This might be a silly question, since I don't know much about your setup: Is it just some of the normals that are flipped, or are they all flipped?

Houdini's normals are left-handed relative to the winding order, so they're the opposite of almost every other tool out there, unfortunately. If the mesh is composed of polygon primitives, you can try applying a Reverse SOP to it to reverse the winding order of all of the polygons.

Houdini Error Jan. 16, 2018, 2:57 p.m.

Hi MIDIManNI. I have the same recommendation for you as for BuddaZero above:

If you can provide a sequence of steps that reliably reproduce the crash, please submit a bug report at [] and attach the HIP file, and the text that appears in Help > About Houdini > Show Details. You can click the Save button to save the text in a file and attach that to the bug.

Hopefully we can figure out what's going wrong.

Change points / particle size? Jan. 15, 2018, 1:44 p.m.

Mantra uses the pscaleattribute for the radius of points; I think it defaults to 0.1 if there's no attribute present. It looks like if you put @pscale = 0.004;in an Attribute Wrangle, (or you can use Attribute Create, if you'd rather avoid VEX), that's a somewhat reasonable value. Hopefully you can play around with it and find some value you like.
