Landscape HLODs are broke when build from Editor. See repro steps above. I have not provided a repro project as it uses the open world starter map. [Attachment Removed]

Yes, you’re correct we will be using a similar approach as suggested by Yanchen in previous comments. Thanks, David [Attachment Removed]

Hi Tom. Unfortunately, no updates at this time. [Attachment Removed]

Hi, just as a quick update here, it was determined that this wasn’t a problem with the landscape code, so this is being moved to the world building team to investigate further. [Attachment Removed]

Hi Tom! There were actually multiple issues compounded here. You should be able to resolve them by grabbing the following changes: https://github.com/EpicGames/UnrealEngine/commit/2a4ac5784771637bf6493514a3f84b50c4b6b437 https://github.com/EpicGames/UnrealEngine/commit/534017e5432da154322ac675071…

Hi Sebastien, Sorry for the late reply. Thank you very much for sharing the changes. We’ve found the change to force compile all required shaders helped, but the others did not in our project. We’ve made some additional changes that helped us; I’m getting the team to compile the information so I ca…

Hi Sebastien, We have observed the same issue, and it indeed caused by RVT not being rendered (UE 5.7). Currently, when Building HLODs: Source World registers it’s RVT Actors and Components. When building HLODs a new temp working UWorld (named BuildHLODWorld) is created. HLODs being built load u…

Hi David, Great analysis - your diagnosis of the root cause is spot on. The RVT actors and components not being cloned into BuildHLODWorld is indeed the problem. Regarding your two-part fix: The LoadSourceActors modification to collect ARuntimeVirtualTextureVolume actors from the source world is …

Hi Sebastien, Now that the HLOD texture is generated, we have noticed some black borders around the edges of the HLOD texture? The result is that when all HLODs texture are generated, it looks like there are black seams and visually looks like a grid is overlayed on top of the landscape. Is that …

Hi all, We have found similar. It has been reported in the community forums: [image] Hlod RVT , seam problem Programming & Scripting Hello there, im having problems getting rid of Seams between the Hlods of my landscape, im using RVT to optimize my landscape,…

That grid like pattern has been fixed with the following change: https://github.com/EpicGames/UnrealEngine/commit/2a4ac5784771637bf6493514a3f84b50c4b6b437 [Attachment Removed]

“We are seeing good results, but are concerned that this might force Fallback mesh to be used when generating the HLOD geometry? What impact wil this have?” [Content removed] which is really desireable if you are using Nanite for the rest of your project. Ultimately if you are using Nanite and SRV…
