ShaderTerrainMesh lighting problem with water

Hello, i try to add a basic water on a ShaderTerrainMesh (i use a basic box.egg but i have same issue with cardmaker)
i have an issue when i move the camera, i have a “water position problem” or a light issue, i don’t know.

how can i add a basic water with a stable video when i move the camera ?

It could be a problem with the precision of the depth buffer. Try increasing the near distance on the camera to get better depth precision. You can also add more depth bits, but I’m not sure how that is accomplished with RenderPipeline.

hello, sorry for delay, i was on vacation.
i use the terrain demo (RenderPipeline-Samples/08-Terrain at master · tobspr/RenderPipeline-Samples · GitHub) and i only add a basic plane for simulate water (i will create a water shader in the futur)

i try to set nearfar camera: self.camLens.setNearFar(0.3, 100000.0)
but i have same result.

i tried to disable all renderpipeline plugin et set shadow vars in the pipeline.yml but i have same problem.

edit: i fix the issue by scale object for reduce the size.
