Reflection? Is it really impossible?
Hello, is it really impossible in unity free version to make a realtime reflection? Someone told me that everything can be done that is in the Pro version, i just have to write some extra lines. But how to get a texture from the camera without eating the cpu? I know i could duplicate and rotate the entire scene under the surface of the plane and make it semitransparent, change the lighting and add it to a different layer. But this technique is very limited, because of the objects under the water. RenderTexture and RenderToCubemap is only working in pro, i wasnt able to work around it with screenshots, thats just eats my frames away. So what would be the right approach? Cuda? Shaders? Or something else? Can someone help me?
You can buy it on a pay monthly scheme now, which might help...
Thx for the information, but first i want to find out what i'm capable of in the free version and i dont want to give up either. I just cant find a way to get the camera image without killing the cpu, but this seems like an easy task.
Well, when it's said that everything is possible in the free version, that doesn't mean everything runs as smooth as with pro. That would make pro pretty pointless ;)
However you don't need to manually duplicate the geometry. Look at this:

They simply used a two-pass shader where one pass renders the normal world and the second pass the reflection. The second pass simply inverts the y axis and clamps it to be below the water level.
Do you know how much is this cost(in fps)? But i think i can do reflections now.
