▬▬▬▬▬▬▬▬▬
Take a look at my tutorial on how to simulate a solar system inside Unreal Engine. This tutorial can work in Unreal Engine 4 or 5. It's a very good way to get a grip on Blueprints within the engine so a beginner and intermediate user can achieve this.

[@Notlies673-df1lt]

Love it, this tutorial will help a lot with a game I’m planning to make

[@ArghanionsPuzzlebox]

Glad you enjoyed it

[@FluridCube]

Great Video! As someone familiar with using nodes in blender and programming in general, this was a great way to learn the basics of the Unreal Event Graph! It also helped i wanted to model out some fake solar systems :)

[@ArghanionsPuzzlebox]

Glad it helped

[@yoneyone5173]

great video, you can make a video on how to create a landable planet

[@neveridel]

Hello! I've got a question: how can I make this solar system scene interactive? As an example: I want to have a stationary first person character who is able to pause the game, rotate/zoom/pan the solar system, click on the planet and open the menu widget. Thanks for the great video!

[@ArghanionsPuzzlebox]

Hi. I've sort of done and made the implementation for this project found here: kzbin.info/www/bejne/mGLbcpuwbdtphbs I haven't made a tutorial for the whole menu part, but this particular project does have menu functionality with options and ability to load maps etc. Let me know if that is of any help.

[@neveridel]

@@ArghanionsPuzzlebox much appreciated!

[@shakaama]

would it be too crazy (without having AAA gaming computers) to make the solar system true to size?

[@ArghanionsPuzzlebox]

There are quite a few limitations in unreal engine but there are other game engines that have done something similar. Check space engine.

[@emiliojrodriguez6522]

I am interested in creating the relative movement of planets, moons etc...

[@Thorrwulf]

Awesome, works perfectly!

[@tevx9670]

nice one thanks

[@enriquehirshfeltikov2395]

If, say I was to use actual mathematical values for say mass/gravity and a random of say orbital plane etc. Do you think this could be used as say a procedurally generated star system with anything from a single star, binary star, or the rare trinary star system?

[@ArghanionsPuzzlebox]

Yeah. Potentially. But as to how you would get all of that done I still don't know. I'm trying to sort out custom gravity right now but so far I haven't been successful.

[@enriquehirshfeltikov2395]

@@ArghanionsPuzzlebox well I know that you can specify gravity in UE the argument of gravitation constants.... I'ma have to play with that, but was looking for a foothold.

[@jakesgoryadventure]

One thing I am wondering is if UE5 could derive gravity on day, your simulated earth using the mass of the planet, your distance from its core, the mass of the sun, and the distance from the sun. Can you get it to set up a realistic orbit by giving it the mathematical values?

[@UltimediaProductionsPH]

Great stuff as usual!

[@_pastras]

Are you using a point light to cast light in all directions?

[@ArghanionsPuzzlebox]

I actually just used the emissive of the star. But a point light can work. If you want rays, you can use a directional light with some clever camera positioning.

[@EkkiKakinaki]

I really like the theme of your lessons. Tell me how to make the planet spin on its axis. Thank you!

[@ArghanionsPuzzlebox]

Normally I just add a planner in the material to fake rotation. But if you want the actual mesh to rotate, just use a simple rotator inside a blueprint with the mesh as the target. It will make it rotate around its own pivot.

[@NightVisionOfficial]

Can you do a video on how to make the sun and the moon using the light? It's for the sky.

[@ArghanionsPuzzlebox]

Seen from the planet surface?

[@NightVisionOfficial]

@@ArghanionsPuzzlebox yes, i haven't found it yet. I would like to have the moon like there's the sun when you have the light

[@ErrRationale]

Great channel, I'm certainly keeping locked on your progress and videos. You've helped me solve an issue I was having before in another video! I was wondering if you've had any experience with the MaxQ Spaceflight toolkit for UE?

[@ArghanionsPuzzlebox]

Glad to help. I have it but not used it at all. We do have someone on the Discord Server that was heavily working with a similar setup like this toolkit.

[@shakaama]

Hi, I think I messed up, setting up the project. is it just an empty project? you can't set it a 3rd person or 1st person?

[@ArghanionsPuzzlebox]

I've used a blank project but any template should work.

[@pickard1988]

Hi, I'm new to UE, at any point do you show us how to set up the lighting for this scene? like making the sun a light source while still being able to see in the scene for example, I can't seem to find something like this

[@ArghanionsPuzzlebox]

Hi. Glad you decided to try Unreal. For this particular scene, the Directional Light is used to fake light emitting from the Sun as at such a scale, the scene would not be lit from the emission of the Sun Object itself.

[@a.s.b.]

would it be hard to make a solar system completely procedurally generate using this? (obviously modified a bit, but hopefully not that much)

[@ArghanionsPuzzlebox]

Quite a lot of work is involved but yeah, it's possible. Joint the discord server as there are some people currently talking about it

[@_pastras]

Tell me about that star shader? Looks fantastic

[@ArghanionsPuzzlebox]

Here is a lengthy tutorial on how to make it kzbin.info/www/bejne/oauqe2h8g8p0ebM

[@faradaysinfinity]

Amazing!!!!

[@ArghanionsPuzzlebox]

Thank you

[@peter486]

welldone man

[@ArghanionsPuzzlebox]

Thank you

[@itsameamiaaa]

Question! I tried making a moon orbit a planet but it sort of has a slighshot more oval path than a circular same distance all around path. How do you fix that?

[@ArghanionsPuzzlebox]

This has happened using my settings? only thing I can think about is that the meshes aren't positioned in the center properly or that their origin points are offset.

[@itsameamiaaa]

@@ArghanionsPuzzlebox that was it! I figured it out a day later but yeah the mesh wasn't centered

[@jstara9125]

@@itsameamiaaa Do you mind explaining how you resolved it as i have the same issue. I tried changing the Static Mesh to another sphere and I tried centering the Mesh Pivot point however both fail to resolve it

[@itsameamiaaa]

@jstar a its sort of about putting something in the center, its been a while so i dont remember but there is an icon or some sort of controller that you need to move so it is in the right place

[@Anm8or]

I am having this issue as well. I am not able to locate the setting that will center the static mesh. does anybody have the solution for this slingshot type issue?

[@giancarlomartinez5630]

Wow!!!

[@RSProduxx]

doesn´t move at all... paused step by step and made sure all connections are correct... i have 2 spheres in that scene, 1 as parent for the BP, the other ist just there... nothing moves when I press play...

[@ArghanionsPuzzlebox]

Hi. I'm 100% sure this works if the setup is done right, I am not sure what could be wrong in yours but feel free to join Discord and we can look over it there.

[@RSProduxx]

@@ArghanionsPuzzlebox mh okay, I might actually :)
