Can you point me to this example file ? I could not find it ..

Really interesting presentation of a paper about Multiple-Scattering Microfacet BSDFs

Anyone here using Houdini on huge core count machines?
dulo replied to Kardonn's topic in General Houdini Questions
I am using a 64 Core opteron system with 256Gig of ram. Its great for rendering which really scales very well, but but simulation and cooking seldom uses more than 20% of CPU. Rendering most of the time goes up to 98% .. but sops , pops, ... not so much .. ( at least with H14. had no time to play with H15 till now .. ) -
Just solved the problem by using and object merging the vdb from the glass object instead of doing the vdb conversion inside of the fluid geo.
-
Hi I have altered the HIP file this thread provided to move the collision glass around. My question is: Can I avoid rebuilding the VDB of the glass in each frame ? Can I just transform the VDB from frame 1 to match the movement ? The shape of the glass doesnt change so I would guess that it should be possible. fluidGlass.hip

How to render sharp, crystal clear volumes?
dulo replied to magneto's topic in Lighting & Rendering + Solaris!
Interesting. I really didn't know about this option.Does it generate intermediate polygons or does it really render the isosurface? Thanks for the tip ! -

dulo replied to magneto's topic in Lighting & Rendering + Solaris!
I guess something like sdf surface rendering in 3dcoat would be the way to go .. else you would have to have insanely highres volumes .. -
Very nice indeed !! You pan on building an orbolt asset ?
-
Of course I could try to fake it, by emitting air bubbles at the opening of the bottle and add a rotational force inside of the bottle and add a pulsating force which holds back the fluid from time to time to allow air to flow back into the bottle, but I wondered if this could be possible to simulate in houdini ..
-
Has someone an Idea how to simulate the backflow of air in a bottle which gets poured out ? Do I have to create some kind of airfield inside and around the bottle ? Has someone already implemented that kind of effect ?
-
Maybe everybody except me already knew, but I was really surprised when I realized that it was possible to copy node networks from one instance of houdini into another with ctrl-c ctrl-v !! Just wanted to let the world know about this fascinating feature ;-)
-
wow .. just checked out the bitbucket repo .. great work .. I hope this project continues or sidefx comes up with their own native version !!
-
Seems to work now. Was the Root Object set directly to the export object .. thanks a lot !
-
I just want to write one transforming object ( wire simulation ) into an alembic file to use it as vertex cache in lightwave. I always get some weird message about the object not being in the same object network .. look at the screenshot. What does this message mean and what can I do about it ??
-
If a node fails to cook I get this nice error message with middle mouse click on the affected node. How can I copy this error message into clipboard, or how can I get those messages into a log file or an email ??
