Access UNITY_VERTEX_INPUT_INSTANCE_ID

[mrmcd]

Hi ASE Community!

I created a shader that is drawn by Graphics.DrawMeshInstanced, and I need to have different variables for the instances. To differentiate in the shader I need to access UNITY_VERTEX_INPUT_INSTANCE_ID to use it as array index for my custom data.

How can I access UNITY_VERTEX_INPUT_INSTANCE_ID?

Best regards,

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

You're in luck, as we've just added an 'Instance ID' node in a build that was released this week:

Oh wow, guess I'm super lucky. Thanks for the answer.

Out of curiosity, was it impossible before?

No problem, happy to help!

I don't think that there was any way to access that data before, not even outside of the scope of our editor, which is also why I said in my previous reply that you were in luck.

Please let us know if you have any further questions, thanks!
