I don't know about you but I never have enough rock references ! Here is a free pack of Wellington's beautiful coastline. Tried to "photogrammetrize" some of those rocks so you can see all the different angles I took of the same sections.
Photo resolution is 3000*2000, not as good as my other packs since I took these pictures few years ago with an old DSLR camera during my time at Weta. I figured could still make a cool freebie for texture and modelling reference !
Hope this help !
