Use this toolset to make your particles cast light onto geometry using the new ParticlesToImage node.
8.0 or later
Linux, Mac, Windows
14 Jun 2014

Example Video:



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)


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.

Is there a cap at 26x26? I was trying this out and it didn't seem like I could get the map any bigger than that.

This is super cool, though!

Hmm, Linux Nuke 10.5v7 the particle lights are rendered from a more zoomed in camera than the camera fed into.

So I can't line up my particle lights with the original geo.

The camera inside is not the same focal length as the camera plugged into it, so you can put the camera you want inside and patch around it to make it match, but it's odd

Cool tool! I'm wondering if there is any way to use this in conjunction with the ParticleCache node?
