Need advice for rendering in MAYA

[feverheat]

Dear everyone , I knew a lot of ppl like you using the Renderman ( the upper class render software), is it difficult to find this software in HK ?

For rendering the object with the shadow , you prefer using the raytrace or Depth map shadow ? hope you can provide the valuable advice. thanks~~

It strange to call Renderman (I guess you're referring to PRman) an "upper-class software". Well it's "upper-class" in price (US$6000/CPU) that's for sure But in the hands of an inexperienced user it can be as "lower-class" as you want it to be (quality-wise). Also, there's very few (less than 5) serious Renderman users in HK. In fact there's very few serious Renderman users in Asia.

For me personally, there's no general preference as to depthmap shadows or raytaced shadows. Different situations call for different approaches. Sometimes I even use negative lights or painted textures to make shadows. But raytraced shadows are generally more convenient.

Ray trace shadow has better quality, but it is slow . Depth map shadow is fast . Shadow from translucent object can be achieve by ray trace shadow only .

Raytraced shadow is not necessarily slower than dm shadow, nor does it always have better quality (you mean it's sharper?). Translucent dm shadows can be done, but you need one more render pass. Computer graphics is all visual tricks.

The biggest difference between a Raytraced soft shadow and a Depth Map shadow is that a Depth Map shadow is evenly soft around its edges.

Raytrace shadow can create a "depth" of the light.
A light casts a hard shadow near an object & a soft shadow far away of the object.
即近實遠虛
