Hi

I am having an issues with the Niagara ROP in 18.5.462 using sidefx labs 18.5.499, When I press render nothing happens no errors nothing it just saves a blank file.

when I open the same file in 18.5.408 I can save no problem.

Yep, me too verified. That's why I can't upgrade at this time.
I'm not sure if this useful tool will ever be updated.
I wish the Labs team would simply jump on it and make it part of the tool set.

Thanks for reporting the bug. I'll put it on my to-do list and post a reply here when it's fixed.

Paul merged a pull request from leaping-rhino/niagara_rop_py3 after .499 that should have fixed this issue. Could you try updating Labs to 18.5.510?

Can confirm working with 18.5.514. Thanks for that.

Is there some kind of particle limit with this tool or maybe its an unreal issue? I have a 240 frame sequence when I export the whole thing nothing shows up in unreal but if I do say 100 frames then it shows up fine.

I'm using Houdini 18.5.696, when I hit the render button in the Labs Niagara ROP, nothing happens. How do I fix this?
