Create Realistic Black Holes in Blender | Full Tutorial

[@AlaskanFX]

Hey everyone! I just wanted to make sure to again note the fact that I am by no means the creator of the shell method of lensing. The accretion disk is fully my own work but the lensing setup has been around for years and was developed by an absolute genius on (@samk9632) Samuel Krug's discord server who wished to remain anonymous and even before them the conical shells method was used by Nika Maisuradze (www.artstation.com/blackrainbow). My contribution to the lensing was only the geometry nodes scaling ratio trick to improve render times and the simple halo amplification. Never will I nor do I want to ever take credit for the work of others so I figured I should make the credit very clear in this comment. EDIT: Just a small thing I've discovered in the last few days but if you want to get a better "halo" effect from the gravity lens then you can delete the last power node (the one right after the add node) and set the power node before it to 1.57 instead of 1.74). Its a small thing but it improves the light amplification halo around the event horizon a bit so I figured I'd share. With that, I hope y'all enjoy this tutorial and have some fun with this!

[@darshjoshi1641]

You may not take credit for lensing effect, but everything else! Great tutorial man... The final output is so beautiful. Thanks and keep 'em coming.

18:24 When Im in the accretion disc and put the values you put in the map range node the accretion disc is not white but a dark gray color and the rest of the accretion disc is a light gray. Pls Idk how to resolve this.

I'm genuinely blown away by how closely it resembles the Interstellar Black Hole, it's almost on par with the Samuel Krug one. In fact, this might end up being the go-to blender tutorial for Black Holes.

[@AlaskanFX]

Thank you so much!

[@TheSpacePlaceYT]

I agree. Even though I use SpaceEngine which is so much easier to use, it is still wild we can even get black holes with this level of detail. The only issue with SE is that it is licensed to where you have to credit them, so making your own black hole may benefit since you wont have to credit the company*. *Spelling error.

[@SiderealRotation]

Now all we need is the kerr newman black hole model.

[@gasmaskghost4110]

For those wondering the Musgrave Texture node was replaced with the Noise Texture Node, and if you want it to work the same as the old one then subtract by -1 the Detail factor (Although not necessary). Also the Dimensions input was changed into Roughness and works a tad differently so just put in 0.92 in there which is the rough equivalent of 0.12 . Also Also if you aren't getting those cloudy looks then mess with the Distortion, it basically controls the dark spots in the map.

[@SpaceAce11VR]

for the .04, you can do the math (its roughly 0.97265), as it says on the blender 4.1 manual

[@SpaceAce11VR]

and 0.757858 for .05

7:50 In case anyone is doing this tutorial but doesn't want to download Node Groups, I was able to find an approach that has similar effects. 1) Unwrap your disc. I in particular used Orthographic view from above, and Unwrapped from View (Bounds). 2) On the material, have a Texture Coordinate set to UV, connecting into a Mapping Node. 3) Set X and Y Location to -0.5m on the Mapping Node. 4) Connect the Mapping Node to two Gradient Textures, one set to *Radial,* another set to *Quadratic Sphere.* 5) Have each Gradient Node connect to a Checker Texture. 6) Have both Checker Textures connect to one Math Node, set to Compare. 7) Connect the Compare to the Material Output. Done. Now you can tweak the scale on the Checker Texture's to control the shape of your radial Checkers material. The one connected to Quadratic controls the size and spacing of the 'Rings', while Radial controls the size and spacing of the 'Stripes'. Final product should look like this: [Gradient Texture] ---- [Checker Texture] [Texture Coordinate] ---- [Mapping] < > [Math (Compare)] ---- [Material Output] [Gradient Texture] ---- [Checker Texture]

Setting up the shader nodes was challenging, but finally got it set up correctly! I used the Gumroad file as a guide since I kept missing steps in the tutorial. If it's not working for anyone, double-check the shader nodes. It's easy to overlook a missed connection or an incorrect connection.

Hello, I've got a problem in the "adding the halo" area where when you plugged that group into the colour node to get that affect, it turned the sphere gray for me, why is that? keep in mind, the halo ring did work it's just that the sphere turned gray. Everything else was working just fine with me prior to this. Edit: after trying to change the values a bit, "to min" is the problem, when I set it below 1.7, it stays black and produces a really faint halo ring, anything above 1.7 turns it grayer and grayer and 2 turns it to completely dark gray, going anymore above that and it keeps turning whiter, at 2.5, it's almost completely glowing white. Edit 2: I've reached the accretion disc area and I did as you did but then, at exactly 18:35, the accretion disc was gray for me but I realized I was in Edit mode, jumping back to Object mode but it black but not invisible. With you, it's like it's invisible but for me, it appears completely black but not invisible so it still blocks the black hole from the sides. Edit 3 (FIXED): I accidently plugged the Emission node to Surface on "Material Output" instead of Volume. I restarted the whole project and REALLY messed up the scales and when I got back to the accretion disc, I got other problems EVEN AFTER plugging it into the Volume. So make sure y'all that you pay attention to the scales of the objects.

