Unreal Engine FBX problem and Merge and Replace Actors

Bumblebee · May 2019

Hey Guys,

So I recently made a small scene in max and wanted to bake some basic lighting in UE4.

Everything here is unwrapped, (some are not 0-1 space). However when importing in unreal i get this:

If I import the same fbx into marmoset, everything seems fine. Also I had put the walls in the same group so I wouldnt get any lighting seams, I didnt merge the verticles but they re supposed to be sharing uvs and groups. However when in unreal most of my objects in the scene seem to not have a connection to the bottom shelf meshes. I cannot select individual meshes in the scene and change settings such as LM resolution but I can only select the entire mesh/scene . I was expecting the meshes to be split similar to how they were in max (walls obj, sofa obj, boxes obj, table obj...).

Also I noticed when i merge some modular meshes using the dev tool and then hit replace actors with the merged tool, the scale and position always seem off (bigger and moved away, original mesh stays there)

Any help? Kinda new to unreal

delete the fbx, re-export and when you reimport look through the import settings more carefully - you should find most of the things you're looking for.

Delete the fbx from unreal and import again? Same issue, I looked in the settings and couldnt find the options i was looking for. I tried changing some stuff but no luck. I am new to the engine so its a bit difficult.

There's an option in the import dialog, something like "combine meshes", uncheck it and unreal will import the pieces separately using names like filename_meshname.

also, someone know the issue about replacing merge actors? Ive seen in a tutorial how the mesh got replaced,however on mine, the scale, position is sometimes so off and the meshes that were supposed to be replaced dont go away.
