      Hello,

      There is this amazing shader on shadertoy called "Bloody" that, if I understand well, is extruding a video feed onto a liquid surface, giving the impression that people are "getting out of the bloody liquid".

      Bloody shadertoy

      I'm having a hard time using shader on my machine, so I have the feeling we could do that with Isadora actors and with a B/W video feed... but how?...

      I can't remember witch actor gives volume to another video depending on luminosity ...

      I have something "ok" with the Displace actor (old CPU actor), but I thing better can be achieved...any idea?

      Thanks for your help!

        You might mean the Rutt Etra its a plugin from the Add-ons page.

          @tease Yeah probably Rutt Etra set to solid I'd say. Can be pretty GPU heavy but worth it!
