Add post effect only to face inset !

Hello Opey!

This is a great question, and definitely doable by having 2 separate cameras set up in Lens Studio---- a post effect camera dedicated to rendering post effect, then apply the render target from the post effect camera to the main camera. Here's a step-by-step example:

1. Create a Face Insect object under your main Camera, then create another camera called Post Effect Camera and put a post effect under it. 

2. Create a Post Effect Render Target from Resources folder (do not copy paste the original Render Target cause it would not work), then drag the post effect render target into the Render Target slot on your Post Effect Camera.

3. Make sure to sort your render order and layers, it would not work without the right rendering order. Make sure the Post Effect Render Target is on top of the Camera Render Target.

4. Set the layer of your camera to a new layer 'Layer1', (or any layer beneath the layer which your post effect camera is on, in this case it is Default). And remember to set all items in the main camera under the same layer.

Your layer view should look something like this:

5. And now you should get something like this! Pretty close?

6. The reason our face insect object is blacked out is because when we created the new 'Post Effect Render Target', we didn't specify an input. So select your Post Effect Render Target from the Resources folder, and drag 'Device Input Texture' into its Input slot.

7. Now we have a face insect with post effect!~ Woohoo!

Hope this was able to help, let us know if you have any further questions! ;)
