Hello Radiance community
I would like to ask you what is the best way to simulate external blinds in Radiance. I have tried both full ray-tracing and the mkillum approach but they do not yield the same illuminance values on the working plane. Especially close to the window (0.5-1m) large differences show up (100%).
What is the physically most accurate method? And if it is ray-tracing how do I obtain smooth results in a reasonable amount of time?
Best regards
