Hello UE4 community!
I’m very hopeful that the new HLOD will solve my performances issues, but I don’t know how to use it properly. I know how to enable it on the World Settings, but what I really would like to know is how to setup the parameters for Hierarchical LODSetup: How many elements will I need? Why every element has always 7 members? etc, etc… If anyone can give me an example I will really appreciate! …and sorry for my English
It seems this question is mostly answered by crickets. (Does that idiom translate? ;-))
Also searching for relevant info, Seems like best bet might just be to start experimenting with it.
Hello Carlucio,
So, the HLOD system can get a bit confusing until it’s broken down. With 4.9 the implementation of the HLOD system allows for multiple groups of LOD’s to be applied to the entire project.
Instead of adding an LOD by use of adding a mesh to that system the HLOD uses draw distances. For instance if you had three boxes in a row, ranging from small to large, and you have this system enabled. For this you could either could have all three added for the 0 level of the system, or have three separate Levels.
If you went with all of them with only level 0 enabled, this is done by not adding anymore levels, then by default at 3000 units of measurement away your objects will be called. You can adjust this so if you were 1000 units away from the nearest box and you had your draw distance set to 1000, only your first box would be visible.
If you chose multiple levels you could assign multiple distances. So everything, if you added more than boxes to your scene, would be calculated at whatever distance you assigned to that level.
The bound radius refers to clustering. For instance if you had a large object whose bounds were larger than a smaller object you may have to adjust accordingly. Even if you have the draw distance at what you want for that object, the bounds might not be big enough to incorporate the entire object.
I hope this helps clarify the new HLOD system and how it can be applied. Of course you will still need to add the volume to cover your entire scene, or the area in which you would like the HLOD to be implemented.
Thank you,
Thank you ,that would be very helpful~
