Render lighting effects not working opens up darker in Photoshop

[lindaz59792994]

In the newest Photohop CC 2020, I can't seem to use Render lighting effects. In my old photoshop, I used spot quite often, but now (in 2020) I open it it is just dark. It does open to the lighting menu, but nothing changes on any of the settings or sliders except ambiance which only lightens the whole image. 

I thought this last upgrade might fix the issue, but apparently not.

Dave,

Thank you but it didn’t solve the problem. Now when I open the 8 bit image it either is still grayed out or when I first did it, it was showing the lighting area but there were no controls to select it , move it , resize etc. I could use the sliders to change the aspects of the filter but that is it. 

Very frustrating

This is excatly what I'm seeing as well.  Before making the suggested change, the option was available, but couldn't use it.  After making the change, it then becomes greyed out.

Hi Dave,

I'm running PS 22.4.3 on a win10 machine. Have checked deactivate canvas, use gpu is on, restarted PS. Still no control handles on the lighting effects (8 bit/RGB mode).

Now what??

Thanks

Mickey

For those of you who have followed davescm's advice for getting Light Effects and 3D to work and it DIDN'T WORK, here is some more information. I don't guarantee this will work, but it has for me (at least for the moment).

I just spent over an hour with an Adobe tech specialist. He accessed my computer. What he did was to go my user library directory: ~/library/preferences/ and changed the name of the folder called Adobe Photoshop 2021 Settings to something else (don't trash it in case you need to go back to it). We then quit Photoshop and restarted. On restart, Photoshop created a new settings folder.

When I reopened Photoshop all my preferences were reset. BUT the lighting effects and 3D were working on the latest version of Photoshop. Perhaps something in my settings was corrupted. Now, I don't know if it will last and as I'm changing preferences to make the app look like it did before, I'm only changing one pref at a time, restarting, and then seeing if the lighting and 3D are working.

My "Deactivate Native Canvas" is checked in the Technology Preview prefs. And, under performance, under Advance Settings, my drawing mode is set to Advanced. I don't know if this last one has anything to do with it. But the tech did look at it (it was set to that before). Also, my iMac is about 2.5 yrs old and I've got a AMD Radeon Pro 580 graphics processor, if that helps.

BTW, I nicely but strongly complained about Adobe's lack of response to our queries about this. Not just here but on their wishlist forum (someone had posted this problem on July 27 (not the first) and Adobe hadn't responded at all. That's bad customer service. And I told my tech that.

Again, I don't guarentee this will work for others. But it's something to try.

Sorry it didn’t work for me on my m1 mac mini running latest Big Sur. 3D did but I don't know if it didn’t before. Frustrating.

That's disappointing -- especially when I am on the verge of a Mac M1 purchase!!

I tried this Preferences reset. It worked once then back to square one. Are you still having success?

[Sri Gawn Tu Fahr]

so pathetic ... having purchased Adobe products for the past 20 years and now to be stuck with this problem ... Adobe could fix it if they set their mind to it but instead they ignore all of the complaints ...

[Ed5E57]

If you look at the information in the last PS update Adobe has announced they will be discontinuing all 3d filters and lighting. They have a small workaround which works now but will be gone soon,

Unless one of you has great blackmail .... Just kidding.   Its time to kill this string.

Still not working in todays version... 

[PECourtejoie · Accepted solution]

@maraziwazi , did you try to disable the native canvas in Preferences/Technology preview, as stated in the 3D announcement?

[belindas18877356]

yes thank you, that worked
