I know that I posted this video in another post as an mp4. So here is a vimeo video that shows all the stages for this simulation result! I hope you like it! Thank you! Alejandro

Renderman 22 on Debian/Mint installation issues
Pazuzu replied to rod.vfx.td's topic in Other 3d Packages
The main issue is with the libssl and the Qt version that the installer uses. One thing that worked for me was to install the Qt 5.6.1 and also the openssl-1.0-dev. I hope this helps you! Cheers! Alejandro -
Hello! Here are some test that I did using my Implicit Buoyancy Model! I hope you like it!! Thanks!!

Gracias viejo Hernan! Para eso hay una muy buena referencia, y podrias hacerlo si quieres de esta forma, el problema esque necesitarias tets (seria deformarlos de cierta forma para asi enganhar el tool ya que no salen directamente de FEM) y lastimosamente es una pesadilla en cierta geometria, pero creo que vale la pena pillarlo! Aqui te dejo un link: https://www.sidefx.com/forum/topic/48343/?page=1#post-219429 Saludos, Alejandro

Hey Howard! Sorry about that! Here is the scene, I polyreduced a bit one of the frames of the sim to have a less heavy file to share! By the way, that mesh still has a freeSurface attribute; So you can use that gradient for nice shading effects. I forgot to say that this scene uses Redshift. v2.6.32; H17.459. Cheers!

Hablame en espanhol viejo Hernan, por lo menos pa que practique!! Estoy usando el gradiente del atributo que genero dentro de la simulacion para detectar el FreeSurface; Los MircroRipples en este preview son calculados en simulacion, pero a veces no se contrastan lo suficiente asi que los contrasto a nivel de mesh tambien para que se noten mas aun, ya que al rasterizar las particulas se pierden si no se usa una resulucion muy alta, por ende opte tambien en tener una solucion que no necesite resoluciones muy altas para hacerlos mas notorios. En este preview podes notarlos directamente en las particulas! Saludos /,,/ /,,/ crown_v004.mp4

Thanks Atom! For this retime I used an old tool that I developed years ago to do almost the same as the new retime tool, the main differences are the nice interpolation options for attributes that the new H17 one has, mine just have linear as interpolation option, so I'll migrate very soon to that one.

Here is another test using a last iteration of my tools to do small scale stuff. This time, now is possible to art direct how much do you want to break a sheet into drops and tendrils, and there are some Micro Ripples on the sheets that are relative to the fluid speed and curvature at some portions of the main fluid body! oil_details_shading_cam01_v001.mp4 Thank you!

This is an amazing node that can help you a lot!!!! I think is also part of the Vellum post process, if I'm not wrong! http://www.sidefx.com/docs/houdini/nodes/sop/detangle.html Cheers, Alejandro

I think this is a very nice starting point to understand better the "inner workings".

I think Mantra is faster when rendering volumes, but the main issue is when you need multiple-scatter; Right now the path tracing alternative to point clouds is extremely slow in comparison with Arnold for example. Lets hope that H17 surprise us with some improvements for Mantra in volumetric rendering.

multiple volumes used as AOV for main volume
Pazuzu replied to Jesper Rahlff's topic in General Houdini Questions
Yeah I know! I was meaning that not directly, you need to tweak first to make it functional. Even when you tried to render that's what the command line tells you! I didn't explain my self correctly! -

Pazuzu replied to Jesper Rahlff's topic in General Houdini Questions
Sorry but that's not possible! Because Mantra will not find the path to the node. -
multiple volumes used as AOV for main volume
Pazuzu replied to Jesper Rahlff's topic in General Houdini Questions
Hi, Here is an example file to create custom aovs for different volumes, the workflow is a bit cumbersome because you can't reference the volumes directly from sops but from a geometry file. The main thing is to activate your hero container to sample the volume aovs. I hope it helps you! Thanks, Alejandro volumeAOVs.hip -
Tranfer Animation from one object to another (abc to vdb mesh)
Pazuzu replied to ParticleSkull's topic in General Houdini Questions
Hey Alvaro! Here is a very simple way to track a transform that it has been defined in sops or at geo level. I hope it helps! Cheers, Alejandro RnD_copy.tansformation.v1.01_aeb.hiplc
