Shows how much I need to re-orient my thinking from the maya way. I was thinking ‘this shouldn’t be so hard. let’s see, a simple gradient… already stumped...’ ha well, I obviously have more reading and watching to do. Leaving the comfort of the shelf tools shows how much fundamental stuff I need to wrap my head around.
One thing that it’s different is that I’m used to the maya node editor, where you’re making explicit connections with the visual pipes showing what you’ve done. In houdini it feels like you’re just connecting things so that THEN you can define which attributes are explicitly connected or flow through.

>> Hello. Iâm playing around with the Ocean Waves shelf tool. I need to be down low, with fairly large waves. Works great, and I have a look that Iâm dialing in, but what I need to do is control the height of the waves as they get close to the camera. Imagine a low camera looking across the ocean. I just want to fake the height close to camera so I donât get huge swells rolling past. Not reality, but thatâs ok. In maya for instance I might take a gradient and layer it up so that white = some negative multiplier and black = whatever the node is generating. Doesnât have to be that, but some way that I can visually adjust and control the ocean surface.
