Make canvas transparent?

[belugawhale3]

I would like to overlay the canvas over a three.js 3D scene and allow users to draw on the 3D scene. Currently I'm setting the zIndex to overlay the canvas, but its default color is white so its opaque and blocks the three.js scene.

Would be great to set the canvas to be transparent

You can do that by setting the canvasColor prop to transparent.

Here is an example: https://codesandbox.io/s/transparent-canvas-mpsj9w?file=/src/App.tsx
