water now introduces another camera

[shadmar]

How can I tell them apart in my post effect stack?

[Rick]

I haven't played with water yet but I assume if another camera is there then there is some kind of script making that that we can ourselves modify (and Josh could also to make it more official so not sure if you are indirectly asking him to do so in your above statement) where another key is added to that camera that you check for. Give it a type key and after you find name = camera or object = camera check the type key for more specifics on what camera it is.

[Josh]

A second camera for reflections is automatically created. The reflection camera does not apply any post-effects. Post-effects are applied to the scene after water is rendered, so the water blends in seamlessly with the scene.

[Rick]

I think he's saying that he has a process that loops over all entities in a scene looking for the camera to apply something to it. Now when he does that he's seeing multiple cameras. He needs to know which camera is which.

[Josh]

Look for one with a negative scale on the Y axis. That's the reflection camera.

[shadmar]

Ok, but

 

uniform vec3 cameraposition;

seems to return reflection camera position.

 

and if you test for camara position in lua-posteffect file's Render() function it also returns refelectioncam pos.

[Josh]

You are correct. Fixing that now.

[shadmar]

Yes, I tested against cameramatrix[1][1] to figure out if it was the reflectioncam.

For clipping geometry shader for correct reflections, you can use:

if (cameramatrix[1][1] >= 0.0 || geometryposition.y > waterlevel ) { .. render stuff made by geometry .. }
