[@DocTwoEight]

From the first minute of the tutorial when I saw those light bounces this became hypothetical to me

[@IrreversibleExtents]

You have no clue how long I have waited for this tutorial, as I am not very happy with the **other** black hole shaders out there. YOU ARE MY SAVING GRACE

[@samk9632]

Subtle, but important things you might miss: 1. Make sure you change the color of the refraction to be 1, not the 0.906 value that blender has as default. 2. 0:40 have high light bounces reply to this with anything else you notice people might miss

[@rogerspence1332]

Honestly I don't know how it happened for me, but when my multiply nodes were added they all had clamp on automatically. For anyone that's getting weird checkboards after the grouping this is why

[@xuecunfan5432]

Hi, how do you know the divide node in refraction should be 243? how to get it? (11:54)

[@The_NSeven]

@@xuecunfan5432 Yeah it seems like a very arbitrary value

the layered up refrection....whoever came up with this is a genius

[@SOMNAMBULA-z5q]

Dude, you are genius! Finally CORRECT black hole

[@samk9632]

**almost** correct. Black holes often spin and that distorts things in an interesting way. I haven't figured out how to achieve that, but when I do, I'll upload it as a "bonus" tutorial

[@samk9632]

@@IrreversibleExtents spinny effects coming soon don't you worry

[@cybercontour1305]

This BH shader relies completely on your light path bounces setting, specifically less than the 256 setting in the video. Change that setting to max [1024], and your BH becomes an anti-BH. Kinda interesting.

[@astrofabric8924]

sam you are an actual genius

[@Ntropic]

Thank you for the great video. I wanted to point out, that the black hole you are creating here is more akin to a non rotating black hole, wheras the interstellar black hole is a rotating Kerr black hole, which looks a bit different on the sides.

[@frostypotatoking]

"Play around till you're happy with it" My laptop did not like that

[@Moai_Guy2001]

Great tutorial, Had to download blender 2.93 for this but its working great and thanks for the tutorial. This should really be the go to tutorial for black holes, appreciate it

[@SEZMALOIN]

The array modifier scales out the sphere for me

Amazing. I'm trying to make this projetc right now

[@StanSpk7]

Might've already been 7 months since your comment but thanks, I just started out learning blender recently and decided this will be a fun project but goddamn he's using so many shortcuts and doesn't explain anything - I was stuck on that part for like 20 minutes until I found your comment. Thanks again

[@jmm1233]

going to make a black hole out of the default cube because why not

[@TheSpacePlaceYT]

It would be amazing if you had the source file available. EDIT: Just ask for it here and I'll send you the source file I created. I followed the tutorial exactly, so there's no variation between the end of this video and my version.

[@RSpracticalshooting]

this is a year late but do you still have that file?

[@TheSpacePlaceYT]

@@RSpracticalshooting Yeah I might need to find it though so I'll get it to you tmrw or something

[@hotgates9324]

If the IOR doesn't behave as it should, like all you see is a faint refraction and not the black whole effect, don't worry it will be fixed once you plug the Power node into the color input of the Refraction BSDF node. Don't know why this happens. Using a GTX 1080 Ti with blender 3+.

Still it's not wortking :/ I need help with that

[@Theoriginaldrog]

For anyone setting the IOR to 1.001 and not getting anything, try setting the total light bounces to 256 or a high number.

Hi，i set light bounces to 512 and reflect still not work, the blackhole still rong

12:07 what to do if the lower circle (small) is very low and the upper arc is not so curved upwards

[@rhashadcarter2051]

You clicked on of the node and it just automatically linked to something that was off screen. For future tutorials you should specify what that is and what its attaching to becasue it cn make or break a material set up. I had to rewind and just figure out hat you did to follow along.

[@Seed93]

Did you happen to figure out what he did there and how to do it? EDIT: I think he is using ctrl+shift+click to automatically connect to a viewer node with the node wrangler addon

[@samk9632]

correct

[@menemeyd-destroyer243]

How can you connect it in Blender 3.1 ? I cant find any shortcuts

[@Me-te8xq]

@@menemeyd-destroyer243 Just press ctrl-shift and left click on the node you want to do towards to. Remember to enable node wrangle add-on in the add-on area of the blender preferences.

[@GnuSnu]

cool

[@crehenge2386]

you're using the node wrangler?

[@user_3eg8cp1a2d9t.]

Do you know how to achieve this 'center ball/Lensing' material using Arnold？ because I tried two different methods, one just plugging the facing data into IOR and not copying the center sphere, and I got a similar result, but the width of the ring becomes very narrow where the left and right sides of the ring begin to "bend" upward. The second method is copying the same logic of this video but not working

[@samk9632]

refraction should work along the same formulas in both render engines

[@user_3eg8cp1a2d9t.]

[@freddiejiang7883]

@@samk9632 Hey Samuel is that possible to transfer the blender nodes into Arnold to achieve similar result. The other Arnold tut doesn't get better result than this!

[@N0T_Dem0n]

how did u make that a sphere

[@ReaZaaa]

alt+shift+S, but I think you already figured it out^^

[@ColonialPuppet]

at around the 4min mark, how did you extrude the circle before scaling it? the normal ALT-E extruding didn't replicate what you did, and scaling it doesn't include a face as a result.

[@ColonialPuppet]

never mind, I'm an idiot. You hit E and then S lol.

[@steveblack720]

I can't. I completely copied his settings, his nodes, his meshes and I still can't get same result. I don't understand anything out of it and how this works... I'm just lost

[@steveblack720]

and what amazes me more is the fact that he somehow managed to improve the lensing even more using a ton of nodes
