Figure 1 - VUE Function Editor Workflow



Introduction

E-On Software's new VUE 5 function editor contains incredibly powerful features and capabilities to make or modify a virtually unlimited variety of materials. The key to understanding how to make your materials look and behave in a manner that you desire, is understanding how the new function editor works. This tutorial will walk through a basic workflow for using the function editor and illustrate several examples for combining and distributing colors and noises to create advanced materials. It assumes that the reader has at least a working familiarity with the function editor and VUE 5.

The Basics

Figure 1 illustrates the basic work flow for interacting with a the function editor. To enter the function editor, simply right click on the function preview window. In this case, a simple material comprised of a color map and a rectangular noise node is constructed. To add the noise node, right click and navigate to rectangular noise. Add a color map by right clicking and then connect the nodes as shown to the color output. To see the effect, left click on the real-time scene preview window to refresh the display.

One of the keys to understanding how various noise nodes affect a material is to use an easily understandable color map to see what values the noise is generating. A simple red-green-blue map can help to easily identify how a particular noise node function behaves. All noises generate values in the range of -1 (black) to +1 (white). In this particular case, the rectangular pattern outputs a pattern containing either a -1 (black) or +1 (white). This then maps to the color gradient map which ranges from -1 (red) to 0 (green)to +1 (blue) resulting in a checkerboard pattern of red and blue. Notice that there is no green or other shades of color in the resulting image because this particular noise does not generate intermediate grayscale values (e.g. +.2,-.2, 0, etc).

This Tutorial is lifted from another site. Not only that, but the 'beginner bits' are taken out for some bizzare reason! Here is the full tutorial, with a little more explanation at the beginning that should help! If your something to do with skinvue, then I apologise, but if your not this is simply stolen! http://www.skinvue.net/Tutorials/Vue5_FunctionEditor.pdf

A thousand "THANK YOU'S" and a few "nertzes" to those who criticized because the tutorial wasn't tailored exactly to their needs. How self-centered can you get!!!. AGAIN, THANK YOU for taking so much time to explain so much so clearly. All I can say is: I sure hope you teach, because the world could use your help. I didn't become an expert on the Function Editor in 10 minutes, either, but you sure opened my eyes and many "doors" that the e-on folks didn't bother to explain. I could go on, but I think you got the message (thank you, thank you, thank you! :-)

sorry about my not so nice comment... I was very frustrated that I couldnt get what i was trying to do. Id really like to learn more about the function editor. Right now I dont understand anything of it. Any help to get me started would be really appreciated...

I agree with Jeff. What use is a tutorial if it doesnt explain any basics for newcomers? Is it even possible to get the foamy shore effect in Esprit? I cant find the "distance to object below" anywhere...

I feel pretty stupid. I read through this tutorial and the function editor is just as mystifying as it was peviously. :(

thank you thank you thank you !!! For this much needed key into unlocking the function editor -- will make the information in the manual fall into place and become useful. As far as I know this is the only tutorial out there about the function editor in Vue 5. Bless you!

Wonderful tutorial. Really helpful for getting some use out of the function editor. Thanks for taking the time to write this and make the explanations so easy to understand.
