Hello,
I was hoping you guys could help me and point me in a direction.
I received a big FBX file from a contractor, depicting a scene originally created in Autodesk Revit.
Im afraid getting the original files to do the export myself is very unlikely so im trying to work with what i have at this time.
Now the whole thing is basically a terrible Export since at the time nobody thought about using unreal to visualize it. Nowadays you would usually use datasmith.
It preserves the hierarchy and combines multiple instances of meshes along other optimizations. Now this is not the case for FBX which to my understanding saves each mesh respectively ending up in this unorganized mess.
We are talking 1.7 gigs with just over 130.000 meshes it is made out of and god knows how many materials and textures. I tried importing it into Blender but without success ending in Blender crashing every time despite having a beefy enough pc. I managed however to import it into Unreal Engine but its either combining all meshes into one which is terrible since i want to work with the child elements or having each of the 130000 meshes individually. The usual solution which i stumbled upon when researching this said to drag these into a Blueprint having it reconstruct the scene. i imagine this works for small files with few meshes but in this case i haven’t managed to get very far with this method resulting in alot of crashes. Lets say i got it to work tho with this method id still have f.e. doors made out of multiple meshes so working with them would still be a nightmare. Not to mention performance.
Tldr: Is there a way in Unreal/Blender or other tools which could help me make it more manageable or for that matter at all possible to work with a file this big and salvage some of it?
Thank you for reading and i hope you have a wonderful day!
