Incorrect Tessellation shadow

Postby minh01218834066 » Tue Jun 12, 2018 5:20 pm

I follow this https://unity3d.com/es/learn/tutorials/topics/asset-store/introduction-amplify-shader-editor tutorial on unity (2018.1.0f2 with ASE 1.5.3)

With default setup (nothing relate to World Normal of Vertex Normal function) it works perfect:

But if we add in some nodes that are related to functions like World Normal and Vertex Normal, It will screw up the shadow of Tessellation

The case is, Triplanar Sampler (which is related to World Normal function) is in use in the second test, and it will screw up the shadow.

Even thing like this will make the shadow of Tessellation go wrong (Vertex Normal multiply by zero and connect to Metallic - I can't understand why?).

Thank you.

Hello, thank you for getting in touch and for your support!

Apologies but I'm having trouble fully understanding the issue, I've tested both the example in the tutorial and the node setup you've shared in your screenshot, and everything seems to be working as expected on my end.

Would you mind sending us a sample with the issue present, together with additional details regarding the expected results of your setup? I might've missed something in my tests, so a sample would be extremely helpful in order to debug the issue with the exact same conditions.

Thanks!
