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:)
Here is my Maya 4.5 scene file complete with my 512x512 test 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:) Here is my final render: http://www.ragecgi.com/public/SM/RAGEsmCD.jpg |

Just in case my hosting co does something to my sample image, here it is again on SM's server:

EDIT: Nice job on the CD, BTW. Looks awsome! |
Dam, you beat me to the post! hehe...
Yeah, after I posted that, I looked at my cd collection, and sure enough, I was wrong! hehe... I edited my post:) Thanks btw! |
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?

Ah, its a Plugin-In! I was looking under the shader area. Man, Im such a fool sometimes :D Thnx Izzy man!
|
No prob:)
A|W likes to plop stuff like that into a plug, rather than release he full code... oh well:) ...not too hard to figure out tho:) |
Now that I look at one of my CD's, I noticed something thats wrong with the one you made. :D 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. :D
|
Yeah, sorry, I was just lazy, and I wanted to just get it posted for everyone to find and fix:)
|
Ya huh, sure ya did. ;)
