curious lang ako kung vray din ba gamit nila or scanline hehe, feel ko rin kasi gumawa ng mga scenes gaya sa mga films for hobby lang

i got to know from a friend (who used to work with sidefx studio) and works in the CG / film industry...
that Mantra (Houdini's own render engine) was used to render some sequences in Transformers.
