Blocky pyro after rendering Nov. 25, 2021, 6:30 p.m.

There are couple of things i have noticed which possible all contribute in some degree:

  • your density values are super high. You source in density with ADD operation with x10 scale. On top you are also emit density from flame with a x35 scale. That's a lot! And on top you are multiplying that by x3 for the render.
  • I adjusted some of the settings, along with reducing the expansion, which i realised was making the simulation expand too much.
  • the rasterized source volume is rather blocky as well. I also made some adjustments there.
  • You have enabled Velocity Blur on the geo, but you also have to enable Allow Motion Blur on the Mantra node.

Let me know if it works for you. (I edited the file in 19.0.445 but later i realised you are on 18.5, but that should not really matter at the end)

It is a bit hard to tell from the image.

You said you are using Mantra right?

What are your maximum volume values? Are you using scattering on the pyro bake volume? What is your Blur Downsample value?

Do you have a scene file to share?

Also I couldn't find any tutorial or article about how to load older caches
We have updated the docs with a great deal of info, which is worth to go through.

https://www.sidefx.com/docs/houdini/nodes/sop/filecache.html [www.sidefx.com]

Alos if you type in youtube, "houdini 19 filecache", it should bring up a pretty cool cgforge tutorial and the hive presentation that explains the node in more detail and what are the benefits using it.
