Adding Dust and Snow

A question came in from the Boris FX FB group, so I thought to post here. The user wanted to know if there was a way to create “dust particles” in Optics.

While Optics does not have a “particle generator” effect, some of the existing filters can be used to generate elements. Here is an example and a shared Optics Setup.

Dust - you can generate very fine dust or noise with the Aurora effect found in the Lights category. (See image and Swirl params).

And you can use the Grunge filter found in the render category) to create snow and smoke elements. Download Optics Setup.

And in this video, Rickard shows how he uses various filters to generate snow:
