Instructions for fixing 'Pure Virtual Function Call' crash

Recommended Posts

What does the plugin do? (Sorry for being an idiot)

Can I just change the script in notepad++? You mention the CK but I'm using mod organizer so I can just edit the script it's installed

Also wouldn't disabled the scale actors in the MCM have the same effect?

SL uses papyrus command "SetVehicle" to lock NPC and player from moving for animations. This command has a side effect that resets or messes up scale of actor. To combat this SL will use SetScale command on the actor again right after this. This command can cause the crash if used rapidly. The plugin removes the side effect of SetVehicle command so that scale is not messed with, which means SL doesn't have to use the SetScale command anymore. That means it can be commented out completely.


Just editing the script is not enough you have to recompile it too. Let someone else do this and hopefully they will post it here, I can't do it either right now.


Disabling scale actor in MCM doesn't accomplish this because that option is about evening scale of actor and not this as far as I know.

Awesome work, gents.


EDIT: Just to make sure I'm understanding this: You have to have BOTH the SetVehicleFixPlugin by h38fh2mf AND the compiled sslActorAlias.pex script by Nukaboil, right? I tried using just the sslActorAlias script and ended up with automatically-resizing npc's in every animation. My PC got raped by the Ebony Warrior, for example, and he shrunk down to about 6ft tall (from something like 7'6", a difference of about half a meter for metric users). I tried manually doing setscale 1 in the console but had to do it over and over as anytime the animation changed the npc would re-scale to the smaller size (my PC is about .95 or so).


Using both together seems to have fixed the issue. Npc's no longer automatically rescale. I still haven't tested extensively to see if I'm getting PVFC crashes with both, but with the sslActorAlias script alone I hadn't had a PVFC in something like six hours of gameplay, where previously it had been crashing on every third scene or so.

I have a problem since i installed this fix. 

The fix in itself work great, but combined with PSQ, it result in a no ragdoll death when using killing sex actions. The NPC will be dead but stil breathing and generaly suspended standing in an ackward angle. The only way to correct it i found is to resurrect kill the caractere in the console.

As a quick note + bump to this...


SexLab 1.62 has a disable scaling option, which will automatically disable all calls to setscale() by sexlab so you don't need to comment them out and recompile the script for this to work anymore. Just install the SKSE plugin here then enable 1.62's disable scaling option and you should be good to go.

1. download and install SKSE plugin attached to this post (not source).

2. disable all scaling in SL MCM.
Side effects:

Thank you for this. I have SL 1.62. Which file should I download; first or second?
