Drag and drop may not work if you run OpenIV as Admin. You can replace several files at once using "Add" button.

So when you open those files in OpenIV you still see original models?

What do you mean "nothing changes"?

After each GTA V update you need to copy new version of update.rpf into your "mods" folder.

​Yes. Only ASI Loader is requested (obviously). OpenIV.ASI and ASI Loader are version independent.

You can still use file-based mods. Both OpenIV and OpenIV.ASI works fine with the latest update.

​Try to use different texture compression while import or better import DDS files.

If you so sure that is the OpenIV fault, I have a great solution for you: Use SparkIV, it has no updates for ages. And btw, as long as your Resource (.wft) is created by zModeler and not OpenIV, also OpenIV can show it in viewer, it is probable zModeler fault.

At the current time - no.Not sure but at least you can try to rip models from the game with 3d ripper or something.

Max Payne 3 .WFT and GTA IV .WFT has different version, which means the file format is different. zModeler is supports only GTA IV .WFT.

You need just select folder where your GTAIV.exe is located.

I have tried that version as well, no luck :( What error it show?

This is NOT A GOOD advice. Does OpenIV shows any errors? Are you sure that your file is not corrupted? Do you have backup to check this on an original IMG?

OpenIV works with audio files just fine, without any issues:

This issues was fixed a long time ago in the latest hotfix for 2.1 release, please stop to mention it. What error OpenIV show when you trying to open a file?

The issues with IMG editing was fixed in the latest OpenIV update.

ALL Who still have EZCompressionError(OpenIV)/ZLIB20(Game) errors I need your corrupted vehicles.img because I still unable to reproduce it by myself.

Unfortunately, I still can't reproduce your issue with game crash.

As I say on GTAForums, the issue with "no cars showing" was fixed in latest hotfix update. Does OpenIV shows any errors ow what?
