Animated or Displaced Wireframe Material is noisy/dithered

Hello there,

I was just messing about an experimenting when I came across this issue. I have a material that is animating vertex displacement (not tessellated) using two panning noise maps lerped.

Here’s how the material is rendering in the viewport (excuse overuse of fringing, really overdoing the 80s grid look)

I have to keep the camera moving in order to keep it rendering correctly, as soon as the camera stops moving it dissolves.

Here it is rendering in the material editor perfectly fine

I thought it might have been an issue with the lighting so I put it in an empty scene with no lights and made the material glow and it still resulted the same.

Here’s the material set up:

Of course the material renders just fine when the displacement isn’t involved.

Am I missing something or is this a bug?

Hi Axi5 -

It looks to be a result of the Temporal AA, you should be able to check Responsive AA to true in the Material Attributes and get a much better viewport render of your wireframe.

Thank You

Brilliant thanks!

Hi Eric, the Responsive AA option is only available for Translucent materials though? For non trans materials what should I do?
