Mineways 10.15: Doubled billboards option

[Eric Haines]

Mineways 10.15 is out, with just a small change: Billboard objects can now be exported as single-polygon or doubled-polygon for OBJ (USD has sidedness built in as an attribute). By default, just a single polygon is output per face, "Double all billboard faces" is unchecked. Most digital content creation apps I tested are fine with single polygons for cutouts such as saplings, flowers, etc. However, Unity (for one; there may be others) needs two polygons output back-to-back in order to display properly, as it (evidently) performs backface culling on these. Checking the box will double these. This option is available for all file formats except USD, which has its own flag for sidedness. (Thanks to I C Y for this information.)
