Hello guys, thanks for the responses.

ADK you told me you simplified my asset but you didn't attached it!

Cheers

All I did Javier was decrease the poly count on the internal boolean (the one that produces all the irregular noise/cuts along the y axis) as well decrease the internal sphere count (scatter SOP) and their poly count. Not sure if I saved it but happy to reproduce it if you need. It took too long to cook otherwise.

Not knowing the old shop context too well makes me pretty unaware of these limitations, so knowing that my hard wired functional expectation were at least in the ballpark is a relief. One thing is pretty clear tho , I should have started my Houdini journey eons ago. Thanks again jsmack.

I just quickly tested this with an OBJ and all the booleans / groups do come across.
Different apps will pick these up differently obviously, in LW the groups come in as parts (GIF).
I'd test other apps but my main machine is out of action.

Also, I simplified your test setup, just a lot less polys and scattered points, as it's pretty heavy to play with on my old laptop here.

Thanks for that thorough explanation and great example jsmack. Really appreciated. The aim was mask where the displacement takes place and I was trying to pipe in an attribute for that. Knowing what happens underneath makes it obvious why it didn't work.

Similar download issue happened to me a few weeks back, tried different browsers and even jdownloader as André suggested. Nothing helped and they all timed out at one point or another , but eventually it came goood. No idea why. I'd hazard a guess that it's an AWS issue as that's what the link was to from memory.

Hi there folks,

My very first post seems like such a silly question, but no amount of logic / reading / tutorials seems to point me as to why this is the case so here it goes.

Disclaimer - I'm relatively new to Houdini, month into it, but not 3d, which I've been doing for decades.

This is a very simple setup, box>poly bevel>transform> then time blend held at frame 1 into rest position etc.

Then I simply setup a principled shader and enable noise displacement.
Noise sticks with transformed object - YAY! (top part of GIF)
If I then simply Promote Parameter - Amplitude then the whole thing breaks (bottom part of GIF)
Any parameter it seems?

Why is this the case and what am I doing wrong/ missing as a concept here ?

Cheers
