Grayscale Elevation

ZBrush Artworks
#1

I have 3D Plane with hills on it. How do you convert it into 2D with grayscale elevation?

#2

See the AlphaCentury thread in the ‘Quicklinks’… :cool:

Here you go…I found the link! :slight_smile:

If you just mean to take the texture off your plane, I guess that would be a matter of using the MRGBZ Grabber tool, with your plane rotated toward you, grabbing both an Alpha and a texture.

I have been there and it is not what I am looking for.

It is opposite what I asked for.

3D Plane with hills to 2D Grayscale map

Sorry Dude…I got that and edited my post. :cool:

#5

I am still unfamiliar with ZBrush tools. Can you please post zScript if you dont mind :smiley:

I’m sort of involved in a project on this forum at the moment, but it is easy enough to follow I should think…
The tutorials that come with the software cover the interface, and how to use the tools. So in effect, I would be writing tutorials you already have… :wink:
Bur perhaps there is someone here with more time available who can oblige you…

Try this:

  • Assign 100% white color or blank white texturemap to your landscape.
  • Set the model so Z axis is facing you.
  • Turn all lights off and set ambient level to 100.
  • Expand render palette to access advanced render options and click on fog icon (upper left).
  • Set color palette to white and click on RENDER:Fog color 1 (turns white), set color palette to black and click on RENDER:Fog color 2 (turns black).
  • Click and drag on RENDER : Depth1 slider so the cursor touches the closest surface (mountain).
  • Click and drag on RENDER : Depth2 slider so the cursor touches the furtherest surface (valley).
  • Adjust RENDER:fog:Intensity slider to increase or decrease the gradation range.
  • Export image.

What you are doing is making the landscape white and self-illuminating. Then you’re looking through a fog which is a gradation from white (closest elevation) to black (furtherest elevation) encoding the Z dimensions of your landscape.

I think this is what you want?

I never thought of that, this could be useful, thank you.

This can be accomplished with the MRGBZ Grabber, Like Stonecutter says. It will grab depth informatiom.

Try this:
Alpha Mask

Just place your object like Svengali suggests, top down view, then grap it. You can then export your Alpha

This tut is inside the prog as “Alpha Mask” :slight_smile:

#11

I tried alpha mask tutorial. It popped a msg that I do not have AutoCrop.

BTW I am trying to get Gradient Depth Mask

#12

When you are following the tutotial, the buttons only show you where the tools and settings are. You will have to make the slections…

#13

Well, that’s a hell of a lot easier than what I suggested!

Sorry for the diversion there Wash.

That is what I did. When clicking on guide word “Tool:Modifiers:Auto Crop” It popped up error that interface item could not be found

then click and drag to select from canvas…

you get a texture and an alpha as a result.

#16

OK, let me just be sure…

Instruction A says Select the MRGBZ Grabber tool, and has a button to click on. When you click the button, an orange box shows you where the tool is, and highlights it.

This does not select it. You have to go to the tool menu and click on it there to select it. You get that message because the currently selected tool does not have an AutoCrop function.

You are doing this and still get that message?
