I have an HDRP project where I create reflection probes at runtime.
I tried to set them in Realtime/OnDemand and to call HDAdditionalReflectionData.RequestRenderNextUpdate().
And I tried to set them in “Custom” mode and to set their cubemap myself with HDAdditionalReflectionData.SetTexture().
But no matter what I do, even if the texture is good inside the probe, they don’t appear in the game. They only appear when I select them in the editor.
I upgraded Unity to 2020.1.0a23 and the HDRP package to 7.2.1 and it works now.
