  • Rendering plugin: [ogre ].
  • Running on a machine with no gpu (llvmpipe)

Description

• Expected behavior: INTEGRATION_gpu_rays_ogre_gl3plus should pass
• Actual behavior: the GpuRaysTest.Heightmap test case fails

Steps to reproduce

Just tested this with latest gz-rendering9 commit, 9e874c0, on Ubuntu Noble with no gpu, and I'm not able to reproduce the test failure any more. I don't think we've updated the OgreGpuRays implementation in ogre 1.x recently too.

Can someone else try run this test and see if it fails on their machine? If not, I think we can close this.
