XSI and Xstream render passes

[MTM]

Is there a way to have access in XSI to separate passes of the terrain and ecosystem from Vue (I am using XSI 7 and Vue 7.5) with shadows,etc preserved in various passes. It does not appear that the G-buffer or multi-pass information comes through to XSI. I am the same guy who is trying to do this in after effects and after a suggestion from Ami to try RPF files I thought I had an answer, but alas I don't see support in XSI for outputing RPF files.

I would like to render the terrain and plants with different render settings in XSI.

Thanks,

Mike

let me check on this.
I am trying to activate my XSI, but autodesk site was down.
So i will check on monday evening

I was hoping to get an answer by now... I have tried many things including talking to Vue support. Here is where I am. Can you offer additional help? Perhaps you can try what VUe support said and see if you get a better result. This is really frustrating!!!!

Hi Mike,

Vue will generate multipass information only for
what Vue knows, ie. Vue objects. so if you have a XSI ground plane, a
XSI house and a Vue tree, then in the multipass of Vue you'll roughly
get:

- the sky
- the tree color & alpha
- in the shadows channel, you'll see shadows of the XSI house onto the
Vue tree, but not shadows of the XSI house onto the XSI ground plane, or
shadows of the Vue tree onto the XSI ground plane. You'll get this
information only in XSI's multipass.

Hope this helps


Best regards.

What you said sounded reasonable, so I tried it, but....

Here is what I did:
From within XSI I loaded a simple Vue scene (Terrain and ecosystem) and added a sphere and box to XSI. I render in XSI and get what I expected, the Vue ecosystem shadows the XSI objects and XSI objects shadow vuew objects... nice. I had turned on multipass rendering (.tif, separate files) to look for the shadows from XSI objects on the vue objects. When I look at any of the passes (from vue) I see sort of simplistic representations of each pass.... with little, but some correct imaging. Even the color passes are simplistic. I tried looking at the same passes from in the stand alone view of the same scene and the passes look correct.

Please try your suggestion to me with Vue and XSI. It it works, please send me a simple scene I can try.

Thanks

Mike
