Ambiant Occlusion Artefacts

[blackantmaster]

Describe the bug Some artefacts apperas in front of many meshes when the ambiant occlusion from Post processing Stack V2 is active in the Builtin version.

To Reproduce Steps to reproduce the behavior:

1. Create an environment
2. replace the grass shader with nature renderer
3. add post processing stack V2 to the main cam with Ambiant Occlusion Layer.

Expected behavior no artefact

Screenshots

Project(please complete the following information):

• Unity version: 2022.3.1f1
• Render Pipeline: Builtin Shader
• Nature Renderer Version 2022.0.0

System (please complete the following information):

• Platform: Windows
• Graphics API and Version : DirectX11

Additional context Add any other context about the problem here. The artefacts are caused by details mesh, one is mine using custom shader, the other one is the prefab Detaill Grass Variant 2 from the demo folder. If you add Ambiant occlusion to the camera in the demo scenes, and drop your camera bellow the terrain, you will see the artefacts appearing. Other mesh causing problem: White Flowers 01 variant 1, Conifer

and after more work I noticed that the wind effect is moving the mesh but the AO doesn't react as it would

Just a +1 to say I'm also experiencing this!

It looks like the ambient occlusion pass of the shader did not get patched correctly. For the Nature Shaders, can you make sure that you have the latest version installed? You can go to Window > Package Manager (Visual Design Cafe) to check if you have the latest versions.

For your custom shaders, can you check the source code to verify that it was patched correctly according to the documentation. Sometimes the patched shader code ends up in the wrong part of the shader, causing issues like this. If you can't figure out how to manually fix the shader code then feel free to upload it here or use the business contact form to send it privately and I'll take a look at it.
