Since a few weeks (I don't know exactly when), the HDR effect in iClone 5 no longer works, both in the 32-bit and 64-bit versions.
As I had just updated my NVidia display driver, I reverted to the previous version, but that did not fix it, so I went back to the latest driver.
I then uninstalled iClone 5, rebooted, and reinstalled using the full version of IC5. That did not fix it either.
I don't know exactly what else I could try. I know IC6 is around the corner, and hopefully it will import IC5 projects just fine, after which this is a moot point. But it is still weird...:crazy:
EDIT: This has been solved---HDR was switched off in Preference settings.
