Great video. I wanted to make the sun using shader programming for fun, and now I decided to watch how it can be created with houdini to have some ideas and inspiration.
Thank you so much for providing this tutorial. I've also subscribed. I have a couple of questions. Does each voxel represent a charged particle? What does 4.443342 represent?
No a voxel has nothing to do with charged particles as this can not be replicated by any computer available at the moment. Voxels are volumetric pixels and store depth information, nothing else. What value do you refer 4.43342 to? Throwing random numbers makes you look like a lottery drawing. Thanks
@@IDAVFX They are talking about the point wrangle at 44:33 where you have random(@ptnum * 4.443342); it's just a seed for the random() function. VEX random() takes floats, but it only varies the random effect for integer changes, hence the seed.
Awesome tutorial. Just ran through it. Got a question. I'm getting bright flashes when I hook the sphere points into the magnetic field. Happens over a frame and then fades over a couple of frames. Any idea of what could be causing that? I'm wondering if I screwed up a step haha.
Thanks for good tutorial! And I have a question. I can't understand Stick_to_surface POP VOP. Why did you use negate? It's hard to understand 'volume gradientfile'.

Thanks for the nice comment - Glad you like it
Dope!
Definitely

Send me your scene file and I fix it
@@IDAVFX I'm afraid the same thing is happening to me, trying to work it out now; is there a quick answer? Great tutorial btw

Thanks a lot, appreciated.

Those are attributes from the asset to make the points stick to the surface and make the sun bursts ... Thanks for asking
