Render cast shadows in an alpha channel with 3ds Max.
that you will want to render the shadows…separately from the rest of the scene.…And in this case, I want to do that to…optimize render times for animation.…I've got a simple animation here of a flying saucer…flying over this desert mesa.…I can press Play Animation, and you can see…in the physical camera that we've got…We can visualize that by positioning the timeline…at about frame 130 or so,…and in the physical camera viewport,…we can switch the rendering mode over…from Standard to High Quality.…
And although it looks overexposed,…we can see that there is a shadow cast onto the ground.…I want to render that shadow out separately,…because if I were to render this out just as it is,…I would be rendering the same information 180 times.…So I can just render a still image of this background…and render a sequence of the shadow.…So let's take a look at what this looks like just now…without any special treatment.…With the timeline parked on frame 130,…I'll do a production rendering of the physical camera.…
