This is quite easy. Load a Mega Bezel base preset and save it with a different name.
You will see something like this when you open the preset in a text editor.
#reference "shaders_slang/bezel/Mega_Bezel/Presets/Base_CRT_Presets/MBZ__3__STD__GDV.slangp"
Then you add the graphic as the background layer like this.
#reference "shaders_slang/bezel/Mega_Bezel/Presets/Base_CRT_Presets/MBZ__3__STD__GDV.slangp"
BackgroundImage = "%path_to_image%/myimage.png"
If you separate your reflective screen you can add it as the screen reflection image layer.
#reference "shaders_slang/bezel/Mega_Bezel/Presets/Base_CRT_Presets/MBZ__3__STD__GDV.slangp"
BackgroundImage = "%path_to_image%/myimage.png"
TubeStaticReflectionImage = "%path_to_image%/MyRefelctionImage.png"
You could also separate the TV from the background and add it as an independent layer.
Yes, that is one of the basic features, along with color, inner & outer corner radius, outer curvature radius, etc.
Work on getting your graphic working and we can speak more.
Feel free to PM me.
One more thing, you won’t need the bezel and screen portions of your image, just the TV like this.
