Most of the mesh fixing is done, enough for a first pass of texture mapping to happen. Right now I'm using a tile map found on buran.ru. And so far it looks good. I'm still in need of someone to turn the template texture into a real texture.
So using the various images as guides, I've got this so far. That's all the tiles on the midbody, excluding the blankets that covers the rest. Once those are in place, I'll move on to the aft body, so I'm working myself aft. I'm saving the more complicated forward body for later. This is slow going but progress is being made. Now this gives me an idea of how tedious it must have been for the KSC Orbiter TPS teams working 24/7 for 1½ to fix up Columbia's TPS ahead of STS-1.
Basic thermal blankets added to the midbody along with tweaks to the tile border color to make them blend into each from a distance better. And yes, the blankets did have an off-white, nearly grey color to them with white blanket interspaces.
