks again for the reports.
