This simple Unity asset provides a few components to render a shadow onto a render texture so that the render texture can be used with Blob Shadow Projector. Blob Shadow Projector is usually used for dropping a round blurry shadow which is not suitable for a skinned mesh object. This asset enables a projector to drop a dynamic shadow which is perfect for skinned mesh objects.

In addition, version 1.2.0 introduced a new feature which enables a Projector to project shadows on transparent surfaces. For more details, see the documentation page: Project shadows on transparent objects

Dynamic Shadow Projector can be a good alternative of shadowmap for mobile platform, because it doesn't require depth textures, and it works on almost all devices. However, Blob Shadow Projector can be very slow on mobile platform. If you got a performance problem, please try our another asset, Fast Shadow Receiver. It really improves the performance of Blob Shadow Projector.
