I imported the latest tookit, and build my scene, the error appears. Before I import the toolkit, my scene builds fine.
So I wonder if anyone who ever used this tool ? because the package is updated 19 days ago, No one noticed this problem?
But,I tried "build and preview" button, this works fine , weird
Another question is , the unity seems do not support webGL on mobile device, so the Babylon Toolkit exported scene will run smooth on mobile device ?
