Sometimes a Blender model will produce webbing in Daz Studio. I have so far fixed such models by editing the geometry to remove the relevant concave n-gons.
But this escalator model seems un-fixable.
I think it has to do with that fact that the n-gons in question are made from curves and the object they are part of has multiple instances.
I tried converting the curves to meshes.
I tried editing the geometries as usual, in edit mode.
I tried exporting it to Daz and then re-importing it to blender (edit again) and exporting it to Daz again.
But no matter what I do, the webbing persists.
Is there a way to reduce the blender model to a pure mesh with no modifiers of any kind so that it will be truly editable such that I can remove the webbing?
