Hi,
I need help in resolving visual artifacts which only appear intermittently at unpredictable times. These artifacts can be seen in the editor’s viewport and also when deployed on a variety of iOS devices.
I have set up a 3D cylinder in Unity which is created using small cylindrical segments snapped to each other. I have a requirement where the material needs to have specular properties.
I have uploaded two screenshots which are taken from the same exact setup created in Unity. One of the screenshots shows the visual artifacts while the other screenshot doesn’t show the visual artifacts. These visual artifacts randomly appear and can be fixed temporarily in the editor viewport by making changes to either “Optimize Mesh” or “Normals” settings in the mesh files import properties.
However, these artifacts soon randomly appear again in both the editor viewport and devices. I can fix them again temporarily in the editor viewport by reverting any changes I made to “Optimize Mesh” or “Normals” in the mesh files import properties and then the cycle starts again.
How can I fix these visual artifacts which appear randomly?

Note:
- I am using Blender files (.blend) in Unity which are created using Blender v2.80
- I am using Unity 2019.3.0b6 (beta) and above versions
- I won’t be able to use .fbx mesh files instead of .blend files because that would involve too much re-work in this point in the project
