Welcome to DirtJam!

DirtJam is a Blender shader node group for CYCLES and EEVEE, designed to give you unparalleled creative control over the look of glass, liquid, gel, or other transmissive surfaces. With the latest updates for Blender 4.3, DirtJam now offers continuous dispersion, delivering smoother and more realistic prismatic effects than the previous version. Enhanced grime placement calculations and volumetric rendering provide a higher level of detail and authenticity, while adjusted light paths of the render setup boost the realism of volumetric rendering and transmission effects.

Whether you're crafting crystal-clear surfaces or experimenting with alien-like textures, DirtJam offers the versatility you need for stunning results.
