Compatible Nuke versions: 8.0 or later
Compatibility: Linux, Mac, Windows
Example Video: http://vimeo.com/96521727
Info:
This node uses the uncodumented node called 'ParticleToImage' to relight your 3D scene using Blink Script. I have included 2 examples along with the node.
The Node:
The node takes 3 inputs.
Particles (Any particle node or stream of nodes)
Camera
Scene3D (A Scene or 3D geometry)
Additional info:
There is no hard limit on how many particles / lights you can have but the ammount your GFX-card can handle.
The light intensity is controlled by the particle size, so big particles will emit more light than small ones.
You should easily be able to change the node to input 2D render passes enstead of Nuke Geo.
Release History:
v1.1 - The camera input would only accept a direct link between the camera and the node. This behaviour have been fixed and you can use dots and axises again.
