Multi Camera rendering like NASA app

Hello,

I am currently doing an app where we can move in a house.
The point of view is like a FPS game and I want display a minimap in the bottom left corner.

To create this minimap, I want use an other camera (in orthographic mode) in Blender.
In fact, I want to reproduice both views that can be seen in NASA app :Curiosity.

So, how to renderer a second camera in Blend4Web ?
If it's not possible, how explain NASA succeeded ?

Thanks,

Sorry if i make mistakes, I'm French.

Hi and welcome to the Blend4Web forums!

You can use the render-to-texture feature for this

See also this topic.

Hope this helps!

Thanks a lot, I achieved what I wanted to do.

Just with the first link, it's a little complicated ; but with the .blend in the second link, the topic, I better understood.

So, Thanks. Have a good day.
