Re: XSI Zpics and Aftereffect

Hi Luc-Eric,
Thanks for pointing this out to us.
We didn't look hard enough to see the Zpic option....
That probably why the "Zt" is inverted when we renamed to "Zpic"
Is it possible to render the Zpic separately?

Zpics have their advantages.  They are floating point and contain the exact distance to the camera of the each pixel in softimage units, there is no data loss and it’s consistent between frames.   Since they are a dump of the Zbuffer, they are not anti-aliased, but that’s what you need for Z-compositing. Or at least, that’s the best you can do – z-compositing is never great.

Hi Alan,

Thanks for your suggestion we will try out.

Does it have to be zpic? I've had good luck saving the depth

renderchannel/framebuffer of a render as a 16bit *.SGI. Works great.

As for RPF, it apparently needs to be implemented by mental images and

they don't feel like doing so, according to this post:

 This is our first venture in using zpic from XSI and sending to our

 Aftereffect's guy.

 We are using XSI 6.01 and he is using Aftereffect 7.0

 We gave him a pic file and a zpic file to test.

 XSI rendered out a "test.pic" and a "test.zt"

 It didn't work in Aftereffect until we change the zpic file's extention

 to .zpic

 The next problem we have is the zpic data is inverted.

 Anyone else run into this problem or we doing something incorrect here.

 The Aftereffect guy enquired why SXI/MR. doesn't generate RPF (Rich

 Pixel Format) files

 like many other 3D packages.

 Thanks,

 Leoung
