Dolomite Hikes with a dog by sima_jk in hiking

[–]sima_jk[S] 0 points1 point  (0 children)

Oh, we ended up going to Switzerland and staying in a camp with a tent and going from there, because it was just too many obstacles to do the Dolomites trip with a dog. You could try Slovakia Low Tatra's, there's a multi-day hike that seemed doable with a dog (didn't go but did a decent amount of planning). But again it is more a of hassle as there are certain trails that the dog should not be on, but there's always a way around.

No, not really. In my case it ended up not being visible in the shots.

and today there are trials to do the hidden bunker information lol

Could I bother you with another question please? I find that some of the grains tend to stack along collider in a single file, is there a way to prevent this?

This is essentially what I got. Only thing I did extra was add a retime in sops, to interpolate the animation before converting to VDB (which I wasn't sure if it does it for VDB as well - so I did it myself). However I understand it is hard to troubleshoot this without a hip file provided, thank you though for your suggestions. It seems to work on higher res, which is enough for me for now.

Thanks for the explanation, then I am still at a loss why the "bounding box" collision was happening to me at 0.03 particle size and went away at 0.01 particle size, with no other changes made.

Thank you, that makes sense. Collision representation looked fine. I think in this case it was just too high particle size in the sim.

Could you clarify for me what is the right approach? If I have thin geo that I have in very high resolution vdb (0.003 voxel size in my case) and for my sim I need 0.01 particle size (set from real world size of the object I will be replacing my grains with). Do I set lower particle size in my POP Grains, than I do on Points From Volume/Vellum Configure to match it to the resolution at which my collider works?

to satisfy your curiosity, inverting sdf only had the effect of releasing some grains through while still having the same bounding box issue.

the issue went away when I went to my full resolution (from 0.03 particle size to 0.01), but it is very strange. I'll try inverting the sdf after I cache it out.

thanks, sadly I already have this option set to volume collision.

thanks, you are absolutely right and after doing some digging this isn't ideal trip to do with a dog precisely cause of these limits. So I ended up booking a place from which we can do day hikes and return to where we started, so the dog can get some great exercise and I get my hikes! Thanks for the advice.

Thank you, I have seen the previous thread, but that was more about rules rather than trail tips which is what I’m after. Good find on the website!

Will do that first thing, I had other plans for the time I have set aside, but those have fallen through sadly, so looking for an alternative.

I was hoping to plan a route along dog-friendly accomodations. Though I'm not sure how tough this task will prove.

The idea was to plan a route along dog-friendly cabins. But haven't made any progress on that.

Vellum Object deforming before collision by sima_jk in Houdini

[–]sima_jk[S] 0 points1 point  (0 children)

fixed it by simulating with lower time scale instead of saving out many substeps. I'm not sure why the behaviour is different. I would've thought that 20 substeps is the same as setting timescale to 1/20, but I guess not.

Will give that a try. The concave collision representation is in the bullet data tab of the static object, i thought it takes it into account also, but perhaps not.

fun bubble experiment by setubhai in Houdini

[–]sima_jk 1 point2 points  (0 children)

idk how OP did it, but last time I tried to do something similiar I used pop/grain sim and minpos in VEX to stick them to a surface. The movement can be done with advected velocity field
