Viewport into another map

[Nimzog]

Hello

 

I need to make a "portal" that looks into another map. I looked through the forums and all the comments are either vague or dated. I have a general idea on how : put something(the portal) in front of my player and on the material/display area of the portal display what a camera in the other map sees. I have no idea on how to link said camera to the material/display area. Any input or guidelines are welcome (if possible in c++ please)

Look up render targets. You render the view from your second world into a texture / material that you apply in the first world. There is an example for LUA that can be easily ported to C++:

This is one of the topic I was calling dated almost no commands are recognizable in 3.x

 

And thank you xtreampb it helped a lot in making this portal a reality

But that is for 3.x. what is not working with it?

this line here looks totally alien to me:

 

self.MainCamera:SetMatrix(self.TrackingPivot:GetMatrix())

 

and all the matrix related lines

It sets the matrix ..rotation, position and scale, all in one command.
