Light Projection (Batsignal) with Cinema 4D
How do you mate a texture to “Stencil” a light in Cinema 4D? I am trying for the “Bat signal” effect. Most other 3D programs have mask/texture channels in their spots for this. Can it be done in Cinema 4D?

simply put a texture on your light, I use flat projection and the luminance channel of the texture. your texture can be anything from a bitmap to a shader or even a video clip. Use the texture tag and alignment tool to fit the projection.

You’ll want to use the transparency or alpha channel of the material for this. Turn on Visible Light>Volumetric in the light’s General tab.

if you find it a bit difficult to adjust the texture for your projection, try this little plugin:
