you won't know unless you try will you ? :-)

I have no clue - having recently learned about the nature of the resins currently being used - there's no way I'm getting a resin machine at the moment.
That stuff is nasty.
Eventually someone will develop a non-toxic low odour resin, then I'll think about it.

chitubox is the only resin slicer I know of.
There may be others, have a look.

It would seem logical that if the g3d software imports the chitubox exported stl - with supports, that it would also include those in the print.

My suggestion is to find something very small and intricate that uses a lot of support - but doesn't take long to print.
And run tests :-)

There is currently no substitution for a trial and error print test.

What I would do, is generate a bunch of small identical files with complex and supports - BUT vary the support settings for each model.
Then print several at the same time.
Given that each layer takes the same time no matter how large the model - it makes sense to do several test models at once.

Also have you tried the G3D facebook group ? (I'm assuming there is one)
The nerds - uh, experienced users - there will probably know how to fix your issue.
