Knowledgebase: KeyShot for ZBrush
Sending Models to KeyShot Without Materials/MatCaps
Posted by Matthew Yetter on 14 February 2017 02:40 PM

There are currently three methods by which you can send models from ZBrush to KeyShot without the material settings included.  This will let you export the color from PolyPaint or texture, but not have any effects from the ZBrush materials such as MatCaps.  

The techniques are listed here in order from easiest to most complex:

RGB Only (Basic Process)

  1. Load a PolyPainted model in ZBrush
  2. Set the Material to 'Flat Color' in ZBrush (The model should appear with only RGB coloring)
  3. Send the model from ZBrush to Keyshot using the bridge
  4. The model will now be displayed in Keyshot with only the RGB coloring


RGB Only:

  1. Send over the PolyPainted model from ZBrush to Keyshot using the bridge.
  2. After the model is sent right click on the model and choose 'Edit Material' this will display the Material area in Keyshot.
  3. Navigate to the 'Textures' Tab
  4. Change the Texture:  from 'Texture Map' to 'VColor'
  5. The model will now be displayed with Vertex Color (PolyPaint) only.
  6. You may need to adjust the Gamma slider in Keyshot to make the PolyPaint look correct.



RGB Texture Map Only:

  1. In ZBrush make sure the model has a Texture Map applied in the Texture Map area [Tool:Texture Map:TextureMap]
  2. Click 'Clone Txtr' to clone the texture to the Texture Palette. [Tool:Texture Map:Clone Txtr]
  3. Export out the texture map in anything but *.PSD (Keyshot will not load *.PSD files.) [Texture:Export]
  4. With the texture map still being applied to the model in ZBrush send over to Keyshot using the bridge.
  5. After the model is sent right click on the model and choose 'Edit Material' this will display the Material area in Keyshot.
  6. Navigate to the 'Textures' Tab
  7. Underneath the 'Mapping' area (arrow) change the 'Mapping Type' from 'MatCap +VCol' to 'UV Coordinates'
  8. Remove the *.EXR map that is current assigned to the model and link the texture map that you exported out of ZBrush.
  9. The mesh will now be displayed with its UV coordinates and the linked texture map only.
