Hello Blenders
Again I have tried to work this but am going down rabbit holes watching unrelated videos.
So the panel between Suzzane and my light is blocking off that light.
How can I make that panel translucent so that it allows diffused light to travel through.
I'm trying to emulate real world diffusion panels, or scrims, which are placed in front of a light to soften and shape that light.
They come in different strengths or thicknesses, 0.5. 1, 1.5 and 2 stops etc. The thicker the panel the more diffused the light - which is used to make gradients across surfaces.
Thank you for any help.
My very best,
Jason
Hi Jason,
I'd use Cycles for this. For instance a setup like so:
I'm sure that you can get the effect you want in Eevee as well, but it would be a completely different approach.
Do not use a Translucent Shader for this, no matter which Render Engine, because it doesn't take the thickness of the 'diffuser' into account.
I think for that you're better of using IES lights, or plugging in a texture into your lights. JL did a short lesson about it here:

I've seen people using softbox textures that emulate the effect very well and not having to waste light bounces and calculations trying to emulate for real in the render engine.
