Hi All! Total Octane and Cinema 4D newbie here, deciding to use this coronavirus self-isolation as a chance to learn something new!
At this point I'm just messing around, experimenting, following tutorials, reading the documentation etc., but there's one thing I'm trying to do which has me stumped. I imagine it's just because I've tried to dive straight in without getting a full understanding of things, so I bet I'm missing something obvious, but hopefully you guys can help me with this.
I'm trying to create an Emissive object, a plane in particular, which has a gradient opacity falloff. Essentially I want a bar of bright light which fades away, the blue light in this piece by Sarpar Baran is a good example: https://www.instagram.com/p/B9cElwOHKz3/
I thought this wouldn't be too hard, so I got into the node editor and made a Blackbody Emissive material with a gradient Falloffmap linked to the Opacity. In the Material Editor it looks exactly what I was aiming for! But as you can see in the screenshot here: https://imgur.com/a/Qm3QeyS , when I apply this material to a plane object, the object's opacity isn't affected by the material. What am I missing to be able to apply the opacity falloff of my material to the object it's applied to? I've been searching around for how to do this but haven't found anything yet, so any help will be greatly appreciated!
Cheers,
Josh
