I just ran into the same issue. MPlay wouldn't even launch.

After copoying and pasting all my nodes into a new Houdini file, MPlay launches, but only 2 frames are outputted to the flipbook.

The error at bottom left says: Flipbook Generation Error: Unable to create image /Users...(project path)

I'm on Houdini 18.5.458 on Mac OSX Catalina if that makes any difference.

This is probably not an important feature for SideFX, but I wish it worked!

Thank you BabaJ, I did have a sphere-> scatter-> pointwrangle and it somehow works now as I assume it is supposed to work.

Is there a “run” or “re-cook” button or option anywhere?

hello all, I'm trying to get a simple printf() function to work in VEX… I'm on a mac, running houdini indie 16.5.
I ran the command “hindie” in the houdini terminal, Houdini opens up fine.

Then I created an attribute wrangle and typed printf(“hello world”); but nothing happens. What am I doing wrong?

Hello rcortes9,

did you ever find a solution to this? I'm having a very similar issue. I run the Houdini Terminal app by double-clicking it in the finder. This sets up the environemnt if I understand correctly. I then type “hindie” and it starts Houdini but then crashes:
