This thread is for uses of cubemaps. I think they could be used on scopes when you aren't zoomed in. To just look at the scope's green/blue/red ball and see a projection of what's in front of you. What do ya'll think?

I'll have what he's having.

Hmm...on second thought I'll just sit here and enjoy my beer.

You'll seriously need to increase your explanation. Most of the threads you post are either offensive, or make no sense.

I don't think a cubemap would be necessary. You need a "screenshot" of what the scope is seeing, not a 3d representation. I think you'd be better CopyRecting the center of the screen about some square texture size (256x256, perhaps), and then scaling this texture up so you have that refraction effect (that objects appear distorted, bigger when you see a lens from far away - distance from eye to scope when you're not holding the gun ready to take a shot, that is).

@Kryzon So you mean to create an extra camera, parent it to the gun, set the zoom value a bit freeky, then copyrect what it is seeing to a 256x256 texture, then assign the texture to the ball?

@ gizy.. no need to texture it to a ball. Setting camerazoom cam,2 should do the trick, then just render it just like any other camera. I assume this is for rumbling darkness, am I right?

To be honest, nope, but it was one of my failed ideas for the project. And as soon as I get it to work (I'm trying different ways right now), I will be happy to give it to the project :D

Best to copyrect. Else you'll have a flat viewport.

oops I messed up on my post earlier... do camerazoom cam,.3 or something like that. Then draw a circle around it to mask out the edges and look like a scope.

Hey, that's not a bad idea Nate. When you zoom to a small value, the field-of-view would get "compressed" or whatever and it should give the appearance of round lens. Render that, copyrect it to a texture and there you have it.
