This doesn’t seem like a known issue off the top of my head, but I usually don’t work with high poly test scenes, so I never noticed this personally.
Now that I think about it, we have noticed a drastic increase in export file size, and it would be good to pinpoint what may be contributing to this.
Do you know if the face count is consistent between max scene/babylon export? we may be duplicating vertices for each exported face, but this is just a hunch.
@nogalo if you can upload a test .max scene and .babylon that reproduces this issue, I’d be more than happy to take a deep look into it soon as I get the bandwidth, most likely within 2 weeks .
