  1. Hi, I recently decided to recreate an old Maya project in Houdini. For that I had to export animated mesh from M to H so I used alembic. The 960f was 119Mb I did some modifications and tried exporting it as bgeo but it exploded to 106Gb so I tried abc which turned out to be 35Gb. And yes i added some attributes, subdivided few things and stuff, but it still seemed too much for the changes I made so I decided to explore. I exported animated abc from M (2019) of just 11f (step 0.25f) and that was 94Mb. I opened the abc in H with basic alembic node (default H18 settings) and export that with rop_alembic_output node straight from the alembic read node, with the same frame range & step. I've tried different formats (HDF5 and Ogawa (used by Maya) ) and settings here but all had pretty much the same size results of 1.5Gb. I didn't find any settings that would relay to compression or anything like that. Is it the same for you guys too? Does anyone have an explanation of this and perhaps a solution/idea how to reduce the abc size from H? Thanks Martin --------- Houdini 18.0.349 Maya 2019
  2. Hey guys, I have a few questions regarding Caching elements using the BGEO format. Im wondering what the advantages or disadvantages are when using the bgeo.sc compression vs bgeo without compression. Are there other benefits to using sc, other than smaller file sizes? also are there disadvantages, such as it taking longer for playback because of the compression on larger files? Lastly are there advantages or disadvantages in using other compression formats like gz and others? Appreciate any help on this topic. Thanks, Jordan
  3. Hello, I was wondering if anyone had any suggestions as to why my flip fluid sim seems to "compress" as my container moves. Any help would be appreciated. Thanks!

  5. simulation question

    Hi I would want to approximately simulate around 200 frames of pyro sim. 1)I have my explosion simed to disk using a file dop for around 25 frames.There was a power problem and Now again if I want to simulate frames from frame 26. does this means I have to wait again till frame 25 to simulate frame 26 second question is as the simulation range increases towards 40 the bgeo file size is too much even with bgeo.gz compression.and for every frame after frame 40 it takes around 3 hours easily to write out the bgeo files. Is there a better way to optimize this.Almost for every sim I encounter the above two situations Would be great if someone could help me out.
