How to use light shafts properly?

#1

I was excited to try the nice light shafts to create volumetric effects, but no matter how I slice it, it doesn’t show anything!
Is there any trick or proper workflow to enable it?

Thanks!

Seriously??? An advertised feature without a sample or simple documentation or even any reply??!
Good job!

I’m not sure exactly either, but.
Are you adding the post effect? It’s split in component to make shaft and a post effect to render them.

Hi @jay3d

There are several steps to enable light shafts in your scene.

  1. Enable the feature in GraphicsCompositor asset (select ForwardRenderer which the game entry point is using and set the feature from None to Light Shafts)

  2. Add a light shaft component AND light shaft bounding volume to your directional light entity. Make sure the bounding volume has a proper model set up (you can use the procedural models) and correctly references the light shaft component. If you want to scale the entity and increase the bounding volume, it’s a good idea to separate the entities (don’t scale the directional light entity).

Play with the settings of the lights and the light shaft components. You will also need proper environment, preferably dark, in order to get good results.

Let me know if this works for you.

(We are working on the documentation for this feature, should be up soon with more detailed step-by-step instructions.)
