Houdini Niagara Updates Nov. 20, 2020, 6:15 a.m.
Hi There
I am trying to create a looping particle animation and there seems to be a weird delay in the beginning of animation. I have reduced my data to 1 point and 10 frames and created a super simple position sampler, but the problem still presists.
In Particle Update my ‘Test Script’ just reads the position value of the particle 1 at frame 1 (the position is 0,0,0 here) and passes it on to the Houdini particle position parameter. But I have to go to approx. 0.03 on the timeline before the particle shows up.
WHAT am I not understanding here?!?
Cheers
Jacob

How to I read a key-value dictionary from an expression? Nov. 7, 2020, 11:22 a.m.
Thank you both of you for the answers.
I ended up using the pythonexprs solution but tested out the JSON one too just to learn some more :-)
one (unrelated) question zengchen, is there a deeper meaning why you use a string parameter () instead of just directly using a string in ? just curious :-)

chs("json")
json_loads(chs("json"), 0);

How to I read a key-value dictionary from an expression? Nov. 6, 2020, 8:51 a.m.
As the title says, I am trying to use a key-value dictionary parameter to drive another parameter via an expression but I can't seem to make it work?
I haven't been able to find any information regarding this, I'm afraid.
