Virtual texture shadow artifacts

Hello, I’m experimenting with virtual textures to blend the landscape material with other objects. But I’m getting strange artefacts. Any idea how to fix this?

Thank you.

Those look like typical shadow bias artifacts. You can play with shadow bias settings or use models with more geometry to avoid them.

I played with the shadow bias settings to no effect.

I set my mesh to disable Cast Shadow. Not sure if that will be an option in your case, but worked for me
