Maya 2020 fundamentals - modelling the real world

Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

hi guys

have put the transparency issue to one side for the moment, as i'm trying to get an image onto the cd surface using the layered shader node

the diffraction effect works fine with just the one shader (pic 1), but when i add the picture - it comes in distorted around the polar axis (pic 2)

when i use planar mapping on the y axis, the photo looks fine, but i lose the radial effect on the diffraction!!!

anyone got any answers to this one?

cheers,
tony
(pix to follow)

here is a version with the 3 shader layers - photo, diffraction and transparency mask - still can't get the diffraction to look right the same time as the picture, though

Well, I tried it, and I got it to work user added image

Here is my Maya 4.5 scene file complete with my 512x512 test image user added image

Enjoy!

Basicly, I did what I talked about above, by creating a layered shader with a blinn containg the transparency on the bottom, and plopped the refraction shader on top of it.

The blinn also has the image in the color slot as a PROJECTION.

I had to adjust the projection for it to fit user added image

Here is my final render:

Can someone help me out here? Im trying to find the CD/Diffraction shader over at A|W, but I cant seem to find it. Can someone send it to me, or tell me how to get to it so I can download it?

No prob

A|W likes to plop stuff like that into a plug, rather than release he full code...

Now that I look at one of my CD's, I noticed something thats wrong with the one you made. user added image

The inner, clear part thats plastic, you have the rainbow effect on it. Take a real CD and hold it up to some kind of light. If you notice, that certian area dosent have that rainbow effect on it. Its just really shiny. Just thought Id let you know. user added image
