Hey Everyone,
I was trying to follow Lee Griggs' Tutorial "Refractive Portraits"...However, I'm having a problem with the graph nodes...I don't understand with attribute/parameter he uses to connect te "RenderCam" node to the projection node.

Thank you in advance!
That is automatically done in Maya when you project a file texture. That is an Arnold 4 tutorial btw. It may not work properly with Arnold 5, in case that is what you are using.
It is automatically done when i create which node exactly?
Because what I do is go to the alshader for example on the diffuse color...and instead of clicking "file" with the left mouse button I use the right mouse button "create as projection"...and the render node is created when I create the camera , but it doesnt connect to the node...so I dont get what I'm doing wrong
We don't support alsurface shaders now I am afraid. If you use Standard Surface in Arnold 5 I can help you.
You need to change the projection type to 'perspective' and then choose the Rendercam underneath.
Oh, Okay let's say I use a standard surface in Arnold 5...How do I know which attributes correspond to the alshader?
Test Transmission, IOR etc. Experiment and play around to see what works. Let me know if you come up with something that works.
Hey, I downloaded Maya 2017 since it contains arnold 4 and installed the alshaders...And then I did the tutorial from start to end. However, It doesn't really seem to work, this is how it looks at the moment when I render:help.png
and this is my hypershade:help02.png

Sorry, I can't help you with alsurface or Arnold 4. Did you try it with Standard Surface in Arnold 5?
@Lee Griggs No, I guess it's possible to do it...but I don't know which values to use for the attributes and to which attributes connect the projection shader, as I guess the name of the attributes will be different being a different shader.
It may be difficult to reproduce, but worth a try. Try experimenting with adding the texture to IOR, Transmission and just see what happens. That is how I came up with it in the first place, by just experimenting.
