Hi,

I'm currently attempting to create a shader with a panning texture map driving the refraction node for a ripple effect. I have made on of these style shaders before with amplify, but I needed a different one. For some reason, the refraction isn't following what the texture is doing. However, when I plug the same map into the albedo channel, it displays as intended.

I went back to one of my previous shaders and I noticed that one was no longer working either. After having a look at the text code, I noticed that when the shader uses a texture for the refraction slot, it creates a new texcoord. However it doesn't initialize it. In this example, you can see the albedo using texcoord_0 and refraction using the uninitialized texcoord_1.



Is this a bug or am I missing something? Sorry if this has been confusing, Im having difficulty explaining the problem.

Cheers,
Ben

Hello Ben,

Thank you for getting in touch and for taking the time to report this issue!

Would it be possible for you to share with us a shader sample with the issue present?

That would be extremely helpful in helping us pinpoint the exact problem, thanks!

Sure thing, what's the easiest way to upload a file to the forum?

Apparently the 'upload attachment' function doesn't allow shader files to be uploaded.

You can either zip the file, or simply send it through wetransfer to [email protected], thanks!

Ah cool, I'll stick it in a zipped folder then.

Thank you for sending the shader sample, we'll get back in touch as soon as we have any related developments.
