  1. fire from small source

    all good ideas, thanks
  2. fire from small source

    thanks so much for your input
  3. fire from small source

    Hello!! I have a simple fire simulation using the smoke solver that is using a bush as a source. Do you guys have any recommendations for sourcing on small objects? The bush is incredibly thin in some areas, so it seems the only solution is to crank up the resolution in volume rasterize attributes and the smoke object. Of course it becomes realllllllly slow. Any other ideas that might help speed things up? Thanks
  4. How do you advect velocity field by ifself?

    I see what your problem is. My recommendation is to first get the shape you want with particles then use that as the source for your density/velocity. Using copy of the velocity limits the use of the other microsolvers and you probably wont get very natural motion. I had a similar problem with gas curve force. I saw a video of someone using chaos groups's phoenix fd emitting fire around a curve and wanted to do the same in hou. After messing around I came to the conclusion that if you want to make pyro/smoke solver move in a specific motion use particles as the source.
  5. I just used a collision source sop paired with static object dop and it seems to work fine. I didn't even add substeps or anything. You can see in this photo the smoke flows around the collision. car_steamUC_post_v0002_fix.hip
  6. Issue with pyro emitted from particles

    haha glad you fixed it
  7. Issue with pyro emitted from particles

    could you post a photo of the problem?
  8. Hi, Question about about viewing vdbs in the viewport. If you have a vdb, and turn up the anti aliasing samples, it causes the vdb to appear "open" in the viewport and you see square patches. The higher the samples the worse it gets. This only affects the viewport, it I convert it back to polygons everything is fine. This doesn't seems to happen in 16.5. Is this intended fuctionality? Thanks
  9. Initial State with Vellum Grains

    In the dopnet there is a output node. You can save to disk the frame you want to be the initial state. On the dopnet node, under simulation use that frame for initial state. Hope this helps.
  10. There is actually an easy way to adjust this. You can just adjust the viewport settings for the template only. (not selectable template) You can take it off ghosted, etc.
  11. I add a color node with the color I want then control click the display for selectable template flag.
  12. Smoke Sim- vel not coming through?

    hello! I made a few changes, I changed the vector type to displacement/velocity/acceleration. The reason it wasnt working was the source volume was set to v (on volume source dop), but it should have been vel to match the vdb : ) hope this helps smoke_sim_vel_mystery_fixed.hipnc
  13. Smoke Sim- vel not coming through?

    could you post scene? kinda hard to say whats wrong with out looking at it.
  14. Assign texture around a point

    hey, not sure if this is what you are talking about, but rohan davli has a tutorial here: https://www.rohandalvi.net/baking one of the textures he makes uses curvature to get scratches and dings.
  15. detangle sop

    thanks : )
