blending between cameras

Hi,

Is it possible to blend between what camera1 sees and what camera2 sees ?
In other words: Fade out what camera1, which was the main camera, sees while fading in what camera2 sees.

 

You can do a render-to-texture of one camera onto a partially transparent plain, and have the other camera look at the plain. (Unity pro only)

I don't know of any other ways.

 

But this isn't animatable right? I mean, the two cameras couldn't both be in motion...could they?

 

wadamw: They could be in motion.

Aras Daniel:
That's basically what I tried.
I would need a 2048*2048 renderTexture and that's not the only renderTextre I need to create all the wanted effects.
So I would end up with at least two 2048*2048 renderTextures or even three if I want to render the blending to another mask-plane (with e.g. holes)... -two renderTextures already push the framerate down to around 15/second since I also need 12 1024*1024 textures in the scene at the same time.

I guess I'll just fade the some objects in/out which should/not be visible in the scene...

Would be cool if the camera would have an optional opacity property to make it possible to blend between different cameras in a future version.

-What's a good workflow to capture only 1 frame of the camera view (like screenshot) and create a texture of it at runtime?

 

I agree. That would be neet.

 

Thanks!
Great. I overlooked that. I'll probably do that then.

That's true. But... what about interactivity ? If I render something to texture it doesn't have any complex interactivity by default like if I use Normalized View Port Rect to e.g. create a split screen.
I was thinking about to create a script which restores the interactivity for rendered textures. I guess the camera functions like ViewportPointToRay and WorldToViewportPoint etc. are a good start to look at... (?)

Good news.

--Though I feel a little bit lost with the RenderTexture functions:

-GetTemporary:
Snapshot what the camera sees for one frame ? Or as long as I didn't use ReleaseTemporary ?

-ReleaseTemporary:
To destroy the temorary created RenderTexture or just to stop GetTemporary ?

How would I render to texture for only one frame ?

 

By "interactivity" I meant basically the clickability.
And by clickability I mean that objects with a collider are clickable with the mouse-cursor and call e.g. the OnMouseDown() function.

RenderTextures which show objects, which are originally clickable, don't have this detailed clickabiliy, just because it's only a texture (one clickable object and not a bunch of them) and not what the camera shows directly on the screen as original (and not rendered to texture before) objects.

Or did I miss something ?

OK. So Create() and Destroy() does basically do the same but these functions are more meant for a longer (than temporary) useage ?

-
And how would I tell the renderTexture to create only one "shot" of what the camera sees and attach it to a plane as texture (which doesn't change again) ?
Would that be a good example when I should use GetTemporary and ReleaseTemporary ?
