Hi everyone, thanks for reading. So i have messed around with the lot editor and some of the other tools the community have made (disclaimer; PIM intimidates me with its menus) and i have made a few posts for specific problems but i have made this thread to hopefully tidy this up going forward where i can ask all my questions in one place, hopefully show what i'm doing and if i'm very lucky, help some folks out who lurking the thread who have never tried lotting to give it a try too.   Anyway, first question is a simple one i hope. I am trying to edit ChrisAdams 'ALN gravel path lots'. These display for me with no base texture (think perhaps a terrain issue or a missing texture naturally). Anyway, rather than hunting the dependency down i decided to put my own favourite grass texture on the lots, (i think it is the ID that MGB's TGN uses to overide. In my LE it is 0x251c2000). This will obviously make the lot work again and also hopefully keep everything looking nice and matching. My problem is that all the different paths i downloaded are in a couple of .dats:  'ALN_Gravel paths lots.dat' 'ALN_Gravel paths -- aditional lots.dat' So i can open each lot in the LE, and attempt to save it over the 'old' lot i get this message Which does seem fair, as this lot presumably 'lives inside' one of the two .dat files somewhere and so there is no lot file to overwrite. If i 'save as' and give each of these a new filename as a .lot file, the LE does let me do it. In fact the filename it gives is probably the name of the actual lot in game. Am i basically best to 'save as' each different lot as i edit it so i create 15 lots instead of 2 .dats, and then throw away the old .dats that i downloaded when i'm done? Or is there a better approach that i havent considered. As a secondary question, does anyone know of a tutorial for things like changing the text displayed in game for a lot when you find it in the menu / menu icons etc? - i appreciate that this one is probably trickier! - My lots obviously just display as a little picture of them, and if i make more its going to be tough to work out what is what as there are a lot of variations on a theme. If i can get some little icons to represent what they are along with a text description i'll feel like i'm at least starting on the right foot.
