The renderfarm was told by SideFX to try turning off EXR post processing by setting vm_image_exr_postprocess (http://www.sidefx.com/docs/houdini/props/mantra.html)
I'm going to try that and see if it fixes the issue…

I am rendering out my fluid sim (Foam + Splash) and get this weird glitch with the rendered sequence.

Can anyone suggest a fix?

I ended up exporting the OBJ from C4D as an Alembic File (.abc) and it is working correctly now. I assume that importing the OBJ and Exporting as Alembic caused the issue. I'm sure there is an easy fix, but just keeping everything as Alembic works very well.

Is there any easy way to realign the UV's?
To Export to Alembic into C4D:
On older versions of C4D you have to change the Alembic type to HDF5 rather than the default(Ogawa).

Hello.
I have imported an OBJ file into Houdini.
When I export the geometry as Alembic the geometry looks incorrect.
The poly count is the same. Attached is a screenshot in C4D of the OBJ vs ABC file. Any suggestions on how I can keep the geometry identical when exporting as ABC?

Houdini Indie and Apprentice » Surface Tension - Multiple Flip Solvers?
- byronfillmore
- 13 posts

I am trying to simulate a water droplet falling into a flip tank.
The Water Droplet has surface tension set to 48000 while I would like the flip tank to be set to 48.
How do I simulate the fluid with one Flip Solver that has different surface tension settings?
Can I combine 2 flip solvers?
Thanks in advance.

I am trying to simulate this effect…https://vimeo.com/109020378 [vimeo.com]
I have an emitter that fills a cup and I made the main density 1000 for the water.
I made a small percentage of the emitter a lower density 800 so that the particles would float to the surface.
This is working perfectly.
Next I select a few particles to copy stamp spheres and resize based on pscale. This is not working as expected as the particles seem to be dying and popping. I would like to know if the above example is using a similar method or am I completely on the wrong track?
Thanks in advance for any guidance.

Can anyone suggest how to get the initial state of fluid in a cup with no motion? For example, a cup filled with coffee with no movement of the liquid.
I tried creating a collision object converted to a VDB and then cutting out the cup from the VDB by intersecting another VDB… this creates a perfect cup and fluid that fit perfectly. However, when I start the simulation there is still movement of the fluid. I've tried increasing the resolution and particle separation but nothing seems to do the trick.
Any suggestions other than basically waiting for the simulation to calm the fluid to the point that there is no movement and using that as an initial state?
I would love to know if there is a simple solution that I have not considered.
Thanks in advance.

Technical Discussion » Hqueue Windows - Cannot add windows client

Hello.
I have spent countless hours trying to set a simple 2 machine render farm using Hqueue.
On my first PC (RENDR) I have Houdini Indie & Houdini Hqueue client/server. When I use the local host I can see my client in the window (See attached)
On my second PC (RENDR2) I have Houdini Indie Engine & Houdini Hqueue Client/Server. Again, when I visit localhost:5000 on this machine I can see the client.
I am trying to set it up so that RENDR (PC1) can see RENDR2 (PC2) on the localhost:5000 page.
I have disabled the firewall.
I have changed the shared directory to be identical on both machines.
I have configured the Hqueue client and server to login under each machines user/pass
I have changed the HqueueServer path on both machines to:
hqserver.sharedNetwork.path.windows = \\RENDR2\HoudiniShared
I am getting near the point of giving up as I really don't know what else to try as I have followed the instructions provided by SideFX.
Can anyone assist? Thank in advance.

Hello.
I am a current Houdini Indie Customer.
I am planning to build a small Render Farm (4 PC's) in my office for handling my fluid simulations….
Can you confirm the following versions of Houdini are required to run distributed rendering for fluid/smoke/fire simulations on my farm?
PC1 - Houdini Indie ($199/year)
PC2 - Houdini Engine Indie (Free)
PC3 - Houdini Engine Indie (Free)
PC4 - Houdini Engine Indie (Free)
Thanks in advance.

The solution you suggest does not include any documentation on how to implement it. Could you kindly show the steps to use the module for exporting particles to .prt? Thanks in advance.
Houdini Learning Materials » Clone Static Objects that interact with Particle Fluid

Hello.
I am wondering if someone could point me to a tutorial that can clone 1000 spheres as static objects that will interact with a particle fluid.
Basically I am simulating a liquid pouring into a cylinder filled with 1000 small balls. I need the interaction between the objects and fluid particles to be as accurate as possible.
I'm very new to Houdini so not sure where to start. Any suggestions would be helpful. Thanks in advance.
