Keyer Plane with dissolve transition shader effect

 

Hi,

I would like to know if there is a way to customized the keyer plane with a custom dissolve effect, the idea is to have the green screen keyed person dissolve transition into the stage.

Reference of transition like so.

Hi,

Currently there is no easy way to do it, but you can editor your camera compound (that you probably use) to achieve this effect.

(however I have to warn you: if you open a camera compound then it will not be updated in that specific scene next time you update Aximmetry so you have to manually update it)


To apply an effect on the billboard image, you should do the following:

1. Open your scene.

2. Right-click on the camera compound ("VirtualCam_Unreal_A-B_Preview_3-Cam" in this example), select "Edit Compound In-Place" in the context menu and then double click on the compound to get inside it.

3. Right-click on the "INPUT %N=1" compound, select "Edit Compound In-Place" in the context menu and then double click on the compound to get inside it.
By modifying "INPUT %N=1", you will able to apply your effect on the first input. If you need it for other inputs, you should do these same steps but with the "INPUT %N=2" or "INPUT %N=3" compounds.

4. Double click on the compound named "Line %N" to get inside it.

5. Find the module named "Adjuster %N" here.

You can apply your effect here by modifying the video in the wire running from the "Keyer %N" compound's "Out" pin to the "Adjuster %N" compound's "Video" pin.
As an example, this is how you would apply a simple rectangular mask:

It would look like this:

Of course you can add an effect after the Adjuster as well.
You might want to create different effect for the color and the alpha channels. In this case you can use Alpha Splitter and Alpha Merger modules to get (and set) the color and alpha channels. (do not confuse it with the Alpha Split and Alpha Merge modules)
