Working with imageplanes

ZBrush Usage Questions
#1

I’ve been trying to figure out how to work with image planes, by following the tutorial on pixologics site (this one). The problem is I cannot assign the Flat Color material to my image plane at all, after I choose fill object and switch material it changes. But if I do this on the head model it works! Does zbrush hate planes?

Secondly I can’t find a way to reduce the transparancy of my head model in order to see the image plane underneath it. It’s done in the tutorial but with no explanation as of how.

All help greatly appreciated!

With the image plane selected in the SubTools list, select the Flat Color material. Turn on Draw>M and then press Color>Fill Object. This polypaints the model with the currently-selected material. (JUST the material, thanks to the M setting.)

Once polypainted like that, the SubTool will no longer change materials when you select a different one for working with the other model.

Thanks for the reply. That’s what I have been doing, but it’s not working. Filling the object on just the material channel works on other meshes, just not on my two planes imported from Maya…

Whenever I try to fill the the material on a image plane it does not work. Other objects it works fine, but planes will not keep the material. What is going on? How do people use reference image planes when they won’t accept a material. By the way I’m not trying to fill with flat color because I know that’s not a real meaterial.

Edit:

I just read that you weren’t using the flat colour, so perhaps this is irrelevent. Sorry!

Hello,

It’s to do with the flat colour material

"If you do not want the image plane to share the same material as your model please follow the steps below:


  1. In Tool: SubTool palette, select the X-plane subtool
  2. Select the desired material. See below if you wish to use the Flat Color Material.
  3. Select M in the Draw Palette.
  4. Press Fill Object in the Color Palette.
Note: you can assign the Flat Color material to a surface however, you have to do the following steps:


  • select the Flat Color material.
  • Press the Save button in the Material Palette and save it to disk
  • Select a Material that is not likely to be used like a Fast Shader.
  • Press the Load button in the Material Palette, and load in the Flat Color material.
This newly loaded Flat Color material will allow you to assign it to an object. When you are done, make sure to select your main mesh, and change back to your modeling material, such as Red Wax.

You might ask why? The Flat Color material resides in the 00 index of the Material palette. This allows it to be used to unassign a material to an object. Effectively, by assigning a material of 00 to an object it assigns no material to the object"

That’s from the chapter:
“Bringing The Image Plane Into ZBrush”

Found in the Online Docs here:

I keep a saved out version of the flat colour in the ZMaterials folder so I can grab it quick with Lightbox.

Hope that helps,

James
