I am making a sort of spiderweb material, and when I turn on raytrace refractive mode, it gets nice and glowy and looks perfect, but it takes about 15 times longer to render…Is there any way to achieve this kind of effect through some other way using blend materials or something? What exactly is it doing when you turn on refractive mode?
It creates a volume fog inside the object which is then raytraced. What are your AA settings by the way? You might be able to improve render times a bit by playing with the “subdivs” parameter for the raytraced single scatter effect.
Best regards,

Thanks for the fast response…I lowered the single scatter subdivs from 8 to 3 and it is much much faster now…although I don’t know how flickery it made it for animation purposes. My AA is adaptive DMC 1,3 with a threshold of .01
Well nevermind…it’s just way too slow to render. Is there any way to create a bright white semi-transparent material that reacts to shadow (similar to the fog that gets applied) that I can use in a blend material instead?
Can you post an image of what you want to get?
Best regards,

have you tried glossy refraction?
