Photorealism Tips: Glass Is A Volume (Blender, Houdini, UE5)

Описание: Real glass doesn’t just refract light - it absorbs it. In this video, I’ll show the difference between a simple tinted glass shader and a more realistic setup using volume absorption. You’ll see how volume absorption not only adds density but also controls the glass color, so thick parts look darker and thin parts stay clear. The shaders shown are from Blender, but this technique will work in any renderer that does volumetrics.

If you want your glass renders to look believable, don’t just color the surface, make it a volume!
