Creating Chromadepth Image From Maya
This is a text supplement to a video you can find here:
1) Turn on Maya Render Layers – This is ONLY done one time. Once this is done your Maya will stay this way.
- Windows > Settings/Preferences > Preferences
- Rendering – Preferred Render Setup System – Legacy Render Layers
- Restart Maya (Again you only need to do this once).
2) Load your file!
3) Make sure your file is lit properly. Lighting is needed for the composited image.
3) Adjust the zoom and rotation of your camera until you are happy.
4) In your render settings, set the resolution to something high (such as 3000×3000) also make sure that Alpha Channel (mask) is checked!
5) Render your camera. Make sure the image looks good. This is the base image you will be colorizing later so repeat until you are happy.
6) Save the image as a PNG file. We need to use PNG so that the non-image area is transparent and not black (even though it looks black on the screen).
7) Go back to the render settings and set to something low (such as 600×600) this makes the next steps go faster.
8) Choose the Channel Box / Layer Editor Tab on the right side of the screen.
9) Choose the Render Tab (Which you have because of step 1) (At the bottom on the right)
10) Select all of your objects. Select > All
11) Create New Layer from Selected Objects (this is the last icon when the Render Tab is selected)
12) Rename it something nice that you will remember.
13) Right click the new layer and select Attributes
14) In the Attributes Panel, click the Tab of the layer you just made.
15) Click the Presets button and choose Luminance Depth
16) Look for the slider marked Out Color. Click the little arrow button thingy at the far right end of it.
17) Right click on the Old Min and choose Break Connection
18) Right click on the Old Max and choose Break Connection
19) Render to see what you have. Keep the Render window open.
20) Adjust the Old Max number until you the image starts to get clipped (in the far) with black.
21) Repeat until there is no black in the rendered part of the image.
22) Adjust the Old Min number until you the image starts to get clipped (in the near) with white.
23) Repeat until there is only a touch of pure white in the rendered part of the image.
24) Set the resolution back to 3000×3000
25) Render the image
26) Save the new image as a PNG
27) You now have the original rendered image and the z-map image, both as PNG files.
28) Leave Maya
29) Download Palette file from here.
30) Launch Photoshop.
31) For the nuances of what happens next.. watch the video!
32) Open the Z Map file.
33) Image > Adjustments > Levels – Frame the data with the Black and White Point without clipping any data.
34) Create a new layer
35) Fill new layer with black
36) Move layer under the Z-map layer
37) Layer > Flatten Image
38) Image > Mode > Grayscale
39) Image > Mode > Indexed Color
40) Image > Mode > Color Table
41) You should now see a grayscale color table. Click Load… and load the Chromadepth palette you saved in step 29.
42) Image > Mode > RGB Color
43) Leave this image there for a minute.
44) Load the rendered file in a new tab.
45) Image > Adjustments > Desaturate (to get rid of any color)
46) Image > Adjustments > Levels (adjust as needed for a good contrast)
47) Select > All
48) Edit > Copy
49) Return to Z-map Image
50) Edit > Paste Special > Paste in Place
51) In the Layers menu. Set the Layer Blend to Multiple
52) Layer > Flatten Image
53) View, Save, and Enjoy!
Note> After step 33 you can go back into layers to distribute the graypoint to choose if the image has more warm or cool colors.
