Make an object fade to transparent at edges
I’m trying to have an object gradually fall off to transparent at its edges and be solid in the middle . It seemed like a good idea to select a boundary loop and set a soft vertex map and then use the map in the material’s alpha. But it seems that the vertex map it either fully on or off for the alpha.
Is it possible to do this or should I go and export a uv map? It seems like something that should be easy.
Many thanks,
John

a vertex map should fade across the poly until the next vertex so it depends on your geometry

I forgot to say that I was trying to add the alpha to an already transparent object (transparency ticked with refraction etc). The problem seems to have been something to do with my absorption colour being set to a non-white colour. The soft vertex map is working now but doesn’t look how I was hoping as the refraction doesn’t fall like the colour channel does. You can still clearly see the edges of the objects.
Has anyone got any ideas how to represent rich, coloured jams or liquids, where you have light playing around within a viscous liquid that is itself within a glass jar? Although the liquid is going to be static, I’ve got to animate a camera move on this and it’s got to look really good but I want to avoid a massive render hit.
Thanks for any ideas.

Is there are a specific liquid you’re trying to create? Can you post a sample photo or link to a photo of what you’re looking for?
