Return to Arkham City seems to actually have both UE3 and UE4 files in its archives. For some reason the entire game seems to exist for both UE3 and UE4 on the disc. It either means they left over the original files from after they ported it, which would be weird because there are files which weren't in any version of the game before it (like Playable_Joker) or it somehow uses both files from both engines simultaneously somehow. The only way to know for sure is to edit a text file or something in the UE3 side of the game and see if that makes any impact on the game.

At this point though, I'd call it incompetent development because without the defunct UE3 files cluttering the disc, they could have fit the entire collection onto one disc instead of two. It doesn't make sense why they didn't do that if the game doesn't use both sets of files in some capacity.

Sorry about the new thread, it wouldn't let me post in the old one for some reason.

Umodel crashes when trying to open up any umaps/uassets https://drive.google.com/file/d/1JWXzIvs9rzN5UONWhhxa6r3ibQhCYqXN/view?usp=sharing both are from the UE4 portion of RTA, not the UE3 files. Though, the UE3 files don't work work either. As to why the game has builds for both on the disc is anyone's guess.

I see no point of doing any job for a game which already supported for older versions. I mean - all "original" Batman games are supported, so there's no point working on remaster which only has changed lighting.

It's not just changed lighting. New models, entirely different UVs too. There's also some cut content and files that aren't even in the game, like the Playable_Joker files for City.

Ok, UE4 part is probably feasible to do. But not UE3 one, unless PC version of remaster will appear.

That's fantastic news, thank you. The UE4 chunk is what we need most anyway Smiley

Update: Weirdly, some files in Return to Arkham Asylum (UE4) can be opened. The model for the head, body and cape of Batman as well as the diffuse for the head and body. The cape, eyes and any normal/spec maps can't be extracted though for some reason. I think it gives an error about an unimplemented function. It's also the first time I've seen each model in a game get its own TFC file containing individual textures.

UModel doesn't have a word "unimplemented" inside. Are you working with umodel?

UE4 doesn't use TFC, it's UE3 only.

I'm not sure what to tell you then. Perhaps it's some kind of hybrid engine? There's definitely tfcs in the UE4 portion. Here's the TFCs from Image0\asylumue4\content\paks\project\AsylumUE4\Content\Packages\Characters\Joker\Maps\_TEX_ https://drive.google.com/file/d/1zNV15eXElyhgvcs-t0uUJqTEK84t75YQ/view?usp=sharing (unpacked from the PAK file using QuickBMS)

The unimplemented function error occurs when running umodel from the gui. Certain umaps/uassets can be opened, but most just crash, strangely.

Here's the error if it's of any use to you. https://drive.google.com/file/d/1ol3s0HIKF8wr22djUI-F1zlVyW6WnI-F/view?usp=sharing

Those doesn't look like "classic" tfc, they looks like uncompressed ubulk files.

Ah, I see. "Not implemented" ... It attempts to seek to negative file position, and system treats this like seeking to a very large position (> 4Gb), what I didn't do as it is not needed there. If I'd implement it, the error would still appear, just a different one (attempt to seek past end of file).

That's weird though, right? I've never seen a UE4 game use tfcs, even if they could just be renamed ubulk files. If you need any more files for Return to Arkham Asylum or City let me know.

Yes, it's bad. This engine has too much custom things, and it's not for PC (what makes executable file analysis much harder than for PC, if I'd consider it).
