[Max] General Discussion / Light diffusion material
« on: 2018-05-29, 14:25:42 »
Hello guys!
I'm currently developing a project where I need corona to simulate the light behavior of a slightly unconventional lighting system, and I'm doubting the results I'm getting in terms of it being physically correct.
The system itself will eventually have other layers of complexity, with LED lighting and sensors to mimic color and intensity of natural light, but for the purpose of this topic I'll go to the point.
I have a series of small/regular sized windows and, in front of them, I'll put some sort of light diffusion continuous plane to minimize the perception of the individual windows and create a more uniform strip of light.
In terms of direct visibility it will never be perfect using this diffusion plane only (hence the LED to improve the effect), but what I wasn't expecting was that the sun rays weren't diffused passing through it.
I'm using corona sun+sky (but I got the same results with HDRI) and I've played with all refraction, volumetric, sss and translucency values. The only thing that was constant was the defined shape of the windows projected on the ground. Shouldn't the light get diffused? is this normal behavior?
I made a quick real test with a laser and a polycarbonate panel and it did get quite diffused as I was expecting.
Am I missing something? Is it a known limitation?
Thanks in advance.
