Console messages

⚠️ This extension asset requires the latest version of Stylized Water 3 to be installed. A whole slew of errors and issue can be attributed to using an out-of-date version!

Error: CS0117: 'Extension.ID' does not contain a definition for 'RiverModeler'

Again, this extension requires Stylized Water 3.3.0+.

Solution: update the Stylized Water 3 asset to resolve this. And reimport this extension asset from the Package Manager.

Error: Unable to find type StylizedWater3.RiverModeler.RiverGenerationJob+ParticleEmitter

Skipping over the warnings and instructions in the Getting Started section will result in this error.

The extension was imported with one or more script compile errors present, resulting in the VFX Graph now being broken.

Solution: Resolve all script errors and reimport the asset from the Package Manager.

Particle Effects

Particles are all clumped around the pivot point

Due to incorrect project setup the VFX Graph has been permanently broken. Please make sure to install any required package before importing an asset.

Solution: Reimport this extension asset from the Package Manager.

Mesh Generation

Overlapping triangles in tight corners

This is a limitation of the method in which the topology is generated.

Sharp turns are typically to be avoided if visible artefacts are not desired.

When creating a prefab from a river, the mesh disappears when loading it in

Unity saves procedural geometry with the scene file, as each of them are unique. Outside of the scene it was created in (such as in a prefab), the data will be gone.

Solution:

  • Enable the “Rebuild on Start” option
  • Or export the river as an FBX mesh, and use that in the prefab instead
