Hi, i have an issues with this script - for me #ifdef LIGHTWEIGHT_LIGHTING_INCLUDED is always false for some reason. What i should do to manage it ? Using Unity 2018.3.2f1 / Lightweight RP 4.8.0 / Shader Graph 4.8.0

Hey SarkKlimento,
if you update your LWRP to 4.9.0, this modified node should do the trick. Message me if you have problems; I'll try to respond as soon as I'm able.

Hi, I'm getting 26 errors keeping me from making a build, on SG 4.10.0 - Perhaps this needs another update?
hi! i am getting 26 errors as well... in 4.6.0 / 4.8.0 / 4.10.0 I tested them all and there is no way to make a build :(
