Tutorial HIP Library

Recommended Posts

I completed the particle energy shockwave tutorial. It's more of an energy shield rather than a shockwave. I have set it up to render with Karma, but XPU can't handle 100,000 particles-per-emission without crashing. The GIF shows 10,000. The tutorial author uses Mantra, which can handle more points. Another option might be to rasterize the particles and render it as a volume.

Can you also share the name of the author and the tutorial name? I'd like to check it out as well cuz it looks great!

I rebuilt the flip pump velocity guide boat wake setup found at this link. This HIP works with the new flip solver workflow and a basic whitewater setup.

I saw a scene on Houdini Blueprints depicting Crag walking through a plane. I thought the concept was nice, but the implementation was missing a feature. This is my rebuild of that scene. The background is now UV mapped in the 16:9 ratio, so you could apply footage to it. The Crag geometry is unpacked to provide a better contour tracking to the geometry shape. Other packed RBDs could take the place of Crag in this setup. The main feature I added was the addition of a primitive group around the edge where the transition takes place. This will allow a separate material to be applied, such as a glow, while still maintaining the background plate.

Thanks a lot @Atom and @Librarian for sharing the files. A small request. Can you also please share the links of the tutorials so that they can be followed along ?

Have you compared with the old classic DOP flip solver @Atom? The resuls looks all very very different like the example below

Nice one man! thanks.
I was wondering how to blend shape that into an infinite ocean? I want to place the camera in such a way I can see the flip sim but also blend it with an infinite ocean which will use a baked spectra for render optimization

Path tracing in Vex with #houdini #houdinifx

This actually works now you probably not want to do this ;)

I worked through the meteor shower tutorial today. The tutorial used Mantra rendering, but I set this HIP file up for OpenGL and Karma output.

OpenGL on the left and Karma on the right:
