Hi guys, I've finally managed to get my FSX exporter working properly and have amazed my fragile little mind by getting to grips with the dark art of bump-mapping. Only, I've come across a slight um...oddity. As the image below shows, the fuselage of my T-6 has a reflection shine, specular sheen and bump mapping all nice and perfect, HOWEVER, on certain parts of the aircraft, (and as shown by the top of the cowling) a few polygons lack ALL reference to reflections, specular shine and bump mapping. I have no idea what's causing this. I originally presumed it was the bump map as I'd applied a new texture to the fuselage with no bump map and I was getting the specular and reflections displaying correctly, yet as soon as I apply the bump map in the Bump map field in GMax I get these mysterious polygons with missing effects. I then decided to make a flat colour bump map with no raised or lowered areas just in case it was a rogue pixel or something, but alas, even with a flat bumpmap, the issue still occurs. Has anyone else come across something similar when using the FSX exporter?? DB.
