Lets make Lightmass EPIC (and understandable)

My 2 pc were used to build the scene. Main is core i7 4970k+16gbram+gtx980, second pc is core i7 2600k+8gb ram+gtx 760ti

I will take an old interior/exterior scene I’ve made that took 10 hours to build and try to see how I can reduce the time while achieve similar quality. stay tuned.
