<br>
I created a test plane and subdivided it to make many faces and extruded every other one to give it a little depth. The face count of my plane is ~43k faces. I UV textured the sample plane with a jpeg, one with a png, and one with no image. I converted each to a .obj. The no-image had about the same poor performance in loading as with the jpeg or png. Note that loading time doesn't matter if I convert to a osg or ive first and then load.<br>
<br>
So, for some reason, OSG 3.6.x is taking a lot longer loading a higher faced/vert count .obj (or osg or ive) object than 3.4.1. This is a show stopper for my customer, and I'll have to stick with 3.4.1 until something is figured out.<br>
<br>
Suggestions? Thoughts? Are there any optimization switches I've missed that was not default before building the 3.6.x series?<br>
