I know you can smart people out there can explain this to me and find a solution for it.
In an animation, I added a simple plane and applied an area light to it. This light needs to fade from 100% to 0%. Interestingly the radient plane disappears BUT the light reflection maintains unchanged on the ground and main object. Logically this reflection needs to dim or fade accordingly to the source light.
Let me attach a sample file for you
The fade animation you're using won't do what you want on its own. You have to couple it with either a Color Fade animation node or a Number Fade animation node using the material graph. Adding one of those will make the light dim out as the panel fades away. See the attached .bip. I updated your file to include a multi-material that has both a Color Fade option and Number Fade option so you can see how they both work. If you want the light to dim but for the plane to remain in the scene, just remove the Fade animation from the plane and use only the Color or Number Fade nodes.
Hi TGS808,
awesome, Ill have a look at it tomorrow. Thank you!
