Rendering from a spotlight view creates different perspective than viewport/scanline render.
Slight changes in spotlight falloff (say from 80 degrees to 90) makes VERY large changes in perspective in render.

We were able to repro this and fixed most of it today.
First of all, if the image aspect of the output is not 1.0 or the light is set to rectangular with aspect != 1.0, the PIXEL ASPECT is used to conform the rendering to the final output.
We have a bug logged against support of non-square pixels which is still not resolved, so Krakatoa’s output will not match the Scanline output until we fix that.
Second, the Field Of View of the Spotlight is being used in a special way when using Rectangular shape with aspect != 1 - the area of the light is kept constant by linking the height and width using the square root of the aspect ratio. We implemented our handling of spot and direct lights to match that behavior and the results incl. falloff and shadows now match scanline’s output.
The only thing we assume we will not support at this point is Overshoot which is completely ignored.
We hope to implement shadow density per light soon.
