Thank you Adamski,! All except for the XF-92A are DCS world 2.5. The XF-92A is P3Dv4. These are all repaints of mine. DCS uses PBR rendering. However, P3D is just about on the cusp of implementing PBR native. According to a recent interview with their project manager at LM it's going to happen before v5 is released and very soon whatever that means.
