Could we have the following render passes added to Texture Sheet?

Depth and Flow?

I use these passes plus the ones already in Texture Sheet a lot. Having all of them conveniently in one place would be EXTREMELY helpful!!

If they couldn't all be combined into Texture Sheet, an additional ROP just for Depth would be great!!

Hi. Can you provide more information about what you mean by depth and flow? Are you already doing this with your own ROP?
And by depth do you mean a normalized value from 0 - 1? That can be inaccurate when working with volumes.
Is flow something different than the motion vectors ROP?
DRiz
Yea flow is the same as motion vector. So I am already rendering these using the motion vector
ROP. SO, it would be nice to have all this in one ROP, not important.

Yes. I am not quite sure how to do this, I know it involves Pz but no more than that.. I am still learning. I am just trying to get a pipeline down. I had recently used FumeFX for fluid simulations and I had a plugin in 3dsmax that did diffuse, alpha, normal,and depth passes (it calculated the distance of the volumes center from the camera to get a usable 0-1 value) all at a push of a button, so now I am at a loss.

There's no benefit other than convenience of having that all in one ROP. The setups are different and still require separate renders.

And you've just answered your own question. You can bring the Pz image into COPs and divide by the distance from the camera to the center of the object.

So i guess you are just assuming that I somehow inherently know how to make this happen as someone who is learning the program for the first time. I am having trouble figuring that out. This was why I was asking for help in the forum.


Oh wait, I asked how to do depth passes in a different post, this is a request post.. My bad.

Fair enough. Makes sense.

I'm not making any assumptions about what you know. I appreciate that you're learning and a lot of this is still new. But what have you done to try and find an answer to your question? The forum is littered with people asking the same thing and the community responding in various ways. Have you taken the time to search the forum for those threads? A quick search came up with these:

And that last one has a link to a video that explains how Pz works in Houdini. https://vimeo.com/6580446 [vimeo.com]

Yea I forgot this was a Texture Sheet request post. My bad!
