Introduction to Dynamic Mesh and Geometry Script in Unreal Engine

Project Files: / 95136582 .
Today we are going to look into the basics of Dynamic Mesh component and Geometry Script plugin. Here we will see how to generate a mesh in runtime using UDynamicMesh component and do some basic operations such as
- How to select a subset of vertices from generation mesh
- deforming it with a Perlin noise
- apply tessellation
This would be a preliminary research for integrating dynamic mesh for the infinite landscape system we have worked on.

"GeneratedDynamicMeshActor is currently Editor-Only" ... so while it works at runtime in the editor, it does not work when producing a build from this right?

[@WsEKond]

This is save for the world generation, or not?😮 You are the best! Thanks for your dayly tutorials!

[@CodeLikeMe]

i'm gonna try to integrate this to world generation

[@aprivatechannel1152]

Hello! I already tried to implement DynamicMeshComponent into my terrain generation, and I found it to be actually slightly slower then ProceduralMeshComponent. I did both in c++, so I can't say for blueprints. I would like to see how you will implement this, since anything I tried could not beat ProceduralMeshComponent for some reason

[@CodeLikeMe]

Is that so. Did you try the runtime mesh component too?

[@aprivatechannel1152]

​@CodeLikeMe Runtime was extremely fast and it had its own lod functionality which wa really good. I still haven't lost hope on DynamicMeshComponent but unless you want the geometry scripting functionality, I cant find myself using it unless I figure out why its slower

[@CodeLikeMe]

@@aprivatechannel1152 so, what's stopping you from using RMC?

[@aprivatechannel1152]

@@CodeLikeMe Nothing really, just experimenting. I'm currently trying to write my own custom mesh component

I just came back to see wheter you actually pulled of spherical implementation!! Code Like Me you did it!!!!!!! Thank you for this! How much can you scale? Just how big can it be scaled?

[@CodeLikeMe]

yeah. I am still at it. ruclips.net/video/Q3bs5yEkqDE/видео.html
well, making it big is not the problem, making the planet landscape interesting is what I am struggling with

[@SugarKaneNosey]

Use the sphere box option for spherical generation

[@Ksj392os7]

amazing! can you make a video about uvs in geometry script please

[@CodeLikeMe]

I will look into that

[@rahulshinde7781]

Hello, can you tell is there any issue with ue5.3 landscape sculpting? Like when i try to sculpt on it , it's not proper it shape changes as I move camera. Can you help ?

[@CodeLikeMe]

are you referring to LOD transition?

[@rahulshinde7781]

@@CodeLikeMe Yes I guess

[@verbator2241]

I'm really looking forward to you trying to implement this in your World Engine plugin!

[@CodeLikeMe]

Yeah, I'm still learning basics of dynamic mesh

[@DailyPaily]

Can we draw/put materials over edges and vertex with geo ?

[@CodeLikeMe]

I haven't studied much about this topic yet. But I think it should be possible to apply multiple materials

[@mitchellrcohen]

I wonder this too

[@mitchellrcohen]

Soooo helpful. Thank you

[@CodeLikeMe]

Glad it was helpful!
