Hi,
I've come on quite far with the .B3D exporter, but I've come across a bit of a problem that one of you guys might be able to fix. For some reason this code block below won't export more then one triangle per node entity. What it should be displaying is 2 triangles, each with a different texture. It's only displaying one. Any ideas anyone?

It's okay people, I've answered my own question :O). Here's how it's done if you want to export multitexture objects in .B3D format.
