Hi there. So this is frustrating.
We have an environment / landscape that consists of 120 or so different meshes. We have this heavily divided as to aid in culling. We are now applying additional optimisation in the form of a secondary LOD group for screen-space distance triggers. Problem is as soon as we place our 120 highpoly sections in LOD0 and our lowpoly sections in LOD1 under either Maya or 3DS. When we export everything is fine and reimports separated om sections as one would expect, however, when we import under UE4 the sections in each corresponding LOD group are merged into one single mesh, defeating any culling.
We have disabled ‘combine meshes’ when importing in UE4. This works fine if the sections don’t reside in the LOD groups, however it merges when they do. We really don’t want to have to break up and import every section manually. Have attached our mesh as to help with any debugging. This is not our final model, simply a test, so do leave the critique subtitle.
