Hello, We have just submitted a new asset to the Particle Systems category, called Fantastic Fires: https://www.assetstore.unity3d.com/#!/content/39390 While it's in the queue to be approved, I figured I would post the video right here and open the discussion for feedback/suggestions. The effect doesn't actually use a lot of particles, or animation sheets. Most of the work is done in the shader itself (and a little bit of scripting as well). WebPlayer Demo here: http://yearseventeen.com/fireeffectshader/webplayerbuild.html Thanks!
It's definitely meant to be, but I don't have a mobile dev environment set up to give you benchmark or anything like that. I can tell you that it works with SM3, and even runs on WebGL. WebGL build here: http://yearseventeen.com/FireEffectShaderGL/index.html (First Person Controls are a bit difficult, I think the webgl player isn't able to capture the mouse properly...)
I'd be more than happy to test on Windows Phone 8.1 as well if you wanted to create a Windows Phone build.
@imtrobin I don't think you'll be able to move around in the scene, but at least you should see a bunch of fires on screen: http://yearseventeen.com/FireEffectShader.apk @Dustin Horne, It's still going through approval, sorry. I just tried building a Windows Phone 8.1 package, and apparently I need to be running Windows 8 to be able to do that.
Ahh yes, because you need the Windows SDK. You could install Windows 10 on a virtual machine along with the 8.1 SDK and build it that way but that would be a lot of work.
