World Building [RELEASED!] InfiniRIVER ✅ - Real time Fluid based water simulator

InfiniRIVER is the new Fluid based water simulator for Unity by ARTnGAME.

The system can emulate the interaction of water with scene objects in real time using a fluid solver and do so in a global or local way for versatility and cover of all use cases.

InfiniRIVER will be soon released and will be in Beta for some time until all features are full realized. The base fluid system is production ready and more work on usability and control of the effect will be added in the various Beta stages for more options.

The system will be in lower price for Sky Master ULTIMATE and InfiniGRASS users, on release make sure to buy one of those assets first and then upgrade to InfiniRIVER for maximum discount.

Features (All pipelines):
- Fluid based water simulation for detailed interaction of scene objects with water
- River mesh generator
- FFT based water and waves shader
- World space and local space choice for versatile water placement and interaction modes
- Caustics (Standard Pipeline - URP)
- Advanced water shader with refraction, cubemap reflection, Sub Surface Scattering
- Dynamic Water ripples and trails simulation
- Multiple sample demos of water - lava simulation
- Fluid based driven 3D particle module
- Fluid and interactive water enabled ground materials

Bonus features:
- Parallax shader (Standard Pipeline)
- Triplanar shader for rocks (Standard Pipeline)
- Randomized Stone generator

Roadmap (Some of the features are TBD):
- Adapt HDRP Decal shader to cast the caustic texture properly
- Convert parallax sample shader to URP-HDRP (TBD)
- Add Delauney based tesselation to river mesh generator
- Add river branching and Terrain river curving
- Add more options in river mash maker
- Make easier to adapt the fluid simulation water flow direction
- Add underwater rendering (TBD)
- Add slope based component for automatic waterfall creation
- Add general flow component using flow maps
- Add real time reflections

InfiniRIVER - Dynamic Fluid Simulator, work in progress on adapting the system for use with the upcoming InfiniSPLAT asset.

The integration is planned to allow two things ideally, provide the InfiniSPLAT with the global flow simulation to define rivers dynamically and the 2D flow with vortexes simulation to allow fully realistic true fluid simulation in the water flow locally, given feedback of the splat map from InfiniSPLAT to define the obstacles for the flow.

Hi, is this integration available to download ? I want to create a flow of the river to the sea and looks ideal for this purpose.

 

Hi,

This is already possible, the Oceanis water has a decal input with displacement and scale control and you can plug there either the fluid solver texture or the combine fluid and water ripple-caustics solver texture from InfiniRIVER to the fluid slot in the Oceanis material to get the above result.

A sample of the combination will also be included in the combined demos that are planned to be included in the Environment Building Bundle asset. I can also send this scene for direct reference.
