I have a couple questions regarding LIVE_UPDATE.
My goal is writing a simple level editor that updates texture and model files on the fly.
Firstly, I initialize hxd.Res like this:
static function main()
{
hxd.Res.initLocal();
hxd.res.Resource.LIVE_UPDATE = true;
new Main();
}
…and then load a simple model (binary .fbx format) with attached texture (.png format):
var cache:h3d.prim.ModelCache;
var obj:h3d.scene.Object;
overrride function init()
{
cache = new h3d.prim.ModelCache();
obj = cache.loadModel(hxd.Res.gfx.terrains.plane);
s3d.addChild(obj);
}
…and when I compile, run and then edit my texture file the live reload does work fine.
But occasionally I get thrown this exception when saving my png:

I presume it’s because my graphics editor sometimes hasn’t finished writing the file yet. And when I keep running, the texture updates just fine the next render loop or so.
Now my questions are: Is there a more elegant solution to reloading the data?
Am I missing something? I feel like there should be a save check if a file is being written to currently while live reloading.
Also: While the png reload works fine, I can not get changes to my fbx file to show up. I guess this is because of the way the ModelCache works? But how would I go about reloading my fbx data?
