Unity particle systems: Particle fade/ distance to camera

THendersonVFX

Some friends approached me about making an effect for their project in Unity and I had some questions before I give them an answer and jump into it. They are making a suspense/horror explorer game, and they asked if I could make some ambient fog that fades as you get closer to it. Does Shuriken/Unity have the ability to easily set up some kind of camera distance link to particles? I'd like to have the fog's opacity decrease closer to the camera, and solidify the farther away you get.

I admit I have yet to jump into Unity yet to find out myself (been working in Unreal for a few years) and there was no "Particles" or "VFX" section that I could find in the Unity community forums

Any kind of insight would be helpful for this.

I think this shader does what you need:

Let us know if it works for you.

Thanks! I'll try this out when I can and let you know

Couldn't get this to work, and I don't have time to learn code. Are there nodes in Shader Forge that are equivalent to Unreal's Camera World Position and Object World Position? I already built a mockup in UDK, I just need to transfer the results into Unity.

Shaderforge has World position and Objection position, plus also a depth node. I hope these are all you need:
