Shader Parameters

Is there an easy way to compare a list of shader parameters on one part of a figure with another to find out what is different?

I was rendering a figure yesterday and I noticed his hand looked like they were in shadows. But it wasn't a natural shadow. The shadow covered all the hands and fingers but ended sharply at the hips. It was a transparent "shadow" because I could still see the detail on the skin.

All I did was load the figure with his texture and then I selected the figure on everything in the shader panel that applied to him and then applied the !IrayUberSurface, so I don't understand why the hands aren't the same as the figure. But I figure that something must be different between the hands and the rest of the body.

So I was wondering if anyone has a better way of comparing two shaders. I have gone and written down all the parameters and then gone through and tried compairing them. But even that is all that easy because the list from one part to another is "sorted" differently.

    This might be pointing out that the two skin surfaces don't actually have the same shader applied; they ought to be all in the same order. Look at the Surfaces tab and make sure the top of the tab indicates "Shader: Iray Uber" for all the skin surfaces.

    How exactly did you apply the Iray Uber shader? It's possible to set things up so that only some of the figure surfaces are selected, and not notice.

    While still painful, taking a screenshots will at least allow you to view the two sets of parameter side-by-side without having to write anything down.  You will have to do several screenshots after scrolling down, and crop them of course.

    Thanks SpottedKitty and sriesch.

    Somehow the shaders got messed up a little. I ended up fixing it by reloading the base texture. Probably could have fixed it by going through the settings.

    Thanks a good idea about doing the screen capture of the parameters. Sure beats the heck out of writing them down. What a tedious experience that is.
