Lets make Lightmass EPIC (and understandable)

I have a Dual-Xeon 2670 v3. 32gb RAM. My latest work, apartment, tooks about 20-25min to render. But the scene Riviera House tooks 5 hours. Maybe in this site PassMark Intel vs AMD CPU Benchmarks - High End you can compare your CPU speed with mine.

The parameter NumHemisphereSamplesScale it’s not enough to avoid lighting problems. You have to play with PhotonSearchRadius in some cases. You can speed up your rendering time with a good balance of these two parameters.

As I said, I’m going to publish a pratical guide for this process in the next few days.

Thanks, I’ve been over that list last night comparing performance and prices. Before actually taking a decision to buy that I would make a new topic and get more details on what would be best option for UE4’s lightmass. Does the number of cores have better impact then Ghz, would it be faster with 10 older CPU’s or 2 new ones etc. ( that kind of stuff). From what I know so far RAM has no impact on speed, you just need enough to load all that data.

But before that I want to see what comes out of this topic, conclusions on how to tackle lightmass in different environments, build time optimizations etc.

Muchos gracias for taking the time on the upcoming guide!
