In this video we are going to add a few features to our volumetric shader:

  • Directional lighting
  • Self shadowing
  • Ambient/Sky lighting
  • Distance field mesh shadows
  • Scene light linking

Same as the previous video, this is based on a tutorial series made by Ryan Brucks, Principal Technical Artist at Epic Games. Check out his blog at https://shaderbits.com/

Thanks for sharing. Very clear and helpful. Just a small note on the “shadowboxtest” as it was mentioned mapping values to 0.5 to 1 but it seems mapping the values in the range [0,1] to 0 and the values outside the range to 1 (and abov based on distance to the range). Thanks again for this great series.
