2. These will likely be easy to do as the rendering would probably remain ok.
3. I actually went through all of this before the HD collapse, but need to do it again, I think the reduction was quite large.
4. Future stuff can easily be done like this, but the historic stuff might have to stay for a while until the mod is ready for another major release.
TR textures. I couldnt off the top of my head even recall putting these in. I do remember someone asked a year or so ago to include various items from all over the place, mostly desert stuff. As I have gone through the mod, wherever I used stuff myself I always either credited people or where possible contacted them to let them know, or if neither was possible, kept an eye out for when they re-emerged. For instance the Dune stuff, however the maker seems to have disappeared so either we dont use stuff, or use minimally and credit, then ask retrospectively if all is ok, when the maker re-emerges from wherever. Also there are a few redundant bits in the mod as you have probably discovered that seem to have been overlooked by my own daft fault, ie; not cleaning out a couple of mods I have tried out, before packing everything up. The last reason may well be that one of the people who helped with the mod beforehand may have provided them and not bothered to let me know where they were from. (happened a couple of times I can recall.) sometimes people just arent clued up on how to and why to credit others. A bit annoying. I see my stuff crop up now and again, but so long as credit is given I suppose...
