Hi there,
I've experienced this issue for a long time, and have no idea how to avoid it. When you fracture a piece of geometry, if you want the shards to be connected, we enable “Connect Inside Edges.” If we were to render the fractured geometry, the geometry would now have visible cracks in it, and would no longer look clean.
The work around that I've used has been to use a switch to switch back to the original geometry(pre-inside edges connected). However, for some animations, the switching method won't help.
I know that for what I'm asking, there probably isn't a simple answer. So if someone has a scene file where this is handled, I'd love to check it out.
Thanks!

I'm pretty sure your problem is the division size parameter on the pyro node in the AutoDopNetwork. Pyro and smoke effects have a default division size of .2. You increased the value to 1, probably for ease of playback. Unfortunately this has a drastic effect on both the movement of the simulation, as well as the appearance. I changed the value to .2, and the effect was a lot better. Experiment with these values to find one that works for you.

Hello! I had an interesting idea for a scene here, but I was only able to achieve the effect I wanted using a very inefficient method. So I was hoping someone could look at my scene file and advise me on how I can make the same effect work in a more user friendly way. As the amount of shards I use increases, the harder it is to manage the network I created. What you will see in the scene file is my only successful attempt at creating the desired animation. There must be some other way of transferring attributes from the points to the shards. Any help would be greatly appreciated.

Hi there,
I'm trying to find the best way to upload my animations online. I currently use youtube and vimeo, and have used Veoh in the past. Vimeo has the best quality, but even that reduces the quality substantially. I was hoping someone could either point me in the right direction of which uploading website to use, or what export settings(from AE or Nuke), that would result in the best quality uploads. Any advice would be much appreciated!! Thanks!

Hi! I figured out the solution. The size of my fractured sim, as well as they fractures themselves, were too small. Increasing the size of the overall sim fixed the problems. I also used particles with my fractures, to save time and memory.

Hi! It looks like the $FF expression changed in H13. What is the equivalent expression for $FF now? Thanks!
Houdini Lounge » Type Properties Window Maximize stuck

Hi there,
I'm encountering this problem when I change the size, at all, of the Type properties window of a digital asset. The window maximizes to full screen, and cannot be minimized or closed. All controls, including the minimize, maximize and close at the top of the screen are cut off, and the accept and save controls at the bottom of the screen also disappear. My only option is to use the window without moving it at all, or maximizing it at all. I tried a re-install with the latest daily build, but the problem persisted. If anyone knows a keystroke that would help me, or a workaround, I would appreciate it.
Thanks!

Hi there,
I'm still trying to figure this problem out to no avail. The drag force isn't working properly with my magnet force, so my fractured pieces refuse to lose velocity after colliding with the ground. I have temporarily disabled the drag force, but feel free to enable it to see the problem. If there is any method you can recommend to bring my shards to a stop after colliding with the ground, I would appreciate it. I also tried adding a VOP Force and animating the velocity to 0 after the collision, but this didn't work as well.
Any recommendations would be appreciated. I have attached the file here.
Cheers

Thanks for the reply! I tried a drag dop, but it was having a really odd reaction to my magnet force. It seemed to blow my magnet force up, increasing the velocity substantially. This is the opposite effect I would expect. I'll try increasing the friction on both objects, as you suggest. Thanks for the tip

Hello!
I have a simulation where a magnet force makes a fractured object explode. After the fractured pieces hit the ground, then continue moving indefinitely. How would you recommend I reduce the velocity of shards after the impact of the collision, so that they come to a stand still.
Thanks!

Thx for the advice. The problem definitely lies in some type of aberrant reflections. I wasn't able to pinpoint the issue, but somehow I was able to avoid it. I'd post the scene file here, but there are files linked outside of the program that would unfortunately defeat the purpose. I'm going to see how my rendering goes, and if I'm unable to avoid the problem, I'll probably return here.
Thanks again for the help Rob. You the man

It looks like the problem mostly disappears when I remove my forced Matte. Not sure why it is occurring, or how I'm going to work around it.

Hello,
I am encountering a problem with my render, where I am experiencing artifacts that I can't account for. Little specs appear in my render all over. I tried disabling my area lights, but that didn't fix the problem. Has anyone seen something like this before? The problem is greatly reduced (but still exists) when I remove the forced Matte from my renderer. I'm attaching a .pic to show an example.
Thanks in advance!

Hi Rob,
What version of Houdini did you use to make your file? If you used H13, I'll need to wait a few days until I upgrade my workstation, to test the file out. I opened it in 12.5 and there were a lot of unrecognized parameters on import.
Thanks!

Thanks Rob.
I experimented with caching the sim after it was created, for ease of playback, though since I encountered this issue, I eliminated that step as I thought that may be where the issue originated. As far as the creation frame values are concerned, I don't recall changing those. Perhaps it has to do with the version of Houdini I am running. I'm going to go through the file you linked and see if the problem still exists on this end.
Thanks for the help Rob!

Hello, I'm encountering this issue where my shattered pieces appear at frame 14, then disappear at frame 16. If I turn off Geometry Velocity Blur, the object appears. No idea what is causing this…
