weird dots generated with tree support in CURA 3.2.1

[JF623 0]

Hello everyone! My first post here and I have a question about tree support in CURA 3.2.1.

 

After turning on the tree supports, some weird dots generates around layer 63 in the air. I tried unchecking the 'Show Helpers' box to make sure they are not coming from the model.

I have attached a few photos for reference. Anyone knows what is the problem here and how to fix it? Thanks!!

Is there a chance your model has some seam in it? Check the object for holes in 3D builder or something?

 

That won't fix the problem with the slicing, but it might make your print slice well enough to move on.

By seam do you mean holes on the surface / incomplete surfaces? I'll check the model again

Yes, poorly defined surfaces often trigger bizarre behavior when slicing. You can attach the STL here for others to check out, but bring it into a package that will check for and fix model errors (Win10 has 3D builder built in), see if it helps. Maybe try another orientation, too.

I'm having the same issue in Cura 4.
