I've been experimenting with different aperture diffraction settings, and I'm having some issues...
When the aperture type is set to 'generated', everything works fine, and the scene exports.
When it is set to 'circular', everything works fine.
When set to 'circular', and an obstacle map is set, Blendigo crashes on export.
When set to 'image', it crashes when an image is set as well as when one is not.
Any help? I'm trying to create some interesting lens flares, but I'm not having any luck..

Here is the console error I get (on all crashes).
