I try to generate HLOD proxies by using “simplify mesh” option for hlod level 1 and it takes very long time.
So I tried the following: I took the mesh generated for the hlod 0, and used Merge Actors dialog on that. It is fast, and generates a nice lowpoly mesh without the inside parts as expected.
I thought something is wrong with my parameters, so I used exactly the same parameters and made sure that the cluster for hlod level 1 contains only the lod actor from level 0.
But it still takes ages, stuck at 5% forever.
Is there a way to execute it faster, like “Merge Actors” dialog does?
