Rock - Photogrammetry based Environment Texture
Another rocky surface I captured recently. That one had surprise :) I didn't expect ..
I thought when I was shooting these things in cracks that these are small rocks .. apparently they are not. Have found them analyzing images when I was back home. It is still not bad as it is hard to notice on that texture .. but you should see the next texture I captured :) .. omg!!!
That scan was processed just from 4 images :). They were taken from pretty long distance as that surface is located high and was hard to cover from close distance. Not mentioning the closer I was the more crunching pebbles I had under my feet ;)
Surface itself was quite easy to scan and fun to process.
My current workflow I follow
As it was very windy I used my backpack to stabilize camera. I shoot from distance as that surface was located quite high. Camera setting: 70mm focal length and f/8.
To capture that grass I took just 4 images and it was enough to generate 6mln poly mesh
Additional details I wasn't aware of :). Just check cracks and holes
Zbrush - lowpoly model positioning over 6mln highpoly mesh used to bake normal, albedo, bent normal and ambient occlusion
Substance Painter - puzzle solving with 'Crop Tool' .. that one was piece of cake. Took just about 2-5 mins to have it done as I had to remove grass too.
Substance Designer - processing final PBR textures
