Hello,
I get a big difference in the rendering of my scene when I try on another computer.
Apparently, what renders different are meshes with particle shader, namely the particle/Additive and the particle/Alpha Blended.
It’s like the particle don’t add properly, it looks grey, looks like it’s clamped or somehing…
here, you can see the difference I’m talking about :
The reflection (or refraction) of the water looks a bit different aswell

So far, it only renders fine on my computer … everywhere I tried, it looks different.
You can try the demo here : https://db.tt/MCP2bUtK
My computer is kinda old (and shitty) but Unity runs fine, and I though as long as you can launch it, you’ll get the same render on every computer 
Cpu : AMD Athlon 2.2 Ghz
Graphic Card (Integrated) : NVidia GeForce 6100
and that graphic card doesn’t support pixel shader 3 
(is it because of that ??)
Cpu doesn’t matter here so I guess it’s because of my graphic card ?
Is there anyway I can fix this to get the good render everywhere ?
Force something specific about that in Unity ? idk
Thank you !
