Problem:

After creating models in BAT (low quality: anything higher just makes gMax crash), and dragging the model in plugin manager into a category and receiving the 'ok' message, I open LotEditor and attempt to replace the building on a lot from the same category with the model i have just made. Only problem is it does not appear in the list at all. The same thing happens with some props i have made or downloaded. This has always been the case except for a few isolated BATs, which were created with identical conditions. Can anyone suggest a solution?

Your problem is that you dont have the lot big enough. Show a picture of the rendered version of the BAT, and we will see how big it is.

Awesome, thanks!...I feel a bit thick now! But it seems to have done the trick, so w/e.
