We have a brand new look! Take a tour with us and explore the latest updates on Adobe Support Community.
I use Windows 10.
Ever since I updated to 22.4.1, my Render > Lighting Effects isn't working. There's no guide to move the light and I keep getting two baffling errors.
The first error insists that "Use Graphics Processor" should be checked... It is checked. I've even unchecked and rechecked it.
The second error insists I don't have enough RAM... I have 32 gigs of RAM.
When those two errors pop up it outright refuses to open the Lighting Effects workspace altogether but sometimes it WILL open it... only I won't be able to make any changes on the image. It'll show that there's some kind of spotlight out but there's no way to move it and the sliders do nothing to change it.
Repair attempts I've made:
1 - I've made sure that my video card driver is up to date. It is.
2 - I've selected View > Show > All to see if the UI was hidden. The controls still refuse to show up and the sliders still don't work. They move, but the light doesn't actually change.
3 - I've uninstalled and reinstalled Photoshop altogether. Still getting the errors and inability to manipulate the spotlight in any way.
I am a graphic designer that uses photoshop practically daily. I took a couple days for myself and when I came back it updated to 22.4.1 and now this is happening. Please help, I need to be able to use lighting effects for my job!

Try enabling this option in preferences and restarting Photoshop to see if it helps
Thank you, that seems to have done it!
You're welcome 🙂
So happy I found this! Was having the same problem and couldn't get it fixed. Finally!
Thank you also. I was having the same problem for a long time and this fixed it!
All this has done is grey out lighting effects. Any other suggestions would be welcome. I am using Mac with Big Sur 11.3.1 with an intel chip Macbook Pro 16" 6 core with 32gb Ram
This did the same for me--greyed out Lighting Effects!
Me too. Sigh.
I've given up testing to see if anything works!! Should be Adobe's job before they release a new version.
Summary: Reinstalled 3 times, checked that Deactivate Native Canvas flag - the filter works once then go back to re-edit same image or a new image, and the effect doesn't function properly. Tried resetting Preferences, still no luck. Enough is enough!! Previous version I guess 🙂
Did anone get the bottom of fixing this issue with Lighting effects?
I struggled with this, as well, having to install previous versions. However, with the 22.4.3 release by checking Deactivate Native Canvas in Preferences > Technology Previews and having the Graphics Processor turned on with Normal under the advanced setting with both options checked there, Lighting Effects is working again--at least for the time being!!
This solution fixed my problems... Thanks so much... Lighting Effects are one of my favorite in Photoshop CC...
Was your fix done on a Mac or Windows?
Mine was on Windows 10 if that helps?
Worked like a charm, Thanks!
I'm glad this worked for some, but all it did for me was enable me to see the lighting effects workspace (all I previously saw was either solid black or white with a few horizontal lines, revealing the image beneath). I have no way of manipulating the lights - there's no white boundary lines nor nodes for dragging. There's just the image. I can adjust the intensity of the lights on the side sliders, but nothing else. Completely useless. Brand new iMac, loads of RAM - same problem as my six year-old iMac.
Another Thankyou from me
Thank you so much. This worked for me.
I combined different suggestions from this forum and found a solution that worked for me:
1) [Edit > Preferences > Performance]
🗹 Use Graphics Processor
Click in Advanced Settings below:
🗹 Drawing Mode: Advanced
🗹 Use OpenCL
2) [Edit > Preferences > Technology Previews]
🗹 Deactivate Native Canvas
3) Close and restart Photoshop -- don't skip!
4) Make sure [Image > Mode] is 8 Bits/channel, otherwise Lighting Effects will be disabled.
5) Let's check the effects quickly with [Filter > Render > Lighting Effects]
6) Finally, I clicked on [View > Show > All] and disabled Grid and Slices.
7) Don't forget you can find the Reset button by holding Alt.
All these steps combined worked for me. I hope it helps! 🙂
Microsoft Windows 10 64bit
Adobe Photoshop 2021 22.4.3
NVIDIA GeForce GTX 970
Thanks for these detailed steps. On my Windows 10 machine I got the Lighting Effects to work simply by checking Deactivate Native Canvas.
The issue is with MAC OS.
Also, disabling Grid and Slices would take away functionality to make another function work -- that would be another Adobe flaw. 🙂
