Houdini Indie and Apprentice » Toruses copied to points fall as one object in RBD sim

Not quite sure why you are using the old RBD solver. Here is another quick version using Bullet which is much better suited for this kind of stuff and is faster.

If you use vanilla MatX and not the Karma side of thing sharing shading networks should work just fine between Houdini and Maya. Basically, almost everything works fine nowadays that Maya USD is more mature. However, you can still run into issues if you use Maya vanilla USD, if you go through the Bifrsot Graph and author there you can pretty much accomplish the same thing as Solaris, and is procedural, so keep both DCCs running procedurally if you need to.

There could be a variety of reasons why you are getting different results, such as different MOP versions, it might not be related to MOPs at all and it could RS, without a scene these are just guesses. Your best bet is just caching the end result and rendering.

The path deform has a piece attrib where you can match what you want to deform, so on your trails add a name attrib that matches the pieces that you are copying. Not need for a for each loop.

You need to pin your points on the hair vellum constraint and for that you can use the group expression sop and it has as a snippet code for this "first point of primitive" `vertexprimindex(0, @vtxnum)==0` also make sure you have match animation and depending on your needs you can play with the pin type orient pin type

Is always a good habit to get into to remove attributes or groups that are not in use. For small stuff you won't really notice the difference but when dealing with large data sets or millions of pts, it makes a difference

You need to use the Mops pivot node to change the pivot when using MOPs, if I recall correctly, then the randomize should work as you expect. If you want to visualize it, use the mops visualize frame

Technical Discussion » Transfering scenes from Houdini -> C4D (Redshift) USD?

That all is the hand of how C4D handles USD. Im not a c4d user but I guess you can import USD scenes into it? If so yeah you can probably manipulate, meshes, etc.
Now for shading, I do not think c4d supports that but that will be a better question to ask in the RS forum. I highly doubt that you can edit rs shaders in c4d.
You can save an RS proxy Im sure you know. But you have pretty limited edit capabilities with proxies as well

Sorry to ask the obvious but are you sure this is a poly surface and not is pack yet or a poly soup? Sometimes when you unpack you still need to convert to poly after the fact. If that is not the case, can you post the file in question?

Load the abc in Bifrost and it will work just fine. No need to promote anything either, Bifrost can read all pts, vertex, and prim attributes.

This has nothing to do with Houdini btw. Chaos needs to solve that if you are rendering through the Houdini session.
Usually is much better to set up a batch render for it or use a render manager like deadline or such.
