Re: Is Sunflow limited in Sweet Home 3D?
I get these messages with the "igi" global illumination

this.sunflow.parameter("gi.engine", "igi");
this.sunflow.parameter("gi.igi.samples", 64);
this.sunflow.parameter("gi.igi.sets", 1);
this.sunflow.parameter("gi.igi.c", 0.00003f);
this.sunflow.parameter("gi.igi.bias_samples", 0);

for SunSkyLight or ImageBasedLight only.
The consequence is a completely black image and a progress bar stuck in indeterminate mode.

So I changed the behavior of the progress bar.
It is also possible to disable virtual photons by choosing igi.samples=0. The higher this value, the greater the rendering time when there is no visual difference.
