Tried messing with it a bit more. Changing it to an unlit, additive material took it down to 27 'base pass' shader instructions and 111 vertex shader ones. That definitely sounds much more efficient. Anyway - should I sort of disregard the amount of vertex shader instructions, and only pay attention to the other number (59…
So I was just screwing around in UDK, and I made a pretty nice looking material - and then I looked at the statistics. Apparently it is 59 LightEnv shader instructions, and 114 vertex shader instructions. Which sounds afwully high? I tried cutting out things, but it'll only affect the LightEnv figure. The vertex shader…
