Light Ray Tutorial

H5N1 quick means to add together low-cal ray (god ray) to your artwork is to exercise the "radial zoom blur" filter, which is available inwards almost epitome software. Below is the quick explanation on how to add together low-cal rays using radial zoom blur filter.

Procedural Texture

Instead of epitome the low-cal ray manually, nosotros tin as well as exercise procedural texture to generate low-cal ray. Generally, it tin hold out accomplish alongside simply 2 steps alongside Photoshop, AfterEffects or Blender3D.

1. Generate a procedural texture.
2. Apply radial zoom blur to it.

Photoshop
Generate a procedural cloud(noise) texture. Apply radial zoom blur to it. You volition accept to adapt the contrast/brightness to instruct amend result.



Blender3D
For Blender3D, exercise the procedural cloud texture (or whatever other texture similar Musgrave). Then employ the radial zoom blur via "Directional Blur" node. Remember to alter the "Iteration", "Zooms" value. You tin fifty-fifty add together inwards the "Spin" value if you lot want.



AfterEffects
For AfterEffects, exercise procedural texture from "Fractal Noise". Then employ the radial zoom blur via "Radial Blur" or "CC Radial Blur".

PS! There is a "Sun Beams" node which generate low-cal ray inwards Blender3D. And at that spot is a "CC Lightray" effects which generate low-cal ray inwards AfterEffects.

Animation

Why procedural texture? The primary argue to pick out procedural texture is the mightiness to animate the low-cal ray (Maybe non inwards Photoshop).

In AfterEffects, you lot tin animate the "Evolution" value. In Blender3D, you lot tin starting fourth dimension the texture mapping. All these volition copy an outcome which await similar ray passing through moving clouds.
