I am having a lot of trouble developing material shader settings to create the look of clear cellophane in Poser 8.0.  Can anyone give me a hint as to how I might go about setting up the nodes in the material room to make a box prop look like a sheet of clear cellophane?  I can get by with really shiny glass if cellophane is not possible.

Thanks!

I don't have time to explain, but maybe somebody who has matmatic can make this for the OP:

View(Blend(Refract(1.01), Reflect(), .7 * TrueFresnel(1.45)))

or:

s = EmptySurface()

s.Transparency = .7 * TrueFresnel(1.45)

s.Alternate_Diffuse = Reflect()

No it isn't. :)

Edit: SAM, you are friggin fast, That message couldn't have been up a minute and you caught it. :oP lol

Coincidence, I assure you.  I was interested to see what people had come up with, since it's something I'd find a lot of use for, too.

Thanks for posting your setup, I'll definitely be using it in a render soon.  I have an idea for a Dalek covered in a transparent dust sheet, using dynamic cloth.  Your shader will be ideal for it, specially if I can figure out how to make it dusty in places.  Maybe SnarlyGribbly's snow machine can be tweaked for that.

how about blending in a texture with a transparency mask? Want me to fiddle around when I have a chance?

EGADS!  Cut a hole in that thing, the man is suffocating!!!

If you have the opportunity, that'd be great.  I may just try that myself; I ain't bad with textures and simple procedurals.  :)

One suggestion - lose Reflect_lite_mult.  Slows things down and does nothing for the appearance, IIRC.

Like shrink wrapping anythin with pointy parts, i.e. nose, fingers, toes, they poke thru if ya don't watch it. I was not paying attention with my heat gun and yes, those parts ARE poking thru the plastic. So fortunately for Michael, he can still breath... lol

Yeah, I forget about that sometimes... DOH!

Quote - OMG that was irritating... The image size exceeded the limit... oh well, nothing a lil compressing can't fix. So.... Here IS the material room :o)

Thanks for the image - also, your font is so funny! I'm surprised Poser can do this!

bill did a thread on this, a year or two ago IIRC.

Hey thanks much!  :)

And the screenshot:

... which is sort of pointless, I guess, really. The formula's easier and so is the mt5.

I made a mistake, Robyn. I meant to have an IOR close to 1 on the Refract. I forgot the first argument was color, not IOR.

Should have been:

View(Blend(Refract(0, 1.01), Reflect(), .7 * TrueFresnel(1.45)))

No worries: matmatic makes this really quick to fix! Thanks for the heads up - new mt5 attached.

ETA: btw, this was compiled in Matmatic 1.2.0, which has a few new goodies in it. Just in case you're wondering...

Wow, that's a lot of nodes from one little equation.

Sometimes, Poser's not very clever... has to do the best it can with what it's got. One of these days, SM will give us the UDN (user-defined node) where maths can all be done internally. Until then, we're stuck with the material room Legos.

A render with the antonia cornea shader modified

As you can see, 2 raytrace bounces are not enough .

Look again. I gave two shaders.

Apparently nobody tried that one.

i dont try cause i undertand nothing with matmatic ;)

Nope, not even me. Oh well, I did now. Sorry, Bagginsbill.

Ce n'est pas tres difficile, vous savez... enfin, si moi, une nulle en mathematique arrive a me debruiller...
