[@comicbstudios]

@@CBaileyFilm Fun fact, the technical term for that is 'the bulge'.

[@charleshoran9962]

The best part of your demos/tutorials is that you go past 'what" and into 'why'. Personally I find the 'why' much more important. Thanks for outstanding effort.

[@themalcore_]

As a blender beginner, I would say a wider-shot of the whole node network would be really handy as It can become hard to follow, but what a phenomenal tutorial! Couldn't believe how good my final result came out. Thanks a bunch

[@drumandbassnz4678]

yeah agreed, was really hard to follow what was going on also it seemed like he was cutting between where the node setup was changing

Amazing result but can you please zoom out more and show the whole node tree sometimes, it's really hard to follow at certain points.

[@rift7573]

@Maxwell Brayden what does this have to do with anything EDIT 1 second after this was made: no offense to flixzone

[@hungryconfidence1562]

For real

[@dakotaridge]

Only one complaint ... the 14,000 times in the video where after an edit, 500 settings were changed and not a word was mentioned about it. Beyond that, what I appreciate most is the presentation. You're very well suited for making these kinds of videos. Some people have the right charisma for it and others don't. You're at the head of the class in that department. As far as technical content, the final result is the best I've seen yet. 6 stars out of 5!

[@CBaileyFilm]

Thanks so much Dr. for your kind words. I get about 5 comments a day on this video about the bits I accidentally cut out. It's been over year now. I've been very careful with my edits ever since. lol

[@toa5tytunes]

You're pacing and tangents of blender knowledge are amazing!

[@mrhoward5075]

If you are having trouble getting the same color that he is at 25:02 and are getting a regular white instead, he replaced the multiply node at the end of that section with a Vector Math node that is set to multiply off-screen.

[@janos71]

For the mixing of the texture with the vector (9:16) I like to put the RGB output through a vector math node, subtract 0.5 from every value and then use "add" in the mixRGB node. This way the distortion happened evenly and not biassed to direction. probably doesn't matter in this example though.

[@MONGIE30]

Managed to do it eventually. Got a bit confusing as you started to get a lot of nodes and i ended up plugging one into the wrong place, but it still amazes me what can be done in Blender. great tutorial!

[@charlesweaver3000]

Thanks for the great tutorial! At 0:52 you mentioned that the dropdown menu disappears if you click away. Pro tip: you can press f9 on your keyboard to get it back.

[@FelinaFaerlaingal]

The cuts and the constant switch between very zoomed parts of the node tree make it very difficult to follow The fact that you keep changing "let's do this... or not, wait this would look better... no back to this." also add make it hard to follow you You explains why you use some nodes very well, but the rest of the tutorial is a bit of a patchwork, which is a shame because the end result is amazing Maybe if you could post a screenshot of the final node tree somewhere, because even a couple watch later, I'm still not sure I got everything plugged where it should, and I get nothing close to your own final result

[@Demorthus]

I'm very much a newbie working on getting more into Blender, but I did want to say I love tutorials like this where you're also able to learn alot of useful shortcut keys. That said, I'll probably see about posting a link here with the whole node system, hopefully less people will have to go back & forth during the video hehe.

[@denisguay4315]

Just stumble on your tutorial and wow its amazing, i found what i was looking for and i like your explanation while doing the work and i like you are taking your time with too. Thanks

[@mojoober]

The trick you use at 22:03 is a good idea, but if you use the Node Wrangler plugin (included in Blender, just enable it in settings), you can just Shift+Ctrl+Click on any node to isolate it like you did here. For nodes with multiple outputs, just keep Shit+Ctrl+Clicking on it to cycle through the outputs.

[@kronos548]

really good end result, going try to adapt this node setup to create a milky way type effect

[@lolman5997]

Hey! Your content is always great and easy to understand. Keep it up!

[@CBaileyFilm]

Thanks so much lol man!

[@thefreshest2379]

On the mix node mixing noise to the vectors, you should set it to linear light. When you mix in noise it moves vectors on average 0.5, the linear light operation fixes the problem. It didn't matter in this project but it might in the future.

