I decided that it would be nice to get some shots of IRL rock faces to gauge whether the digital rock map is suitable. This was to determine whether I'd be better off using a texture I've created in Photoshop, or an actual photograph for my shrine/ altar in my final CMP project.
I therefore traveled to Kirtlington quarry (disused), Oxfordshire to take some photographs.
These are a selection of the close-up shots.
The physical rock normal maps.
The virtual rock normal map - shrine/altar.
The virtual rock normal map - floor.
(Both virtual rock maps are half the resolution of those used on the model)
As you can see, the shrine/altar map is quite similar to the physical rock normal maps; however the floor map I thought looks too dissimilar. This is fortunate as my ritual ground will be all one texture - which I have now, through this test, decided is perfectly realistic being a virtual texture.