"render out a quick pass in HD" -render takes 71 hours *what did I do wrong*?

[@maikelloitmets9504]

I was, exited to do this but half way thru I realised that mine doesn't look like yours and i redid my steps and cant find problem.

[@antonisx5916]

Please how can I export it with the color and everything? When I export it it spawns without the texture, it’s just a ball and the line

[@twistcrocodileanmations]

Why aren't I getting the halo effect on it,did I do something wrong???

[@AKS3D]

Change tha multiply values

[@RlVlN]

14:59 For the halo ring part when I added the map result into the color slot my whole sphere went black but it looks like changing linear to smooth stepped gave me the same result in the video. In case anyone has a similar problem

[@skyline3d]

First of all thanks a LOT for this tutorial because I really wanted to make a black hole, but as a 3week old blender baby at 21:01 you totally lost me, could you explain which nodes did you group together? I tried to group the last 5 notes you created for the thickness, but then it doesn't show like yours. edit : I found the solution: Select the value node: press CTRL + G, I'll let me comment for anyone else having this problem

[@AlaskanFX]

Yup, ctrl + G, glad you like the video!

[@Dany_453]

@@AlaskanFX I got lost when you started the accretion disk, because when I add the min and max values in the map range it doesn't appear like yours

[@Auricstarlight]

the lens doesnt seem to be showing up in the render? possible fix?

[@InFGG]

bruh i did thin in blender 4.0 and the last stage to making it realistic (Adding emmision) 18:50 didnt work at all it looks, fine? but the ring isnt actually emmisive i think i fucked up something along the way lol edit: i just realised i had to gide the circle lol btw still looks pretty bad

[@swxvex]

whats your discord?

[@nikj1178]

The only way this tutorial could have been better was if your keystrokes were displayed throughout the entire video, maybe an external program or something. Thank you for the video, not only was it a great tutorial on black holes, but also the entirety of blender.

[@CATHARSIS69]

Have someone problems wuth cube "accretion disk" ? I'm doing everuthing like in tutorial but I can't have that result. If somebody know why it's happening please text here

[@hppn5]

Hello! Did you put emission shader into volume? If you put it in surface, then black cube appears in the middle of the black hole

[@coober28]

when i am rendering the image, the checkers texture comes back, please someone help me fix this

[@rabiatul_emma]

I done everything but when I reach at the end of the tutorial the halo light kind of got swallow. So can anyone tell me what did i do wrong

[@akshitjoshi7440]

Can you make the animation of neutron star in blender

[@iam_knight_guy]

I can't get perfect halo effect in sphere

[@JesusRuiz-un6uq]

Hello, how did you achieve the effect at the beginning that the black ear ring was moving?

[@matteo_petruz1435]

at 18:40 my inside is white and not black like in the video. How i can fix it?

[@LoafiRadio]

When I tried to render the animation/image, it kept coming up with 'error no render output node in scene' someone help me :(

[@RavenCypher676]

when i go to render the checker pattern appears how can i fix this

[@whitedevil1884]

i cant figure how you did the halo ring can you show it in a more better way :)

[@flision99]

please help my volume isn't working properly it isn't creating the round white circle the float curve isn't really doing anything

[@guidenstuff]

Hey, so i followed your tuturiol exactly up to the point of starting the refraction when i encountered a weird issue, when i delete the bsdf shader off the shell instead of all the layers going black, the outer most sphere still has a material. At first i tried resolving the issue by disconnecting the group input from the set material node and configuring the material manually in the set material node. It worked at first, turning all the shells black, but then the IOR settings just didnt do anything. I tried messing with other settings but nothing seemed to work. Its a very weird issue and i have no idea what causes it. Idk if others have had this issue but if there is a fix i would love to know, Thanks

[@kiratpreetsingh4107]

hey did you find the fix

[@SeaHorseOo]

The hawking pole jets are cruely missing from these simulations... Oo ... Just boolean two cones at poles. Right before the geometry node, plug and play... 🤨!

[@Derpduck.]

I do not understand it to this day, but I am amazed by the resaults!
