Hello, I'm running Windows 7 64bit, and I have 2 AMD Radeon 6950's in crossfire. It has only been a couple of months since I used CS6's create 3D extrusion layer, and it used to work fine, but now it's greyed out no matter what type of layer I'm selected on. Photoshop is seeing my graphics card just fine http://i.imgur.com/LREws.png and even says that 3D is an enabled feature if I mouse-over the Graphics Processor Settings box. I have the latest 12.8 AMD drivers. So, something between Photoshop and my graphics card are no longer playing nice - maybe an AMD Catalyst software setting? Although I've made sure that all my settings were restored back to default. I should also note that all other GPU enhancement features that I'm aware of seem to be working fine (like the quick zoom rendering, etc.)
Why? Have you found Catalyst 12.8 to be faster somehow than the older version?
Hazunfefer is right, 12.4 was a particularly stable release to use with Photoshop.
That said, I haven't had it bad with 12.8... The one problem I *DID* have was that it didn't install as an upgrade to 12.4 properly. I had to remove it, then remove the OpenCL components in the Windows system32 and syswow64 subfolders, then reinstall 12.8 afresh. After that I have good results with 3D. But I only have one lowly video card (a 5670).
For me, they have some optimization tweaks for a specific game that I play. I'll have to see if my laptop's card can do the trick at all, I'd prefer to use that when the time comes that I need to do 3D than bother with changing drivers around constantly, even if my laptop isn't as powerful.
First step would be to keep 12.8 Catalyst, but you have to do a fresh install and clean the possible driver "left overs".
Download Driver Sweeper
1. Uninstall drivers + catalyst control center
2. Reboot in safemode, use DriverSweeper
4. Install Catalyst 12.8
if that doesnt work, use the same procedure but install Catalyst 12.4. Just to make clear it is the drivers causing the problem.
Ok, it turns out I really am just missing something in order to create a new 3D layer. The option is greyed out on any new PSDs I create, whether I'm selected on a text layer, smart object, or just rasterized graphic. I pulled up one of my old PSDs that had 3d layers in it, and they work just fine. Is there a step I could be missing? Thanks everyone
Ok, sorry to bother everyone with this. I apparently went full retard. An update must've caused photoshop to revert to default settings, and I was creating CMYK documents for some reason (which I almost never do in Photoshop). Worked fine once I realized that and made an RGB document. Uauhghhh *facepalm*
Glad you found the issue!
And thanks for that follow-up. Even though it seems embarrassing, don't be worried over it. We all zone out and do this sort of thing from time to time and your description of why it happened will no doubt help others who come across this thread.
I feel a bit silly as well, as I certainly know RGB is a requirement of 3D, and now you mention it I even remember going through this before with someone, so I should have thought of it.
Perhaps the best thing to do is to ask for / post a screen grab first, before delving into a problem. It would probably have jumped out at someone pretty quickly.
