Made in blender, a single rock from rock collection 2 on my profile. This is variation b, which is slightly different from the other 5 rocks in the collection in a few ways. Note that this is just one rock. Check my profile for other rocks, or better will be if you buy the entire collection which is a third of the combined price.
Note that the vertex count above does not include the ground and is just for the rock.
You can also check my profile for a game ready version of this rock.
Layer 1 contains the rock. Layer 2 contains the lights. Layer 10 contains the ground.
Note that the rock texture is all procedural. You can bake it to the resolution which you want.
