Generating B&W Composition Thumbnails With Blender's Shadow Render Pass


Christina Myrvold writes:

Interested in using 3D as a quick way of generating B&W thumbnails? This week on POLYCOSM we show how the shadow render pass option in Blender can be super useful for finding good light compositions in your scenes, and how this render pass can be used as a way to generate thumbnails for for example client work, illustration work or even environment concept art.

Happy blending!

  1. Hello Christina!
    Could you tell me why I am not seeing Shadow for my render pass?

    I only have Combined, Ambient Occlusion, Normal, Mist and Subsurf..

    I love this technique, and I'm really looking forward to using it!

  2. Hi Christina!
    Just a note to let you know how much I appreciate your great attitude (I swear I can hear you smiling)! You are extremely talented and your perspective towards your art inspires me to see more of the simple in the complex. In this case something as basic as shadow transforms everything. I knew this before, but now I feel it! Thank you for that! :)
