What's the difference between the three types of billbord: base, impostor and cloud?

I can't find any explanation in docs.

Many thanks!

Hello @songtao.han!

All these three options in the Create menu create a Billboard object with the corresponding material assigned:

• billboards_base - universal base material for groups of billboards;
• billboards_impostor_base - base material for impostors, supports sampling different regions of textures based on viewing angle;
• billboards_cloud_base - intended to simulate simple shaded clouds.

These materials have different parameters and rendered differently based on their applications, you can find more details in the given articles and the Art Samples demo.

Thanks!
