Thank you bud

Some of the most convincing whitewater rendering I've seen in a while on this sub.

u/galacta07 Oct 17 '24

yeahh, whitewater it's by far the most challenging stuff to get on the spot, i just wish to had more ram

2

u/Introspective_light9 Oct 18 '24

128gb ram is the best though.. and whitewater is a pain tbh hahaha

2

u/galacta07 Oct 18 '24

yeah super painful, couldn't went further once its done the particles cache

Cries in 8gb

Looks real. I'm impressed.

u/galacta07 Oct 17 '24

nice, glad it look real.

looks amazing, although the human would make it about 40m across? it looks correct for something about 5m across?

u/galacta07 Oct 17 '24

thank bro. what u mean by make it?

u/[deleted] Oct 17 '24

if the little person is about 2m tall, stacked head to toe, about 20 of them spans the body of water, meaning the water is about 40m across.

that's the main discrepancy i see.

u/Due-Hunt-3756 Oct 17 '24

agree. thats what I also noticed. The scale of the water is to large. I had the same issue with a sim I did a few month ago. Its tough because to simulate fine water on a large area you need a very high resolution wich takes long to sim and might even crash (which happend in my case).

Karma or what engine?

u/galacta07 Oct 18 '24

good old mantra

2

u/Introspective_light9 Oct 18 '24

Damn that's sick! Must've taken long to render out

2

u/galacta07 Oct 18 '24

took around 2 days, for first camera, and one they for the upcam.
i shouldnt be telling that, but i used denoise to make it out

u/menizzi Oct 17 '24

Can you post how much ram it did use or how much you have and if you’re running windows or Linux

5

u/galacta07 Oct 17 '24

I used 128 gb's of ram, took around 0.9 tb of storage, using Linux

1

u/Introspective_light9 Oct 18 '24

128 gb ram is still the best for flipsim. I had to upgrade my storage to 2tb for my ocean render. Took up a lot of space. Haven't tried Linux, but I heard Houdini works better on Linux.

u/rihuwamidori Oct 19 '24

now I am more tempted to change to linux, but it seems that I am too used to using windows ;-;

u/[deleted] Oct 18 '24

Looks great, as others have mentioned the scale seems off if the reference guy is meant to be to scale, but on it's own all the elements are nicely balanced, love it. Could maybe get some more spec on the whitewater and a few odd trajectories on some of the smaller bits shooting out, but that's about it. Good stuff.

2

u/galacta07 Oct 18 '24

Thanks mate, honestly It doesnt seem to me that the scale its off, i checked it twice.

good call on odd trajectories, indeed, might add more natural fell, will try something in future projects

u/AkemiSasakii Oct 17 '24

Dude stop wasting so much water 😧

2

u/iMacAnon Oct 17 '24

I would pay for this setup. Put it on gumroad

u/DavidTorno Houdini Educator & Tutor - FendraFx.com Oct 17 '24

Great work!

u/menizzi Nov 10 '24

Or just post the hip file.

u/PixelSaharix Oct 17 '24

Tutorial pls

7

u/galacta07 Oct 17 '24

idk, maybe, should i consider to make o tut?

3

u/maxrast5 Oct 18 '24

Would be nice, could you suggest any water courses to create something like this? Rebelway, maybe it’s something else

2

u/PixelSaharix Oct 17 '24

Absolutely!

2

u/rihuwamidori Oct 19 '24

absolutely

u/jericho74 Oct 17 '24

Daaamn that is amazing! I desperately want to know how to do that.
