3D Compositing / ShadowCatcher / ShadowsOnly in CYCLES

Want to know how to composite 3D Objects over a Photograph/Video?
This Cycles Compositing nodes setup gives you a good amount of control over the 3D, shadow layer and backdrop of your scene.

Written description of what's happening:
This blender nodes setup used Render Layers to achieve a good amount of control over the 3D layer and shadows as they fall onto a photograph.

1) Moved the ground plane to layer 2 (M key). Moved camera and light to be on layers 1 AND 2 (M key, shift click on multiple layers).

2) Created new render layers, one for 3D layer (Monkeys), one for the Shadows (ShadowLayer) and the Ground Plane without the shadows (Plate). The trick here is to use the 'exclude' button for layer 1 for this to work well.

3) In the nodes setup, we have a different 'Render Layer' node per layer, plus a fourth 'Image' node for the background image.

4) The real trick here is the use of the Mix Node set to subtract. This will remove the shadow from the groundplane. The 'Invert' node then flips the alpha of that setup andshows only the shadows without the rest of the ground plane.

5) All layers are then sandwiched to create a final composite. Note that filtering each layer is fully allows (RGB Curves for example allows you to change curves of each layer individually). Blur or other options work well.

Bananas

After teaching a week 2 tutorial on modeling and texture wrapping a 3D banana...for the last five years, I think it's time for a change. Any suggestions on a shape that is easy to model and would be fun to texturize?

SuRender: USABLE MAP

Above is the usable map for the space. You should save this full size version (1024x768 pixels) and use as a background spatial reference image in Blender and/or After Effects. I repeat, USE THIS ABOVE MAP as the sole reference for building your scenes.

This may be more for a reference, but above is what the exact rectangle of projected light looks like hitting the space. Probably best not to use this as a map, but interesting to see.

And above is the color map projected onto the physical space. This may help you see what faces have been colored.

In case you aren't able to get the full scale images at 1024x768, here they are ZIPPED up:

Email me if you have questions.

SuRender: Test Projection Perspective View

Here is a test projection of colors mapped onto the most usable faces. Note that this photo is taken from the ground floor (DO NOT USE THIS IMAGE AS A MAP).

SuRender: Projection Mapping Specs

For the upcoming projection mapping show at the Cascades Fountain, it is important that we all follow these video specs:

Dimensions: 1024x768 (or if you need to scale down, 800x600 pixels)
Pixel Aspect Ratio: SQUARE
FrameRate: 24.0  (I suggest 24.0, but if you want to do 29.97 or 30.0, should be OK)

Video Codec: Quicktime H.264 or MPEG4, keyframe every frame, 'Limit Data Rate' to ~12,000 kb/s
 Please make sure that your final video is under 1.5GB.