[@wareagle9655]

All of you guy/gals that do these tutorials are just amazing, not only in your knowledge of Blender but of what you want to do and on an almost daily basis. Just curious are most or some of you doing blender for a living and that's why you're all so good? I've been trying to learn it for over a year but I have so little time to use it that I can't remember how I've created things in the past. -The Workaholic.

[@Cantersoft]

12:35 When I switch to Alpha Hashed, everything becomes transparent except the bright spot in the middle and the texture seems to stop working. Any idea how to fix this?

[@edenseeker]

You would benefit yourself so much by using node wrangler, not just for speed, also for isolation each texture for testing (shift-click on node).. Also nice tut, thanks!

[@Schmambo]

This was a great tutorial, that was far visually pleasing going through the entire process! My only criticism is that it was extremely chaotic to follow along because of the abrupt transitions with quite a few changes made without explanation. That being said, it's making me learn what was changed, so can't fault that. I just wanted to make the same thing X'D Thank you for this nonetheless, I made a galaxy!

[@rajmistry3141]

i cant get the colors going from the coloramp . no matter how much i cange the color the galaxy colors remains white . any suggestions?

[@CBaileyFilm]

Are you piping the colour ramp into a math node? I do it for the emission, but I keep it black and white - if you want to have colours in your ramp node and still use a math operation on them to increase the glow then use the Vector math Node. The math node only works with single floating point numbers, whereas the vector math node can do math on sets of 3 numbers (colors have Red, Green and Blue values in them). Just make a vector math node, set it to multiply and enter the value you want to multiply by into the 3 fields of the node. Or you can make a value node, enter the number you want to multiply with once and plug that into the bottom socket of the vector math node. Hope that helps!

[@rajmistry3141]

The Emission Strenght is not appearing on principled BSDF I did it by: Color Ramp and Value to a MixRGB (Multiply) And then connected with emission.

[@dreamthoughtplays]

Thanks for this tip.

[@StevenCookFX]

CBailyFilm: If you create a new object and the option dialog that appears so you can set things like segments disappears cause you click on something else or an empty space you can always bring it back with F9. If you do any operations or other stuff its gone and will not come back. Just an FYI. :)

Our universe is nothing more than a collection of nodes.

The swirl isn't working for me. The texture stays uniform instead of stretching when I rotate the center nodepoints. Any idea how to fix this? UPDATE: I forgot the texture coordinate node.

AAaaaannnnndddd now I'm a subscriber, tnx for the great video.

[@CBaileyFilm]

Aaaaaaaannnnddd THANK YOU! :-)

[@mr.merriment]

The point light doesn't work correctly for me and always just shines toward the view. Doesn't matter from which side I look at it, it stays completely black behind the light source. How can I solve this? You should also show when you change some of your nodes. There is always a cut and suddenly you have completely different nodes with different settings. This makes it hard to follow.

[@Sedryn_]

Tip: F9 makes the menu reappear.

[@maxmccoy9761]

Not to be a stickler, but since we are looking at galaxies from the outside, technically there shouldn't be stars in the background, as stars do not exist outside of galaxies. I guess the stars could be seen as really far-off galaxies. I think a good solution would be to randomize the galaxy colors with an object info node then add a particle system with the galaxies as the source. Despite the discrepancy, art if often about how something looks, not how realistic it is, so keep the stars if you feel like it. Or if you like to tick off astronomers.

[@coronaphone710]

But practically every galaxy has a dense black hole which emits all sorts of light and could be observed and mistaken from that (hypothetical) viewpoint, for a star.

I take the exact values as You do while stop and go several times through Your Videos.

I’m trying to rotate to distort it but it just keeps on rotating the whole thing, I haven’t selected the whole thing. I managed to do it a couple of times but don’t know how I got it to work? Sorry I’m a noob.

[@FutureWithinReach]

Happened to me, however I fixed it. Look carefully you might have selected vertices, check if you see the orange glowing color on one of them. Diselect them, and rotate and scale it with middle mouse button. I had one vertices selected on the brim of the circle.

Amazing. It should be possible to Twist that noise without messing with the UVMap, however it might require some tedious math work with nodes. I wish one could just enter a function or formula via python.
