So it seems to be something with my attribute being a point attribute. I tried filling it in the transform like your detail attribute example, but it doesn't like the syntax.

I tried doing that and it just turns green and stays at 0. My scale attribute is updating each frame so I guess that's why it doesn't work?

This is what it would look like with a transform node (except you cant use a custom attribute for uniform scale).

Hello, is it possible to use the xform vop to scale an object uniformly, while keeping its position (pivot)?
I've tried doing it in vex and with a transform node, but neither worked.
The transform node would have worked, except you can't drive the uniform scale parameter with an attribute.

For some reason the attribute doesn’t come through. Maybe it’s something with initialization pre sim or something.
Ended up using a wrangle in the sim based on active and current frame and it worked really well.

Maybe this is a dumb question, but I haven't been able to solve it.
Is it possible to get an age attribute from an RBD sim like a POP sim would have? I've tried different wrangle code in the sim and post sim, but nothing is working right.
Thanks

Ok, the issue is fixed now!
I ended up using the static-geo-uv-transfer method, and that worked out fine.
Thanks so much for the help, I will be sharing the final shot within the next 2 weeks on my website and LinkedIn , hope you get to see it.

@toadstorm,
I am trying drive the Base Texture UV property.
I looked for an “baseN” but I didn't see any on my material.
Here a simple file with just the material I am using so you can check sit the nodes im using. Let me know what I am missing.
Thanks.

Thanks @toadstorm,
I'm not quite sure what you mean by the “lookup position”, in my first image example, where would I plug it in? I have the rest binded already in the image below.

HI there, I'm working on a shot where a chunk of geometry is UV unwrapped based on the camera perspective. The texture works fine until the geometry moves and then it swims because it is aligned with the camera view.
Now I have used the rest node some in the past and it worse fines to hold the texture on a frame but I have only been able to use with the UV Cords node. I am using a custom material with a bind for an AOV and I need to use the rest, is that possible? I haven't been able to find any tutorials or help docs explaining how to make this work, o I thought I would turn to you guys for expert help.
The screenshots below have the examples of what my setups are using.
I really appreciate all ideas and help you can give!

Right. I was trying that one out next. The shadow matte is an Arnold shader, right? I need to render the scene in Mantra.

I'm trying out the file but still can't find any way to utilize the data.
The very best that I can get from it is the result shown.
That is by adding the sphere (and rubber toy for visualization) as forced phantoms and the grid as a forced object.
What am I missing here?

I have been trying both the shadow matte Mantra shaders (“shading” and “shading utilities”), but I don't know how to output the shadow pass from it.
I have a basic scene setup to show my workflow, please let me know what I am missing in the process. The sphere is going to cast the shadow on the grid.
I applied a standard shader to the sphere, and the shadow matte to the grid.

Hi there, I need to create a shadow pass in Houdini 17.5 and I'm pretty new to the shadow extracting process. After a bunch of trail and error and not being able to locate a good tutorial on the topic, I thought I would ask for help here.
What I am looking for is basically a Mantra version of Arnold's Shadow Matte node. It sounds like the process to get a shadow layer out of Mantra is quite tedious, but I just haven't been able to locate anywhere where it is explained, or at least laid out, how to make one.
I really appreciate all the help you have; I'm counting on you guys!

Hi, I am sure this is is an easy answer to answer, but I can't seem to find how to batch file caches together so they cache one after another.
Basically, so that when I let stuff cache overnight that it goes in sort of a chain-like method, if that makes sense.
I know you can batch render ROPs together, and so I want to do that exact same idea but with caches.
All ideas are greatly appreciated!
Thanks!
