Rob suggested the approach of creating a handful of modular pieces and baking very high poly textures down (Kyle showed me a quick and effective way of doing this in Z-brush using a mask which would be shared throughout all the pieces) we decided to give it a try and see if a modular approach would do the level justice.
Above Is the plan we came up with, each colour represents a segment that would then be repeated in its allotted slots. As it turns out we could make four distinct modular pieces and so we tried the method however it fell really short of the look we wanted and we abandoned it for the superior results that came from our baking segments cut out from the original mesh created by Kyle.
To get these results we exported a segment of the canyon that had added divisions into Z-brush where we would subdivide it until it was smooth. at this stage we applied the mask that all the rocks in the canyon would share and increase the deformation in each axis individually in the deformation tab to create a rocky surface. we then baked them down in X-normals and added the same texture to them all.
