I think the topic title sums it up well enough.
(For anyone unsure, this is a completely separate option from the lightmass resolution settings, though it’s similar name makes them hard to separate.)
In static meshes you have the ‘Min Lightmap Resolution’ option under static mesh > build settings.
It’s pretty useful as a way to get a quick and dirty lightmap that’s more optimized for the resolution you’re going for. (Since it packs the uv shells to maximise texture space usage.)
However, it seems like it’s hardlocked to be 64x64px on every mesh that gets imported, but that wouldn’t be an issue, if not for the fact that I can’t really find any way to edit these in bulk.
Each time I want to update a mesh, I have to go to each individual mesh I want to adjust.
Then adjust it’s min lightmass resolution.
Then I have to wait for either a few seconds, or maybe up to a minute or two, while unreal is unresponsive.
Is there any way I could edit multiple of these at a time, so that I don’t have to keep doing 2-3 seconds of work, then have to wait for it to finish, then repeat?
Alternatively I should probably just pack these uvs in maya before import, but it’s way more practical to edit this in unreal based on needs.
