This error message appears only when the following two features are used at the same time:
- "High Quality" image filter type in Render Setup > System > Frame Buffer > Image filter
- AI denoising (either the NVIDIA or the Intel AI denoiser) in Render Setup > Scene > General Settings > Denoising
Currently, these two features cannot be used together due to technical limitations. The pop-up message provides an option to disable the high-quality pixel filtering option (and keep the currently selected AI denoising active).
This means that to use high-quality filtering, AI denoising has to be disabled manually.
We would like to lift this limitation in the upcoming versions of Corona, so that using high-quality filtering and AI denoisers at the same time would be possible.
Note: The Corona High Quality denoiser can be used with high-quality filtering without any limitations!
