One more rock…
In the same lo-fi scanning session as the last one (ie. a 20 minute window between heavy rain showers on the beach, no tripod, colour checker etc.) I shot this on my phone. Processed in Reality Capture, 3DSMax and Photoshop. I’m fairly pleased with how this turned out, again I was lucky with the lighting and all of the jpegs captured on my phone were aligned. There are some small areas at the base of the rock that are missing some detail due to automatic hole filling but nothing that couldn’t be cloned back in Photoshop. I baked out ambient occlusion and cavity maps to use as layer masks in de-lighting a little for PBR and then painted a roughness map based on some known values and colour selections from the albedo map. Once again, all of these shots are rendered in Toolbag 3 at 1440p and you can check out a real-time version in your browser below, be sure to go full screen and if you hold alt and drag the mouse around you can move the lights!
