Max to UE4 Maxscript Help
Hi guys. My apologies if this is the wrong subforum, it's the only one I could find that seemed the most relevant.
If anyone's familiar with Tom Shannon's TS Tools for importing Max objects/scenes into UE4, I'm basically trying to modify that to make it a little more "one click solutiony." With the TS Tools you have to select all of the master objects (either singular objects or one of an object which is instantiated) in your scene manually which can be tedious. As well, when importing into UE by going to Edit -> Paste, the meshes your UE scene are populated with default to the DefaultCube mesh from the engine files and not the corresponding mesh from your Max scene which means you have to manually replace each mesh with the correct imported meshes. While this doesn't seem like much of a problem with smaller groups of objects or scenes, I've had to deal with scenes which have hundreds of unique objects and this becomes rather tedious.
I've only just begun delving into Maxscript in the last week or so and have made some good progress, but I've hit a snag and I'm really stuck as to what to do. I think I know the logic, but I'm just not sure of the proper order/syntax.
My script at the moment is capable of looping through the scene and picking only one of each kind of object (e.g. if you have a cube which is instantiated 5 times, it only picks one) and exports those accordingly as the "master" file. I also have dissected the TS_Tools script and implemented a similar system which can copy all the transforms of every object in the scene and generate a clipboard text for populating the UE scene based on the objects and their respective transforms in the Max scene. My problem has been trying to change the mesh which UE populates itself with (at the moment just the default cube) with the actual corresponding master mesh from Max. While this works fine for singular objects, it does not work for instantiated ones and only populates the first instantiated mesh and not the others.
The part in question in my script is the following:
StaticMesh=StaticMesh'/Engine/EditorMeshes/EditorCube.EditorCube'
EditorCube is just a placeholder and I would like to have that for every object in the scene, if it's an instance it would reference the "master" exported file and use that because that is the name of the file which will be exported into UE4. (e.g. Cube00, Cube01, Cube02 would all reference Cube00 as that's the master file).
My apologies if I'm not explaining this properly, I'm a little burnt out at this point from trying to solve this. If you want me to clarify anything I've said I'll do my best.
Here's the truncated script below so it's not super long:
