Hello!

I'm a new (really new) Houdini user and I am desperately trying to work through a problem I just cannot seem to solve. I've been following this tutorial:

https://www.youtube.com/watch?v=SjKIWQY7tzo [youtube.com]

To make a realistic beach scene. Then, I've taken the results of that, creating a VDB from that, and then trying to output to an Alembic file. However, at the end of this process Maya cannot import it, saying “// Error: line 1: particleShape1: Object not found for -object flag.”. If I try to re-import the file into Houdini, it comes up completely blank.

Again, I'm sure I'm doing something catastrophically stupid but I'm really new to Houdini and there's a lot to process here. Any help would be absolutely invaluable.

Hi , without following the tutorial, do you have a simple scene I can have to look at.The standard workflow is export the surfaced mesh with colour attributes for vel etc.

Does Maya even support VDB in alembic files?

After spending another 10 hours or so on this problem I think I've got the main problem worked out – I can now import the actual mesh into Maya. I think what I was doing beforehand was trying to export the voxels which, obviously, wasn't working super well.

That being said, I still can't solve another problem. Basically I'm trying to create a wave crashing on a beach that's able to loop infinitely in time for a video I'm making. I need to render it in Maya, so I have to export it as polygons which I think I've now accomplished. But the looping in time aspect is now causing problems, as I can't seem to make it seamlessly loop, despite following another separate tutorial on making flames loop in Houdini. I realize it's not quite the same but, as an extreme newbie, this is pretty much the best I could find on this topic…

Thats never going to work , flip is driven by points and you need that unique $ID

Hm. I guess I don't understand – probably entirely due to my newbie-ness with Houdini. Well, either way, thanks for the help! I'll keep messing with it and I'll try to see if I can come up with something…
