I watch and am amazed every time, I love the background of the craftsmanship, it seems like everything is incredibly easy but I realise how it really is... RESPECT
It's really cool to make particles using cel gen! Absolutely genius! The simulation of the simulation 😄👍 Thank you, Simon! You inspire us to recall and apply some rarely used things like Membrane! Thanks again
Saturday morning coffee and your tutorial.... great way to start any day. :-) I Really like it. Thank you very much. And using the cellular generator instead of a particle generator is also very nice as I was assuming (wrongly) that is was a particle generator watching the intro. And the compound blur... and the... and the.... all so very use-full.
Simon, I'm pretty sure that the solid black is needed in the background, for the composite, because there has to be an actual number to work the layers against... or I should say an actual RGB value to work against... If I'm correct the Alpha channel isn't actually a numerical value, but the lack of a numerical value... think of it this way... the transparent values are transparent because they do not have an RGB existence to work against... where Black is an actual value to compute against... if that makes sense...
Yes, you are right - in part though it's not quite true what you say about the alpha channel which does have numerical values that range between one for fully opaque to zero for fully transparent. All a bit more than I wanted to have to try and explain in this tutorial. It's a topic I have covered extensively elsewhere going deep into the maths of it.
@@SimonUbsdell What I was thinking about mostly is that the number used has to be an RGB value rather than an alpha value... calculating RGB to RGB, rather than RGB to Alpha... computer thinking... I've run across the problem before with some of the backgrounds I use on the videos of my channel... the simplest fix of putting a solid in the background... is the one that I used too, but I didn't think of it as a math calculation... which, when you think about it is everything an image is made from... but in this case which values apply to which values...
You might find this tutorial useful as a beginner's guide to this question: ruclips.net/video/gbiOfLjz6k0/видео.html There is of course loads more to be said on this subject. An Alpha channel is literally no different from an RGB channel in that they are all simply sets of pixel values and alpha is not some secret magic. Where it gets complicated is in how the alpha channel is leveraged within the composite and I hope the above tutorial starts to explain some of that.

I love the level of enthusiasm you showed during this one. Inspiring. Thank you.
Simon! I am very happy for this lesson! I enjoyed this a lot and everything worked perfectly. Thank you so much!!!

Thank you but you are much too kind!

Wow! Yum just getting into Motion and your tutorials are unlike any others out there - thank you so much!
Amazing! Another truly interesting and inspirational tutorial. Many thanks Simon.

Wow! This is a good one. Thanks Simon!
very cool effect!
Love it, Thanks Simon!
Man! You’re a procedural fx powerhouse these days! So so effective 👍
Gosh, thank you!
wonderful tutorial
Every time I watch your videos makes me rethink the possibilites of apple motion! Brilliant as always
That caustics trick alone is beautiful. I might repurpose an older iMac into a glorified lava lamp with that!
Love this one. Thanks Simon.
That is very cool!

I’m shocked you’re good at motion 👍
hmmm… sci-fi things.. cool!
