Set this node to ACES 1.1, Input Transform: ACEScg, Output Transform ACEScct.

Now go to the Fusion tab and right at the end of your node tree, just before the MediaOut node, create an ACES Transform Node.

Select the clip with your grade, right click on it and then select “Generate 3D LUT (CUBE)”.

I’m assuming you have ACES active in the colour management tab and I’m going to assume you have ACEScct v1.1 and Rec.709 as your ODT, if your settings are different, just select different corresponding options on the steps below: Go to your Colour Page and select the clip with the grade you want to see inside Fusion. Also, bear in mind that your grade needs to be a general look grade with no local adjustments such as power windows or keys. Just bear in mind that as far as I know, Resolve’s colour management is not yet properly implemented in the Fusion inside Resolve so this is a workaround and it’s not perfect. If that’s what you want to do, there is a workaround to do that. Perhaps you mean a DaVinci grade as an LMT (Look Modification Transform)? I’m not really sure what you mean by using a Resolve grade as an RRT as you can’t or are not really supposed to change ACES RRT as far as I understand.
