Thread: lwo3 importer -> open source

  1. #1

    lwo3 importer -> open source

    this one:

    https://www.lightwave3d.com/assets/p...y/lwo3-loader/

    make it open source, so other can integrate the new lwo3 file into their projects.
    One of the reasons there was / is a wide support to lwo was that it had their loader
    aviable as source and documented.

    Yeah, this needs to occur ASAP, and ideally with a BSD or equivalently-permissive license.

    Will the lwo3-loader work with much earlier versions of LW?
    Or maybe i should ask, what versions of LW will the loader work?

    Theory: it works based on the new engine, therefore, no.

    It doesn't work with 9.61 32bit. Says the loader failed to load.

    Really shouldn't matter, it's back-porting LWO3 into older versions in the first place, so it isn't like ANY older versions have the new engine.

    As gar26lw noted, I suspect the main issue for back-compat. is due to it being a 64-bit plugin (and LWO3 is a 64-bit-native format, IIRC).

    The SDK documentation has a full format description of LWO3, assuming it is accurate, just like it has had for the previous formats. I always assumed that documentation was the reason why LWO had wide support, that it was a well documented format. Over the years, or rather decades *shudder*, I've whipped up a couple of LWO readers, and at least for me it was always based on the format documentation.

    Going by the doc there is not a single 64-bit data type in LWO3 (not even double floating point vals) so there shouldn't be any 64-bit requirement dictated by the file format.

    what apps were the readers for?

    Oh, not for other regular 3D apps in my case, but readers/importers in my own projects (3D engines and tools).

    That doesn't sound right, are you sure you're not looking at the prior version?
