Why does the beta version alter the apearence of several elements (plasma, gases, uranium and plutonium, and several others)? Also why does heat view now show the temperature a couple pixels away from some particles (like fire and plasma) even when ambient heat is turned off?
Even more it now makes spark not look like a hazy glow as it used to be in the default view (called Fire View). Now SPRK instead looks like descreet packets of electricity, just like it used to do in Pressure View and Velocity View modes. Even in Heat View it now shows SPRK as descreete packets. This really will take getting used to, if it ends up making it through beta and ends up in the final release version.
I also noticed that spark is not visible on black wires anymore. That breaks alot of saves that used the "projectile" concept, but adds more hideyness to electronics.
