I just faced a problem working with After Effects on mac after installing Davinci Resolve. Everytime I activate the ray-traced 3D renderer and hit 3D in any of the layers, an error message shows up saying that there´s not enough memory for the renderer and that you should perform a CUDA update.
Now Resolve comes with NVidia CUDA drivers which´s UI can be found in the system preferences. It will be installed wether you have a compatible NVidia card or not.
Now, if you´re not able to use the ray-traced 3D renderer in AE anymore, the CUDA drivers are the reason for that.
To remove all the CUDA components, delete the following files and reboot after:
You may use the terminal to open the directories or hold alt while clicking on Go to at the finder´s top bar, which shows up the library there.
After rebooting the drivers are gone (check the system preferences). Worked fine for me!
Thanks for posting this! Recently installed a trial version of daVinci Resolve and couldn't figure out why Ray-traced 3D stopped working. This fix restored it.
