Hello all,
I’m trying to use the Crok Snow 3D lightbox in Action in Batch but it doesn’t seem to work. I just don’t get any image at all.
Can anyone confirm if it’s broken or maybe give me a steer as to what I might be missing?
I’ve been looking at the three ways in flame vid here…
… and can’t see that I’m doing anything wrong.
Stock lightbox effects work fine.
Cheers!
Old Matchbox versions sometimes get degraded with upgrades to the software. It’s not you. With a little help from Claude, you might be able to upgrade the matchbox as it’s not a compiled mx but just a glsl shader.
Aaah ok cool. Thanks man.
Presumably that would be about updating the XML part that hooks the shader into the flame interface… anyway, I’ll take a look.
I’ve been putting off taking the plunge into this matchbox world for years so this might be just what I needed! I’ll report back if I get anywhere.
Thanks again.
If updating the MX works, and if you still have issues, feel free to reach out. It’s been a while, but I have used the crock volume metric shaders in action before, and the setup can be unclear.
I did put in about an hour. Gave Cluade working lightbox samples like acid, flames, bokeh, starfield, etc…and asked it to fix snow3d. Couldn’t make it work as a lightbox. I told it to write it from scratch but that was futile as well.
If you’re looking at creating snow…I’m not saying particles, but Particles!
Yeah, and the snow particles preset isn’t bad, and I’ve used it in production.
@Sinan well, yeah, I’m not surprised you’d say that! Totally blown away by what you do with particles in Flame. Thanks for all the tutorials.
The presets are decent but I quickly turn them into garbage when I try to adapt them.
I find the whole system really really abstract compared to almost everything else in Flame. I love using a clever expression to get the job done but the particle syntax is just so inaccessible.
I can’t imagine they’ll ever address it but something more user friendly would be nice!
Another thing I need to sit and properly get my head around in downtime.
Cheers!
The idea of getting something working quickly with a tracked camera in Action and dof / motion blur is a real incentive.
I’ll have a play and reach out if I get anywhere useful
I took a look at this and fixed it* – it was riddled with uninitialized variables being used which made the math go nuts and basically produce NaN.
I uploaded it back to the Matchbook, so go grab a fresh copy from there (https://logic-matchbook.org)
*Although I don’t know what visual results it produced pre-Vulcan and I don’t have an old enough version of Flame installed to find out, it’s at least drawing something other than black now 
Oh that’s great!
Nice one, I’ll take a look.
Many thanks!
Works in 2025.2.2
@ManChicken many thanks for your time and effort.
Not quite enough parameters to make it work for what I need but pretty interesting how it interacts with cameras in 3d space.
I’ll try adapting AFX_Snow_Machine to have that functionality.
Or just suck it up and learn particles better!
Cheers!
Ping me if you need a specific setup Owen. We can discuss and I can help setting up a system you can then easily manipulate.
