    Any way to export LWS?

    Is there any 3d software that can import or transfer a LWS? and on the same subject what programs can import a LWO?
    Or even an OBJ with surfaces? (I know pretty much all 3d apps can handle an OBJ)


    Cheers

    I'm not sure on a scene file although they're just text. A number of other apps can probably handle objects. Both Layout & Modeler recognize OBJ's natively.

    3D Coat opens and exports LWO files, and I think Hitfilm opens them.

    Blender..some versions can import LWO...though mostly 2015 and not the 2018-19 versions. lwo 5
    Same with houdini, same with vue..same with terragen.
    Vue can also export a scene in lws format.

    Ya, as long as you've the .mtl file. It'll only be the basic surfaces. You'll need to rebuild any PBR type surfaces.

    I find importing objs with surfaces a bit 'Hit and miss' Meshroom for example always exports with working surfaces fine, realitycapture 'never' exports with working surface (even though there's always an MTL file,) ive found that most times when importing an OBJ that the surface just doesnt come with it even with an MTL. Is there a plug-in to sort this or is it just dependant on the software the obj is coming from?

    FBX may be the interchange format you're seeking, especially going back to your original query about LWS.

    I suspect on the export side for the mostpart. Took me a lot of T&E with OBJ's out of Daz to find the best working combo for how various things got split up when imported. On the LW side, there are options for OBJ as well.

    If you use the OBJ One Layer option, you'll always be safe but all will be in just one layer. If on the other hand if the OBJ export has been set up for it, turning that OFF before importing will give you separate + Named layers.

    If Modeler crashes when opening an OBJ, turn One Object back on & try again.

    Any exporter should be making an mtl even if the surfaces are just using colors, but only the basics if any maps involved of course.

    You cannot expect exporting LWO and/or LWS to reliably support LW surfaces. They use LW-specific procedural textures, nodes and plugins etc.

    To sort of export LWO to 3rd party app and/or game engine you need to bake LW surfaces to image maps.
    This will help in some situations when node/shader is not using e.g. ray-tracing or similar techniques.

    I made plugin which helps baking a lot of objects at once:
    Batch Baking Camera
    http://batchbakingcamera.trueart.eu
    It requires very little setting up time from user. Much less than LW baking camera.

    I made plugin which helps baking LW scenes with animations:
    Bake Scene
    It can bake entire scene to the single .lwo with .mdd file with changes to vertices.
    It should be loadable anywhere which is supporting .mdd file.
    LW-specific motion modifiers, bones, deformations, nodes, are gone.

    I agree with raymondtrace. FBX is supported by many programs and it supports objects from LightWave and many basic object/surface properties, in addition to cameras, lights and motion data. Mostly likely, you'll need to re-work the surface settings in the other program if that's important, but UV maps and possibly the texture maps should come through.
