[Closed] Custom Fog System + Physics Question
I wanted to have fog in my level which only travels along the floor and is about 20-30 cm's high. I tried looking at the ambient fog volumes available which puts fog on the entire level, which is not the desired effect.
Would I have to make a custom particle system in order to achieve such an effect? If you can't quite imagine what I am looking for, here is a video showing off the kind of fog I want to produce:
Now a second question would be, can you make the fog interactive? I'd like to, say, drop a box on top of the fog and the fog will go around the box because of air pressure, stay low because of gravity/mass/physics, disperse, relocate and act like you would expect real fog to do.
And how would I go about doing this? I am very new to particle systems in general and the things I have produced so far are...well lets just say less than desirable :P

Thank you for your question. You can create a Collision module in your particle to set the physics properties of a CPU particle. You can set mass, max collisions, dampening, and delay. A good smoke example can be found in the Content Examples' Effects map and that can give you an idea for how to make your fog have a "rolling" effect. This may be somewhat heavy, but it will give you something close to your desired effect.
Please let me now if there is anything else I can assist you with.

The BluePrint_FogSheet (90° rotated in X-Axxis) is an option for ground Fog as you can see. Not the most beautiful way, but a simple one.
