the documentation says that packed level instance is “optimized for rendering”, and i’ve read somewhere that at build time unreal is automatically batchign static meshes to instances as much as possible.
if that is all true, is it worth the both to manually batch repeated static mesh actors to instances if they are already in a packed level instance?
Looks like the answer is yes. if you open the blueprint created for the packed level instance, static meshes are converted to ISM’s when possible.
One problem this creates is that if you setup some logic to use on the ISM’s, like maybe changing materials, this will cause an editor crash any time you select the ISM’s in future if you changed the static meshes at all. seems like the reference gets broken and doesn’t know how to resolve.
