everything in the negative light direction will not be lit by a directional light.
see attached maya 2013 scene.

This is a known issue in Krakatoa. Krakatoa currently uses the light position as the “origin” of the directional light, and Maya lights do not. I plan on fixing this.
There is another known issue with directional lights: Directional lights in Maya have infinite “radius” (like the sun). However, Krakatoa lights must have a finite radius (the smaller the better). In Krakatoa, the directional light’s radius is defined by the shadow map’s “Width Focus”, and the resolution of the light is defined by the shadow map’s “Resolution”. This is the case even if shadow maps are turned off. We don’t plan on changing ours to infinite radius because it would have other negative consequences, but we can possibly make the controls easier to use, as they are kind of unintuitive right now.
However, for your actual bug report (negative light direction), we can fix it, and plan to.
one more input for krakatoa attributes on maya objects (just like the light radius). renderers in maya usually tend to have a special dropdown in some objects (for example lights) that will show renderer specific settings. mentalray ray has that, arnold has that and with vray you can add custom vray attributes when needed.
using existing attributes might be strange for the user as they might actually be used by another renderer in the same scene doing something else than in krakatoa.
so just a thought…
Ah, yes. This is a good idea. I think I’ll add extra attributes to handle it. Thank you for the suggestion!
