Is it possible to create a reusable-but-modifiable material? 2025年2月2日12:58
I have several objects (using Solaris/Karma) that will have very similar materials but a few things will need to vary (such as uv tiling count). Is it possible to create something like a material instance which I could use for each object and have a few parameters(/inputs?) that can be tweaked per object, but most of the fine-tuning can be changed once at the "source" and propagate across all of the instances (like in UE)? I tried collapsing the texturing nodes into a subnet and promoting the parameters that need to be tweaked as subnet inputs, and then creating a reference copy of the subnet, but that didn't seem to work. (Possibly it was from me creating the reference copy, then having to cut-and-paste it into the new material).
If what needed to be tweaked were just something like color I could make the adjustable parameters point attributes on the models and read them in. Would that just be the best way to go? Create an attribute that would then be read in to drive the UV tiling frequency?

Can't get chramps to work with POP curve force 2025年1月11日10:14
I can't get the pop curve forces (scalefollow, scalesuction, scaleorbit) to work with chramps based on a normalized age attribute. The vexpressions work if I enter other variables/attributes/values, just not ramps. I don't have this problem with other pop forces (i.e. wind or drag), which handle the ramps beautifully. Any idea what I'm doing wrong?
Edit: SOLVED! (Thanks to Toadstorm on the Houdini Discord.) Turns out POP Curve Force is apparently a fundamentally different thing than POP wind and POP drag, in that the Vexpressions don't live in the same place on the node as the forces (or something like that). I made the force multiplier, ramped and all, earlier in the chain on the same POP wrangle where I created the normalized age attribute, and called that new attribute instead, and it works.
Hopefully I'm not the only person to ever have this problem, and this post lives on as salvation to some poor soul in the future, instead of an enduring legacy of my daftness.

Camera background image misaligned 2025年1月3日21:42
Found it, in case someone else runs into this: in the imported camera's properties (within the Alembic xform subnet)there are "screen window x/y" parameters, which were purple. I removed the expressions and replaced them with 0 and now it lines up just right!
