dùng được nhé bạn

Bạn có thể cho mình hỏi thêm card tối thiểu để dùng đựoc ue4 và hiện nay có khóa học nào tốt k bạn.

ok ban, thank ban ung ho :D

chắc google driver nó tự đổi link rồi, để mai mình share lại nhé, cảm ơn bạn :D

@@trinhtu3dartist Sorry, i meant to there is a feature called hardware or geometry instancing. Looks like this feature rebranded as nanite in unreal engine.

thank chú, a chỉ đang băn khoăn ue5 dùng đc umu nữa ko :v

@@trinhtu3dartist e nghĩ là có, cái UMU bọn n viết lại cái TS Tool của Tom Shannon th mà, nguyên lý kiểu n tìm tên asset trong thư mục r paste vào đúng vị trí, giống copy paste đối tượng giữa các level thôi. Với h e nghĩ nên nghiên cứu cả Datasmith , bản thân a tự Unwrap r set Datasmith nhận cái kênh đó cũng được mà.

data smith nó bị cái khó chịu mà a ko biết xử lý là sửa model mà update lại thì vẫn phải dùng import thủ công, nên vẫn phải hướng dẫn import thủ công trc

@@trinhtu3dartist reimport ngon mà, cơ mà n reimport từ cái file datasmith nên phải export lại cả cục. Kết hợp với chia scene ra nhiều phần r export riêng cũng ổn. Vật liệu datasmith n xử lý cũng tạm nữa, e thấy n khá hợp cho làm video. Tất nhiên là làm tay tất vẫn ok nhất mà mất thời gian quá.

@@TrieuDuongLuu đấy, vấn đề là sẽ cứ phải export cả cục

cảm ơn bạn ủng hộ :D

thank bạn ủng hộ :D

a cũng muốn vậy mà h tiếng anh còn kém, nên để sau này làm :v

không hihi :3

youtube ko có nút phẫn nộ nhỉ

i dont have rx590, but i think its good :D

cảm ơn bạn :D

thank bạn :D

quý hóa quá :v

@@trinhtu3dartist Đang học có người làm tut chia sẻ thì còn gì bằng :D

làm Tut mà có anh đại vào comment cũng không còn gì bằng ạ :D

:D, thank bạn, nhớ đăng ký kênh để xem tiếp clip nhé bạn :D :D

no Sir

This.

@@trinhtu3dartist then whole comparison makes no sense. if you bake LODs without nanite, then it would

@@xamogxusx Still useful if you don't have any use for LODs, such as making a concept image instead of a game. Unless you absolutely have to use LODs because of performance, in which case Nanite solves anyway.

@@lukaskawalec9806 but you are baking LODs with Nanite... So we are comparing Nanite with LODs Vs UE4 without LODs

I think it's still useful it's just that you don't need to create a lot of LODs to make the scene optimal

@@trinhtu3dartist yea but did ue4 not have auto lods if you enabled them? I mean, i never created lods manualy, always used the auto lods in ue4, so i don't realy understand what is different between ue4 with auto lods and nanite

It doesn't retriangulate it, it just splits the mesh up into meshlets that match across mesh LODs so the GPU can efficiently load different LOD levels of different parts of a mesh, and also manage LODs and draw calls directly on the GPU as well. This isn't a specifically "Nanite" feature either, Nvidia came up with this a few years ago and it's now part of D3D12_2/Vulkan. But it looks like Unreal has implemented the feature with some compute shader hacks to support older GPUs like the 1080. So yes, optimization is still important, it's just that the engine will make it less of a concern and make up for your failings. We don't want to load up game downloads with terabytes of raw 3D scans for models. And ideally you'd still want to handle people using HDD instead of SSD, HDD is harder for this system to run on.

​@@invertexyz Nanite does a lot more than meshlet based rendering. It's also not an hack to do meshlets using compute shaders, it's just a bit more complicated and a bit less efficient. Assassins creed unity, Doom Eternal and all modern Frostbite engine do some form of compute shader based meshlet/triangle culling. Nanite builds a hierarchy of meshlets/clusters so that it can switch to a less detailed level in the distance. The important part is basically that the LoD decision is not done on mesh basis but based on those hierarchical clusters. It also makes sure that there are no visible seams between those. The higher hierarchies are doing some form of automatic LoD/retriangulation. Nanite also has some custom rasterization approach that mixes compute shaders with hardware rasterization. The issue with the later is that it's pretty slow for such triangle densities. I haven't looked into the code though and there is not much information about it yet, so I don't know for sure how the rasterization works. My guess would be something like hardware rasterization for a less detailed clust and then compute shaders for the micropolygons

@@DoomTobi Mesh shaders can do the same thing, that's one of the main advantages of mesh shaders is being able to do the meshlet-based LOD levels instead of mesh/object based. Mesh Shaders give you full control over the geometry pipeline and direct access to memory management, which unfortunately required an updated shader model and thus is only supported on RDNA2/Turing and newer architectures. Nanite is indeed a custom solution and why it works on older hardware, they are relying heavily on compute and resource bind tricks to do most of the work of course though and they did recently just add mesh shader support to the UE5 source code, so perhaps they'll attempt to accelerate it with mesh shaders as well when possible.

Nanite generates LODS automatically tho

@@VerniMain well, you can generate lods with a couple clicks in ue4

but... that's the whole point. nanite skips having to make lods. it's not about saving performance, it's about saving development time.

@@zedsdeadbaby its about both. It does lod automatically and saved ton of performance

+ with Nanite's LOD, there is NO pop ups.

ok, i will be try

foliage doesn't work with nanite. It has to do with how foliage is rendered in traditional way that doesn't work with nanite

@@CyberWolf755 thank you

Foliage is worked

@@trinhtu3dartist no, only non deformable static meshes will work with nanite
