Ah, yes if the Texture entry is missing then adding it manually will not work because it also has to be assigned to each Polygon. You will not want to be doing that manually since usually there are a lot of polygons.
We need to find where the Texture is being lost in your pipeline. I’m not familiar with the syntax of Collada and X but if you open then up you should be able to search for your texture and see if it is in there. Then we can at least know if it is exporting from Blender without the texture or if the texture is being lost in the conversion to EGG. If you like, export something simple like a cube and post the contents, and I will take a look.
UVs in the EGG file can be named or unnamed, so the “UVTex” is just the name given to the UVs. This is probably OK.
There is a very new exporter being worked on for Blender 2.5, see here: [url]Yet Another Blender Egg Exporter (YABEE)], though I don’t know if it will suit your needs or not yet.
