Blend render targets with post effects

  • Hi, Emile Swain!

    Looks like you were doing everything correctly! But there is one tricky part. Anyway I'll include all the steps in case if someone wants to use it too:

    1. Create a Camera and objects, that are rendered to this camera and you want a post effect to be applied to them. 

    2. Add a Post effect rendered to the same Camera

    3. Create New Render Target in Resources. Assign it as a render target of a camera from 1. 

    4. Create new Screen Image in a Scene (New Orthographic camera will be created) Set previously created Render Target as a Texture of an image. Set Stretch Mode to Stretch. We will use this Sprite to render Output From Camera 1 with transparency over the Device Camera Texture 


    5. Now we can see our objects but background is not transparent. To fix this go to Render Target created in 3. and set an Opacity of a Clear color to 0. At this point you'll probably see nothing, so here is a trick: Since we have set a Clear Color to be transparent we actually need shaders to write to the alpha channel. So select a Material of an objects and set Color Mask A parameter to True 


    Now it should work!
