Using robs rough map , i have designed the final map of the main temple chamber, the centre areas will be fog/mist, this maybe changed to flooring depending on render experiments.

My final pillar designs for the main temple chamber, the two sketches on the left are to be placed free standing in the centre areas of the chamber, the right design will be adapted to form the main wall/ceiling supports featured around the chamber.

A detailed stone floor/texture design i created, could be used as a bump map for the texturing section of the film production.
