Simple Particles Special Effect

I am starting with simple special effects of hero skills, to show hit direction, similar to:

But my approach only works from top down camera view.

This is my current progress (PG):

Also I wonder if these could be done with babylon particle system, but I guess those would be quite advanced only for experts?

Let me add @PatrickRyan as he is a VFX wizard

@Takemura, if I am understanding the effects in the samples you posted, you are looking for a swipe trail effect or some sort of spin attack trail effect in the first image. In the second image it looks like some sort of cloud effect that is distorting the background in some sort of heat distortion effect. I’m not too familiar with Black Desert and so I have not seen their attack FX.

You are correct in that these are more complex FX, as they will need several techniques blended together to look correct. There will also be some custom shaders and/or post process techniques to complete the looks.

The only example I have of particle effects in combination with shader effects like this is this demo showing some animated shader effects in combination with some particle systems. I don’t have anything to show weapon trails like these. However, it has been on my list for a while to work up examples of this type of effect. I will build an example of a couple simple techniques for this type of system. Give me a little time to work something up.
