Question: How to make this view aligned dissipation texture?

[VFXPixel]

Hi, I’m trying to recreate the effect shown at 0:10 of this video: [Mark Eaton \ VFX Technical Reel 2017 on Vimeo]

I’ve managed to create view-aligned textures that look 2D (they are facing towards the camera), aswell as the depthfade he shows.

What I can’t figure out is how he creates the mask that makes each sphere fade facing towards the camera dissipate?

I’m using Unreal Engine 4.

many thanks! ~

There is a built in Material Function in Unreal called “ScreenAlignedUVs” that will help you get this kind of result. Just add that to your material and plug it in to your TextureSample for UVs. You can input a Vector 2 into the MF to control the XY scale of the texture.
