@Reacon yes that's correct, so when i add on any car i always use my trainer to spawn them, but since my update.rpf in the mode folder is a different version from the original update.rpf, my trainer is not working crashing and that led me unable to spawn add on cars.
I just think that cars (replacements at least) and outfits should spawn / be available right when the game starts... or should they? If not, then that would mean these items are not installed properly. Hard to tell really.
Ok, I see now. Well, I'm not an expert as far as this tool is concerned. Sounds like fun though.
I don't know about an autoloading option, but I have a vague feeling it should have one! After all Menyoo uses nothing else but .xml files, so perhaps there is a way to do it. Maybe I'll check it the next game session.
As far as I know, Native Trainer's on/off key is F4...
Are you sure you have the numpad active?
I remember this message you mention and I've been there. If you get a "scripts reloaded" message, that probably means that there is a mess in your "scripts" folder and the GTA V directory. Deleting duplicate files and "leftovers" is what usually helps.
These variables below control the exta added model information on vehicles and tuning parts and the added textures, I think. (I've take these from an older gameconfig.xml so values are edited by now btw!)
I'm sure about the section containing TxdStore and Vehicles, MaxVehicleModelInfos and MaxExtraVehicleModelInfos, eg with the following poolsizes, when I crash when adding additional vehicles, increasing those four values alone breaks that barrier. For a while.
Blip noises you say... Is it possible that you have some other mod or a script enabled that uses the same key shortcut? Mods that use identical keys often go angsty-ass, ape bananas. Some are bound to conflict with one another.
Read the other post I just quoted you in. I got rid of the blip noises as it was another mod. Now when I press F7 literally NOTHING happens. It doesn't pop up nor does it make a noise.
It's a rather strange bug and I don't experience it.
I really doubt if other mods or scripts have anything to do with this problem... I also have "Street Races", "Menyoo", "Map Editor" and countless other scripts. Some of them very old. Still, like I mentioned, I have proper collisions on objects (at least the ones I tried, but I think it's safe to say others work too) as well as the ramp you mention.
Now, Map Editor will work with any Native UI version, including the newest one. It's just an interface resource that displays the menu. It should have no influence on the way a mod works. I have an updated UI and notice no problems when using Map Editor.
In my opinion, your copy of a Map Editor itself needs an update. Maybe it's just that you have an obsolete object list where stunt ramps are present on the list but are otherwise "empty" entities with no data to guide their behavior. Consider updating an object list or the Map Editor as a whole, and let us know if that helped.
