I’ve become stuck with a problem in the material editor in UE4 and thought I’d ask for some help.
I’ve just started adding Meshes (created in Maya) into my VFX workflow and I’m following ImbueFX’s tutorials for the basics, but I’m having trouble getting soft edges on my Mesh?
Right now I’m using an Additive, Unlit material and a panning texture node to create refraction on a sphere mesh, but I’m trying to get the edges of the sphere to appear soft, or fade out, rather than a harsh circular line. ImbueFX uses a CameraVector and Dot products it with a 3 vector with 1 in blue (Z-axis) to achieve this but it isnt working for me? I’ve tried using Fresnels, 1-x Fresnels and loads of other things but I feel like I’m missing something. Would someone be able to point me to the direction of a tutorial that covers this exactly? Or a step-by-step - I think I’m forgetting something obvious!
I’m very new to VFX and teaching it all myself so any advice would be really appreciated!
