Wow!! great! i got the caustics:lightbulb working in meters, all i played was with the decay!!, Thanks for telling that:beer: … lol i was bumping up the photon samples and playing with sampling radius…
And about enabling “generate caustics” in the properties for the light, well i guess it is for the objects that i want to generate caustic right, i am saying this because it didn’t have any effect in my scene either on or off for the the light, the render output was the same!:surprised
and same thing goes for photon shader!!! well actully very new to mental ray so not familiar with all the shaders and stuff!!
For the caustics I just played around with the decay and it did fine!! i didn’t need to change anything else.
For instance if i dont want this particular light to generate caustics i can simply set its caustics photons to 0, rather than using the generate caustics under light properties, which for some reason does not have any effect. Correct me if wrong:blush:
Sorry, guess i said wrong about reactor, well i meant to say was that the value you give for
World Scale This value is specified in world units. It specifies what distance in 3ds max units represents one meter in your reactor world, and hence determines the size of every object in your simulation. So what ever system units you are working in, you can always define 1 Meter in The Havok physics engine(Reactor) = What Units in Max.
Same goes for the cloth fx, it has its own way of defining scaling of the objects! rather than taking directly the system units into consideration.
I though there must me something like that in Mental Ray too.
Anyways thanks for pointing that out.
