Replicating Unity's Standard Shader

[sazberryftw]

Hi,

I'm trying to use Amplify to recreate the Unity standard shader so I can have more control over it. I seem to have been able to recreate most of it's features, but there is something off about it. It almost doesn't look as shiny and metallic, despite using the same textures/values.

I couldn't tell if maybe it is to do with the way my Amplify shader is reflecting the skybox? Let me know if you need a screenshot of my Amplify shader nodes.

Hello,

Thank you for getting in touch with us and using the Amplify Shader Editor!

We've just tested on our side with the latest Unity and ASE versions, and everything seems to be working as intended, as you can see in the following screenshot.



Could you share with us which version of Unity and ASE you're using, and send us the shader sample so we can check it out on our side?

On a side note, there are a few things that we cannot fully replicate at the moment, such as detail texture blend mode, which is not a limitation, just small differences in how it is calculated but it wouldn't quite look like the screenshot you've shared.

Hey thanks for replying.

I'm on Unity 5.6.1f1 and Amplify 1.2.1. My material isn't currently using the detail texture node so that is fine. I've attatched the shader, wouldn't let me upload the shader for some reason so I zipped it.

We've tested on Unity 5.6.1f1 with the latest ASE version and everything is working as expected, so updating the Amplify Shader Editor is advised.



The only differences that we noticed were in the Roughness channel, the Standard Shader gets its values straight from the Metallic alpha while your ASE shader used a separate RGBA texture for the Roughness ( Smoothness ), if you connect the alpha from the Metallic map you used in the Standard Shader directly to the Smoothness input, you'll achieve the same results.

Please let us know if this worked out for you, thanks!

I see, when did Amplify get updated? We only purchased it the other week. Anyway I'll take a look thanks. And yes but I purposefully seperated the metallic and the roughness in my shader.

So, in that case, is it working as expected?

Thanks!

Okay thanks for the info. Can't update ASE right now, but once I can I'll check to see if its working as expected. Thanks for the help.
