How to Import:

   • Open your Blender project.

   • Go to File > Append...

   • Navigate to Laser Grid.blend > Material.

   • Select the materials you want to use in your project and click Append.

   • Alternatively, add the .blend file to your custom Blender Asset Library path.

Applying and customizing:

   • Assign the material to your mesh.

   • In the Shader tab or Material sidebar adjust the custom group inputs like Volume density.

   • If using "laserGrid", remember to apply your object scale (CTRL + A > Apply Scale) for uniform grid distribution.

Engine notes:

   • Cycles: Full volumetric light emission and path-traced depth work out of the box.

   • EEVEE/EEVEE NEXT: Requires an internal/external light source for inner volume scattering, plus Bloom enabled in the compositor.
