How best to create spotlights with various parametric light spread and falloff attributes in ArchiCAD, such that they work in octane plugin without further messing around? The average user needs to integrate visualization with documentation processes (the whole point of BIM) so light sources in visualization need to remain synchronized with electrical/lighting plans in ArchiCAD plan views - moving or switching from one kind of spotlight to another - with known bulb light output attributes, needs to be reflected in the visualization.
Also, how can interior still and animated renderings avoid graininess where there needs to be multiple material based light sources with specific characteristics (see above) rather than say a general area light from a single polygon. Currently, even with 16000 samples, the results I am getting look very grainy
Also, if coloured glass is in front of a light source (eg stained glass windows in front of the sun) how can I get the glass colours to be projected in vibrant coherent patterns on the far wall or floor as the light passes through the glass? And without introducing graininess to the rendered scene? At best I can get lead light patterns to project, but any glass colour seems to be washed out, (unless I make the glass nearly completely opaque - which them means transparency is wrong) - see screenshot
