[osg-users] EXTERNAL: Re: FBO setup not working..

[Rowley, Marlin R]

Robert,

Could you do me a favor and see if the example in the OpenSceneGraph 3 Cookbook, page 242 works on your computer?  I was originally wanting to test with that but when I get totally white on the left side of the screen (when it should have been showing the depth buffer), I went to trying the osgpackeddepthstencil.cpp file.

I just want to make sure I’m overlooking something simple.

Hi Marlin,

Hello,

I get the following error when running the example: osgpackeddepthstencil.cpp

RenderStage::runCameraSetUp(), FBO setup failed, FBO status= 0x8cdd

I have a AMD Radeon RX580.

I have just tested osgpackeddepthstencil on my Linux/NVidia system and it runs without errors.

Camera::attach() is the mechanism that the OSG uses to tell the OSG's rendering back-end how to set up FBO's, there isn't another route for this.  Perhaps it's an issue with the enum values used with the attach calls, perhaps GL_STENCIL_INDEX8_EXT isn't supported by your system.
With driver/hardware specific issues like this having feedback from a range of users is helpful as it can give us an idea on what OS/drivers/hardware hard problems, this then gives clues as to what direction to look into.
Robert.
