that's way too much effort compared to a texture vs texture. He is turning bitmap into paralax map with near the same quality as displacement at near the same computational cost of bump mapping...

Have you used any - either Max+Fstorm or DECALmachine?
I did, wasn't impressed... and since, haven't find the use for it or a client wanting it yet.

Oh, & BTW one simply pulls the specific decal from the library, applies modifier and animates the move.

Did you see any comparison between the bump and the new paralax bump in fstorm? You telling me this is not impressive?

It is a fake and, like all fake techniques, it has draw backs (for instance the lack of shadows, it may have serious problems if seen trough mirrors and glasses, etc.). At the end of the day is always a trade-off: it may be good to have but you have to renounce to something.

Oh yeah, didn't even noticed it :lol: Corona has it like 2.5 dimensional displacement to save memory... and it saves quite a lot when you got detailed rocky & stoned architectural scene (is mighty helpful, as we tend to exaggerate with the luxurious matter)
