Wall of fire... is it possible?

Unity Engine
1

Hi all.
I am trying to make a large wall of fire that will be moving across the terrain “no need to follow height of terrain”.

I tried using standard particle system assets with different shaders “standard asset shaders” and got it to look really good, but the particles dont show up untill right infront of player, I would like them to show up at the horizon.

I also tried using a cylinder with texture on it but that looked weird.

Do anyone have any idea on how I should continue with this? I really would like it to be a particle system but not sure if that is the best way or if it can be done.

Not sure why they wouldn’t show up at distance… Maybe try setting Min Particle Size in the Renderer module?

I will recreate the particle system tomorrow and record how it looks. Stay tuned :slight_smile:

Here is a short clip of the problem. I have tried to change Min particle size to as hig as 6, still the same.

In the clip you can see that in the first half, I cant see the particles , my clipping planes are set to Far: 1000.

I then set the Clipping planes to Far: 100000 and then I see the particles but the Sun is not visible in game. The sun is visible in the Camera Preview.

I have tried using a second camera that only renders the sun with the clipping planes at Far 1000, but cant seem to get it to work.

Ah ok, so perhaps some kind of far clipping plane issue.

So, are your particles further away from the camera than 1000 units in this case? If so, it is expected that you can’t see them.

This part sounds odd, but I think we would need a bug report to investigate exactly what is causing this to happen.

Thanks :slight_smile:

I got it to work!

I created a extra camera under the FirstPersonCharacter.
I used these settings on that camera:
Clear Flags: Depth only.
Culling Mask: Everything.
Clipping Planes Far 100000.

On the camera in FirstPersonCharacter I used these settings:
Clear Flags: Skybox.
Culling Mask: Everything but the wall of fire.
Clipping Planes Far 1000.

I now see The sun and the wall of fire. :slight_smile:

So if I use 2 cameras and these settings it works and I am not sure if there is a bug or not.
It is strange that the sun is invisible when I look at it with a camera with large Far Clipping Planes like 100000.
