How can I go about creating a map ie: press the m key and bring up a map of my landscape?

I assume that I have to do it with a camera just not real sure how to go about this. Seems like a secret on the internet to do so lol…or I just am not wording the question right. But any help would be greatly appreciated.

Like this?

Isnt it quite resource intensive to do it this way? or am I wrong and this is really the only way to do it?

Because it’s a render target? Is there another way?

Because you’re essentially rendering the who map twice? Or am I wrong?

No, it’s like having two cameras. It’s the writing it to the texture that’s expensive.
