Using Python To Quickly Add A Real Time Shadow To Your MotionBuilder Scene.<\/figcaption><\/figure>\n\n\n\n

I was watching a great series on YouTube by a MotionBuilder animator named Bryan Brewer<\/a>. I highly recommend his series to anyone starting out with MotionBuilder or to anyone who uses MotionBuilder and is looking for tips. While watching the fore mentioned videos, I noticed how nice it was to have a shadow in the scene. I kept looking at the character’s silhouette and shadow’s silhouette, comparing the two and the space they create. <\/p>\n\n\n\n

Creating real time shadows in MotionBuilder has been around for a while but I thought it would be fun to figure out a quick script that would add them to any scene I have open.<\/p>\n\n\n\n

MotionBuilder has a shader called “Live Shadow”, this can be applied to a object and that will allow the object to receive real-time shadows. <\/p>\n\n\n\n

You Can Read Up On MotionBuilder Live Shadow Shader Here. <\/a><\/p>\n\n\n\n

The Script creates a Live Shadow shader, a ground plane which the Live Shadow shader will be applied to, a light that will produce shadows and a sphere used as a controller that can adjust the shadow direction and length within your scene. <\/p>\n\n\n\n

Here is a video demo of the script in action followed by the script itself. I added as many comments to the script as I felt would be needed in hopes to help you break it down.<\/p>\n\n\n
