4.14 LODs on Instanced Meshes don't use LOD0 Lightmaps
One for Tim Hobson, I suspect... :)
So we're having big problems with instanced meshes not utilising the lightmaps from the LOD0, which I believe is the expected behaviour. Consequently our project has rather hit a brick wall since lighting is one of our last big pushes, and our map is now a mess.
I wonder if this might be connected to the following ticket -- which I realise is foliage related, but then those are instances too... :)
Here's a screen shot comp of the lod1 popping in. We're using Instalod, but were also experiencing this with the in-built system too.
The problem you're running into, which you reference in the ticket above is a bad regression. The hierarchical instances in BPs are still affected by this as well. From a private note in the comments on the JIRA it's mentioned that it seems as though the lightmap is building properly and then becoming unassigned. Right now the target fix is for 4.16, but once a fix is submitted I will see if we can push to get this into 4.15 as well.
At the moment I don't have any workarounds other than using Instance Static Meshes over Hierarchical Instances since only the latter is affected.
