The warnings are cause for concern since they may imply something not set up or modeled right. If they're overlap warnings, then they're usually modeling errors and those can affect export. You'll have polygons that coincide with other polygons such that the exporter can't consistently resolve a solid volume. What do a couple of the warnings look like?

Not at all, it should just work. The only issue I'm aware of is if there are interior "voids" in the data, i.e., holes due to zero-values in your data file, there may be an issue.

That would be very useful, maybe attached to a bug report so we can continue the investigation there.
p.s. Thanks for the f16 build warning report. That issue was already identified and fixed in our repo, so next source release will have it.
