I am working in a dynamic lighting environment (all lights are moveable with raytracing, no baking with lightmass).
I have GI bounce light coming in through the windows into a room. There are curtains over the windows which I am treating as semi translucent (sheers). I am using an opaque shader with ss which has a nice look (translucent shading is not working very well in terms of a look).
When the sheers are over the windows, they are blocking most of the gi rays coming in. Is there a way to have the model not visible to gi. In other software packages there is usually an attribute/parameter to disabled this. for example in clarisse, “visible to global illumination”. Is there an equivalent in UE?
Cheers,
Jim
