We import thousands of parts, and we recently noted that the default settings gave nuts and bolts more lightmap space then large panel parts, for example.
So far, we’ve only briefly tested the “Compute Lightmap Resolution” with the “ideal ratio” node, which did not make things better.
Ideally, we’d want to calculate the surface area of an imported part and assign a specific lightmap resolution from that, but I’m guessing that’s impossible.
Looking briefly at what we could find, there was a “filter by bounding volume” node, but we didn’t find a lightmap resolution node and we’re unsure how to actually use the filter node…
Our workaround right now is to use the Statistics window and set lightmap resolutions manually, which is incredibly tedious!
