Hi there,
Sorry that the Oil Paint feature is grayed out in Photoshop.
Which version of Photoshop are you using and what is your computer's OS?
If Oil Paint is grayed out for you, try these steps:
Make sure Photoshop is up-to-date
Make sure that your document is RGB. Oil Paint won't work on color spaces other than RGB (e.g. CMYK, Lab, etc.)
If you're on Windows, make sure you're running a 64-bit OS with the 64-bit version of Photoshop. OpenCL requires 64-bit
Make sure Use Graphics Processor is checked under Preferences > Performance.
Make sure that your video card driver is up to date with the latest from the vendor website.
Note: If your video card does not support OpenCL v1.1 or higher, you may need to purchase an upgraded video card that supports OpenCL v1.1 or higher to gain access to the Oil Paint filter.
Information about your graphics card can be found in Photoshop's Help > System Info dialog.
For more information about using GPU features in Photoshop, including Oil Paint, see Graphics processor requirements.
Would you mind checking the steps mentioned above and let us know if that helps?
Thanks,
Akash
