TETHYS
Water on the surface.
Wetness in the fabric.
The native surface-liquid solver for Cloth neXt. TETHYS models how water flows across a surface, is absorbed into a material and evaporates over time.
Currently for GAIA testers. Your existing GAIA access covers TETHYS.
More than a wet surface.
Water on a material and water inside it are different states. TETHYS tracks surface liquid and material saturation separately.
- Flow across the surface
- Surface water moves across the mesh. Material settings describe its mobility, repellency and retention.
- Absorb and spread
- Absorption moves water into the material. Capacity and capillary transport describe how much it can hold and how moisture spreads.
- Dry over time
- Evaporation is part of the solve, so wetness can change throughout a sequence.
Native computation.
A Blender workflow.
TETHYS is bundled with Cloth neXt. The add-on prepares the bake and starts the native engine; the engine computes the wetness sequence and writes the result cache.
A dedicated surface-liquid solver
TETHYS handles surface liquid and material wetness. AETHER remains the Core Engine for cloth; GAIA is the Extended Engine for simulation research.
Built around material behaviour
Absorption, capacity, repellency, wicking, retention and evaporation describe how a material responds to water.
One GAIA invitation.
TETHYS included.
GAIA is currently invite-only. If your PolyWorks account has GAIA access, it also has access to TETHYS.
Use your existing account in the add-on. There is no separate TETHYS registration or activation. Buying Cloth neXt on Superhive does not change your GAIA eligibility.
