How do I import unity 5 free PBS(Physically based shading) into unity 4 pro since I don’t want to pay for the $750 upgrade to unity 5 pro I know this is highly possible
And is this possible with GI(Global Illumination)
It’s not possible, because they use completely different GI and shading systems. However, you can find some great PBS packages on the forum, like Antonov Suit and Lux, which are also compatible with Beast lightmaps.
