I can no longer render grids to photoshop in vanishing point. It's greyed out.

Hi

I've just tried here

Copied a background layer (Ctrl+J).

Used vanishing point and placed a grid

Rendered it to Photoshop where it is rendered onto that copied layer

Without being able to replicate it, the only things I can suggest is ensuring the GPU is up to date (which I believe on a Mac is deleiivered via OS update) and trying a preference reset.

Thanks. Here's a pic. 

I've just tried it in 23.5.1 with no issues, although I am using Windows 10.

Can you give some more details on your document size and show a screenshot of your layers  and options bar when trying this, so I can ensure I replicate exactly the same steps.
