The reload button really needs to reset current scene before. I can't imagine anyone who would want to reload model with something on the scene already (and if someone would want to do that, he can do it with Import like with vanilla NwMax imo).
Also thinking about whether the "hide fading objects" shouldnt keep also tilefade 2 (base). Because very often tiles contains a black coverage meshes with this settings and if NwMax plus hides them its harder to work with the objects left on the scene because there is disruptive void and usually unlike tilefade 1/4 there is nothing below these meshes. What do you think MDA?
Now, little request. Would it be possible to copy certain clean model routines? Because I found out that when I use CM3 for a tile and then open it in NwMaxPlus and reexport it (without any change) and then run through CM3 again it performs some of the fixes it did before.
This to be more specific:
aabb node turfwok01 set to render 0
aabb node turfwok01 set to shadow 0
unused bitmap stone in aabb turfwok01 set to NULL
