This article lists all Corona error messages related to the DOF Highlights Solver (Max | C4D):
1. DOF Highlights Solver and AI denoising are enabled.
2. DOF Highlights Solver works best with "High Quality" image filter.
3. DOF Highlights Solver can only be used with non-VR perspective cameras without any distortion.
1. DOF Highlights Solver and AI denoising are enabled.
Full error message text:
DOF Highlights Solver and AI denoising are enabled. DOF Highlights Solver works best with "High Quality" image filter, while this filter may create artifacts with AI denoising. You can use "Tent" image filter (enabled automatically during IR in such case) yet this may be sub-optimal for DOF Highlights Solver.
This message appears under the following conditions:
- You are running production (non-interactive) rendering
- You are using AI denoising (Max | C4D)
- You have the DOF Highlights Solver (Max | C4D) enabled
- You have the High Quality image filter (Max | C4D) enabled (it is enabled by default)
In such scenario, the render settings are sub-optimal, because:
- DOF Highlights Solver works best with High Quality image filter
- AI denoising may create artifacts when used with High Quality image filter
The following actions are available in the error message dialog box:
- Learn more - redirects to this help page.
- Set image filter to "Tent" - Changes the image filter from High Quality to Tent. This is optimal for AI denoisers. The drawback is that such configuration is not optimal for the DOF Highlights Solver, however it should not cause any serious issues with the rendering, especially since the image is set to be denoised anyway.
- Set denoising to "Corona High Quality" - Changes the denoiser from AI to Corona High Quality. This way you can render with the DOF Highlights Solver enabled and still denoise your image.
Other solutions:
You can also manually adjust your render settings to avoid the combination of AI denoising, DOF Highlights Solver, and High Quality image filtering. For example:
- You can fully disable denoising and keep the DOF Highlights Solver enabled.
- You can disable the DOF Highlights Solver and keep denoising enabled.
The below table shows which feature combinations can be used without any issues, and which ones should be avoided:

2. DOF Highlights Solver works best with "High Quality" image filter.
Full error message text:
DOF Highlights Solver works best with "High Quality" image filter. Nevertheless, you can safely ignore this message and continue rendering with the current settings.
3. DOF Highlights Solver can only be used with non-VR perspective cameras without any distortion.
Full error message text:
The DOF Highlights Solver can only be used with non-VR perspective cameras without any distortion. The DOF Highlights Solver will be disabled.
This error message appears when using the DOF Highlights Solver and rendering from a Corona Camera ( Max | C4D ) with any of the VR or distortion effects enabled. In such cases, the rendering will start with the DOF Highlights Solver disabled.
