Hi,
I tried using the standard assets Image affect Edge Detect Normals on my Android game, performance is very bad… if I turn that off my game performs well, does anyone know if there is a mobile friendly edge detect shader or image effect available? I would like to use that for my mobile game.
Thanks for any help with this.
This also happened to me. Have you found a solution or an alternative?
Sure, I was doing this for a desktop to mobile game conversion, with the idea that with a line renderer effect I would not have to load any textures , thus saving performance, and gie it a unique look 
That part worked quite well, I removed all my textures etc, only had one material or all objects, also had to reduce the poly count loads, so that was a mission…
I think the approach to take is to make a little objects in the scene that will draw lines, the less the line renderer draws on camera the better., just optimise your game as much as possible.
I tested my game on some of my own android devices, seems to be playable, but its still not perfect (one day I want to revisit and finalise it), see here: https://play.google.com/store/apps/details?id=khos.games.noseat2 , its a bike trial game, so quite niche, but I think it is amazing
PS have you seen the assets you can get for this, they might help you?
Thank you for the reply. So you are using line renderers to make this effect right. Also i am unfamiliar with the asset. Can i contact you somewhere else?
Yes I’m using line renderer. Is that what you want to achieve? What do you mean contact me elsewhere? e.g. email?
