# How to make a mirror in Superfly?

• @bagginsbill A hah! [Inserts tongue in cheek and contemplates the sound of one hand clapping] a chance to correct the master!

I would have said for maximum realism, turn off your computer and go outside! ;-)

• Something like this works fine. Note I used the CyclesSurface and GlossyBsdf here for demo, not because it's needed. Any surface can do this.

• @bagginsbill

Just to be sure of the terms ...

Angle of incidence = the angle something is reflected at, right?

• Suppose you want Gold or Copper metal, not a silver-backed glass.

Well then you go like this:

Yes. The angle formed between the ray of light bouncing off the surface, and the surface normal.

• Colored metal that works both in SF and FF (because of special rules in SF -- this does NOT work in Cycles)

• Suppose you want Gold or Copper metal, not a silver-backed glass.

Well then you go like this:

Aha. I can sorta see what it does. I will have to putter around with this to understand it fully, but I get the gist.

Not that I'd ever been able to come up with this on my own, but I'm fairly good at studying nodes and figuring out which does what :) And then wreck it from there ;)

• @bagginsbill a question regarding the RayBias in the reflect node. Does that have any parallel in the GlossyBsdf or other Cycles sourced nodes, or is it completely internalised/irrelevant? And the Quality setting, as well. Worth playing with or just ignore in SuperFly?

I'm struggling because I really really abhor answering with "I think" vs "I know from experiments"

I have not tested this hypothesis but I think they do nothing at all in SF.

• Just the other day I was thinking that the shadow blur radius of an infinite light in SF should also alter its apparent size in reflections. I thought SM did NOT do this.

Turns out after I tested for it, that it did.
