Lights & Shadows

Overview:

Creating shadows in TouchDesigner takes a few extra steps when compared to setting-up a regular render network. Here much of our render set-up remains the same, with the exception of our Light COMP. For shadows to work correctly we need to enable them on the Shadows page of the Light COMP. The quality of our shadows often depend on having a sense of what our light can “see”. To help us visualize this we can use a Depth TOP and make sure the light’s Z-axis is pointing to the middle of the shadowing objects. Ensuring that the entire area where our shadow will be cast is within the view of the light will mean that we don’t have any unexpected clipped shadows in our render.
