Thank you!

Thanks Nitin for the thoughtful comment and liking this piece. Really appreciate it.

Thank you! :-)

Thank you!

Bappa!! Thank you :-)

Thank you Zebu :-)

Thank you. Wish you good luck too!

Thank you!

I have updated the video description with the link to the scene file I shared on the "Bifrost Addicts" discord server. Please let me know if you have issues joining.

The quill was just another strand and you use the extrude tube compound to create actual geometry.

The Bifrost team is working on all of that, Bifrost is pretty new compared to Houdini, you can't expect it to be as powerful from the beginning.

@@leecaste Agreed, I really wish they have thing like wrangler node, and provide getter and setter functions to attributes, have utility functions to do things like raycasting, querying neighbor points, find closest distance, matrix and quat calculation, have code that can simply add a geometry element, add and strip attributes. One downside of Houdini is non-unified coding style, I believe Maya can do better on that because it does not have to consider backward compatibility.

Yes, that's certainly one advantage that bifrost would have since its more current generation and won't have legacy stuff to support. Some of us did bring up a VEX like JIT compiled coding environment for bifrost. I guess first the entire platform will be stabilized and all the core functionality made available via the visual programming front end and when that matures a bit, we might see some movement on coding support. There's no doubt in my mind that all that would eventually happen so its just a matter of time and enough dev resources.

Well, that’s the whole point of sharing the scene file with the users to help them learn this. I don’t see what your point is?

@@noizfactory He thinks bifrost is too hard for him to use, so it must be for others as well. LOL

Currently Bifrost doesn’t have direct support for other renderers besides Arnold. Hopefully that’ll change sometime soon once there’s a public SDK. In the meantime, one way to render it in another renderer would be to export this as alembic from Bifrost. And yes, this is all Bifrost strands i.e. curves.

I think that should be totally possible and did cross my mind when starting on this. On my to do list so hopefully will get to it at some point. Thanks for watching the video! :-)

@@noizfactory Yeah, would be cool to not need to use other programs to create procedural trees, maybe they'll also add the ability to create procedural terrain.

Yes, its a prototype so hoping to continue building on top of this. Barbules on barbs added as well. Link updated in the description.

@@noizfactory cool! Do you an expert in bifrost? I have a few questions)

@@CGMeneldil Not an expert but ask away! :-)

Dive in! Its a lot of fun!

Thanks Pranay! Scene file link added to the description :-)

@@noizfactory awesome, thanks. Your file will help me dig deep into strands. I'll be exploring Bifrost more deeply during my Christmas break.

In my case, I simply create an up vector array with Y up (0, 1, 0) as the vector. Then I pass this as the rotation axis to the rotate points node and for the amount of rotation I pass 180 degrees of rotation through a degrees_to_radians node. This orients my crowd instances to face inwards towards the center of the stadium.

For learning Bifrost itself, please check out the new official central hubby Autodesk for all things Bifrost: makeanything.autodesk.com/bifrost Here you should be able to find lots of links shared by them for learning Bifrost. Re this specific example, I’ll try to post a tutorial sometime to explain my process. Thank you for checking my work 🙂

It doesn’t do that out of the box yet. Hopefully we will see some rigid solver in Bifrost at some point!

definitely something we want to do!

@@noizfactory I hope you guys get around to it soon. I see a lot of great stuff being done with bifrost. Rigid Destruction capabilities would be a great addition

Right now you cannot round trip the strands data back into Maya as curves. You will have to go through the alembic route. If you want to attach them to xgen or yeti as guides, then afaik, both accept guides alembic file as well (at least xgen does) and in production I’ve always eventually baked out the guides as alembic and attached them through the guides modifier for final rendering.

Hello there, Yes, currently you can indirectly convert those erosion lines into Maya curves by exporting the bifrost strands as alembic and then importing that alembic into Maya. You could also directly render the strands out of bifrost with arnold as they are treated as arnold curves. I do plan to share this scene with the community at some point. I still need to clean up the graph, add some more features and test it a bit more. I can't promise how soon that will be. In the mean time if you have any specific problem that you need help with, then please feel free to start a thread in the bifrost forums or ping me. Cheers, Sachin

@@noizfactory Thank you for the quick reply. I am looking forward to see your scene file when you are ready. Could you please direct me to the bifrost forum of your visit so that I could meet you there or post any threads. I am a newbie in this topic. Don't know where the community usually hangs around. If you can lead me there it'll be greatly appreciated. BTW, could you share your email for further communication?

@@aladdinabudula8193 This is the official bifrost forum on Autodesk Area: forums.autodesk.com/t5/bifrost-forum/bd-p/6060 And this is the unofficial slack group for quick chats and discussions with bifrost users (note that is not endorsed or supported by Autodesk in any official capacity): join.slack.com/t/bifrostaddicts/shared_invite/zt-jqm1ues2-HGAOsCwULMbpj8c3OQtAKg

Thank you for checking out the video and for your kind comment. Yes, the eventual goal is to be able to generate procedural worlds within Maya. There are still some key pieces to the puzzle that are missing in bifrost right now but its only a matter of time before they are resolved. In the meantime, these kind of experiments help us push the toolset and use it in some out of the box ways :-) Cheers,

Hi Marc, Apologies for the delayed reply. The latest Maya 2020.4 release which comes with Bifrost 2.2.0.0 introduces voxel fields so you can check out the latest release! Sorry, wasn't able to really talk about it until the official release :-) Cheers, Sachin

Thank you :-)

Thanks Pranay!

Hi, sorry for the late reply. You can check many official and unofficial resources available online for learning bifrost. A good place to start is with Paul Smith's videos on his Vimeo channel: vimeo.com/pooby Also, check the official youtube channel of Autodesk, there's a few bifrost lessons there as well.
