Render to texture

Unity Engine
1

Hey there

I am making this office environment, and there will be some computerscreens here and there. Now, I thought about making the screen show the view of the main camera, instead of just having a static picture.

I made a new camera, which I made a child of my main camera, so it will follow it around. I then made a new Render Texture, which I render to with the new camera. I then applied this texture to the screens. But…it looks weired. I can see something which looks like stripes in the colors of the environment, but it looks nothing like what I see on my screen. Have I done something wrong? UV’s are right, they showed a static picture before with no problems.

Screenshot: The screen in lower left conor are supposed to show the exact same thing as the main camera.

Just forget it, found the problem. The Render Texture was set to clamp, instead of repeat. Not that I understand at all why this would make a difference???..but repeat did the trick, and everything looks fine now. Thx anyways…:slight_smile:

EDIT: Ah, ofcourse I know why clamp would do this…stupid me. Sorry…

Oh, another thing.
As it is now, I render the same scene twice. Which is kinda…you know. Is there really no way to do it differently? Why would you not be able to both render to the screen, and to a texture? Why this limitation?

Because graphics card can only render into a single thing at a time.
