Texture export from decrypted Rocket League UPK files

« on: October 04, 2016, 22:35 »

There is a tool to decrypt Rocket League UPK files I am using. UPK explorer seems to suggest that the files are successfully decrypted.

I'm trying to get access to thumbnails that are contained in the UPK files to export a TGA.

An update dropped today with new items, umodel is not able to export textures from those new items.

Here's the error it fails with:

Code:

This game actually was not "officially" supported by UModel. The forum just have information how to extract everything. You could try disabling texture loading to avoid crash.

It seems like the devs made a couple minor changes to the file format, which causes UModel to crash when loading because some offsets are wrong or something. Small .upk files load fine (like Hat_Pigeon_SF.upk). Could you add support for this?

Sorry, this game is not in my "todo list". I'm rarely working with encrypted games. Also, I'm having less and less free time last year, so I must carefully select features for UModel - pick the most important ones and drop less important.
