Texture looks fuzzy/grainy in my Billboard Material, MSAA anti-aliasing

Im trying to make this material that whatever you move the camera it stays oriented AND scaled to the camera.

So it looks always the same.

However, the texture looks like it’s flickering a lot as you move around.

I’m with MSAA anti-aliasing, thats the one i need to use in my project.

Can anyone help with this?

Maybe a mip issue? Try setting the UI texture group for your texture may help, or force nomipmaps. In the material you can force mip level 0, in your Param2d node change mipvaluemode to mipvalue, then plug a 0 constant into the level that shows up on the node.

So the solution is to set both the Texture2DArray and the Texture to MipMaps Blur1.
Then in the material, control the resolution dynamically using the Mip Levels
