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 🙂
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!
