hi guys,
I'm trying to create a 'fleet' of black orbs to be following someone. I have created an orb using the optics tool, however when I change the colour to black (from the default red), the orb disappears - even on a white background! Why is this and how do I get the colour to be black without it disappearing?

Thanks!

It does that because black translates as transparent... I think?

Try rendering out the optic by itself... no background... include an alpha channel.

Import the rendered optic and use the grade toolset to change it's color.

Optics, by default, are set to a screen composite mode, which would remove any black. You'll need to change the composite mode to get the black to show. I'm guessing Normal will work best for you, but use whichever one suits your needs best.

Click the name of the layer on the timeline, and the Object Attributes will be displayed in the Toolbox. Open the Composite menu and select whichever mode you want to use.

To explain why it does this: the optics are meant to represent 'light'. The brighter the colour the more visible the optic. Black means a complete absence of light, so the optic isn't visible.

Changing the composite method to normal will change it.
