+1 same issue here (P3Dv5 HF2) using ActiveSky build 7479.

RESOLVED - Full P3D removal, registry clean (thanks Jorgen), and full install has resolved the issue. Unfortunately I do not know what addon caused the problem, however over the next month or two when I reinstall my products, I will check the PBR still remains. Thank you to everyone who posted with ...

I will be away working now - will report when I try it in a few weeks

Aussie1234 - what graphics card are you using?

Hi Rob,
No only upload was a Cessna addon aircraft. No scenery and no other addons added so far.

Further to this - the LM default F-16 textures don't display either.

I have now checked the permissions are all read/write for LM folder and in the Appdata folder. Still no PBR shows. Another update of the Nvidia driver 430.64 installed with no PBR. There are possibly more P3D users not realising their PBR is not rendering - I was one of them until installing a chrom...

Yes I have - no solution at this stage.

It's the beautiful Cessna 140 by Aeroplane Heaven. I was more familiar with it's younger brother the Cessna 150 in real life, so it's a product I am really interested in. I was totally underwhelmed by the PBR in the Maddog MD-80 with American Airlines livery (Thought it looked far too grey) - I now ...

When v4.5 first released we discovered that the content had to be updated as well as client to enable the bare metal look Hi Dan, I can confirm I have updated not only client and content but the complete sim - I am running only an 'out the box' version with one aircraft addon (which should show PBR...

Further to this previous post, I have deleted P3D and all addons, except the AH Cessna 140 PBR version. Unfortunately a new install of P3D (4.5.12.30293) has made no difference to what I'm seeing.

I am having issues where the PBR chrome shows as a dark grey (rubber like colour). P3D v4.5.12.30293 installed (full install), Nvidia GeForce RTX 2080 (latest driver). Windows 10 on my C: drive, P3D intsalled on D: drive. I have tried deleting/rebuilding shaders with no change. I am not aware on hav...

Further to this - the 'Delete Generated Files' and a new F-22 default set up appears to have cured the problem. I have also changed all the file permissions for P3D so I'm not sure what part fixed it (possibly all)!
Thanks Vaughan for setting me on the right path for a fix!

No I dont use KVPS and I'm using the Milviz P-38L that comes with P3D as default. Having removed the F-22 and returned it to Airplanes, the F-22 now does a CTD when selecting Fly Now! Looks like it's a permissions error!!! - one of the joys of getting a new PC.... Thanks Vaughan for the help - you h...
