When I have the new Formula BMW mod installed, I can't view or select a Zonda in All Cars & Tracks, even though it's a listed car. I checked the Zonda because I'd had trouble with it before.

No big deal, since I wouldn't want to run those two together, but it looks like there are a couple ways to solve this.

Back in September, when I had trouble getting the Zonda to show up in All Cars and Tracks, I posted the question at RSC forums.
http://forum.racesimcentral.com/showthread.php?t=266750

A solution was to uninstalled one or more other mods.

A reply from ISI T-Bone:

"There's no limit in code to the number of cars, *but* I think there are a few ways that conflicts or the way mods are done can cause problems when using the All Tracks and Vehicles mod. One possibility is when mods specify different directories to search for tracks/vehicles/sounds/etc. For example, if there was a mod that had all their sounds in a different directory, then the sounds might not work when playing All Tracks and Vehicles, because it uses the default sound directory.

Basically we released the All Tracks and Vehicles mod, despite some known issues like the above, because there were several unofficial versions floating around and we thought it would be a good idea to standardize it. I know this doesn't really help, but perhaps it provides some explanation."

In a recent RSC thread, someone had trouble getting the Gallardo mod to work with All Cars & Tracks (ACAT).

From a reply by Dave Purdy (Post #58):

"Yes it has been tested with My own ACAT rFm, as well as the ISI one that came with 1150. However, there are a few other mods out there that interfere with all of the ACAT rFms, by modifying the <VEHICLES> default path. With those mods installed, an AllCar rfm is virtually neutralized. I run multiple installs of rFactor to avoid this. Unfortunately a couple of these "offending" mods are quite popular, but the creators did not want their cars mixed with any others for some silly reason, lol. To identify these mods, look in the rFm for a Config Override where it says "VehicleDir=[SomethingOtherThan: Gamedata\Vehicles]

The only mods that will work from an ACAT rFm are possibly ones where rFactor read their rFm before one of these mods with the over ride. This was not a NECESSARY thing, but something done to prevent some people from having fun with adding extra cars to the mix. Those mods are too "pure" to have any other cars around, lol.

There is another workaround that you can do, but requires everyone to have the same files. Take one of my All Car rFms, and modify the Vehicle filter to allow ONLY the cars you want, like PCC05 and GallardoGT3 and whatever else, naming them specifically. You will be able to race offline, no problem. If you have friends you want to race with, rename the rFm and rename the series in the top line, to make your own custom rFm, and distribute that amongst your friends."

"to make the Gallardo ACAT compatible you can edit the gen files

change this
Code:
SearchPath=<VEHDIR>
SearchPath=<TEAMDIR>
SearchPath=Gallardo GT3

MASFile=Gallardo GT3\GallardoGT3.mas
MASFile=cmaps.mas


for this
Code:
SearchPath=<TEAMDIR>

SearchPath=<VEHDIR>
SearchPath=<VEHDIR>\Gallardo GT3

MASFile=GallardoGT3.mas
MASFile=cmaps.mas

this should work and allow the car to show up in game and on the spinner in ACAT mode without creating missmatch."

Sorry for the long post, but it might help some time. A simple solution is to try uninstalling one or more other mods. I haven't tried the second solution path yet - file editing.

I've noticed this in other places, too. Mod makers get snippy with each other and do things like this in an attempt to make people not want the other group's mods. Whatever.

Very useful knowledge. Thanks Papa_K.

In due course I'd like to make your post a sticky and eventually copy or move it over to the FAQ for future reference.

Sounds good. Surprised this kind of thing isn't in a FAQ at RSC forums. The question keeps coming up.
