Bifrost Graph Tests

Hi.

I thought I'd share some of the tests I've been making while getting to grips with the  bifrost graph, mainly MPM sims.

I've tried to make sure that I can take each graph to the rendering stage so to get a complete idea of the workflow. As a result I generally keep the resolutions fairly low as I currently have time constraints for how long I can sim, I've seen posts about hopefully being able to stop and restart file caching in future releases which I'm looking forward to.

 

I have a question.

Is it currently possible to apply different shaders to seperate air sources in an aero sim?

Wow those are really great tests!

Would be awsome if you could share more info on how you build these!

Hi cg_uglo.

Thanks for the feedback.

 

I've made a couple of videos showing how I went about making the crumbling man animation.


This one runs through the graph set up

This one goes through setting up the character to bring it into bifrost.

I hope people find them useful. I should say my bifrost knowledge is fairly rough and ready so apologies if I get my facts wrong.

Thanks for the tutorials. I wish there was more information out there structured as clearly as these ones!

 

Can't wait for more 😉

Great work!

Regarding your question about attaching different shaders to different aero sources, this is possible. I have attached an example maya scene file. The scene sets up two different sources, each one having a custom property (color1 and color2). Then the aero object is output twice and a different Arnold shader attached to each to create smoke with different colors.

Cheers,

Michael

Hi Michael.

Thanks for the feedback and thank you for the example scene. I'm looking  doing some coloured smoke tests.

 

Cheers

Hi sklauss.

 

Thanks for your positive feedback, much appreciated.

 

I have just uploaded a couple more vids:
