Lil addition:

Animations are ACL compressed, seems openable with experimental ACL build 2.1

I noticed now that what i wrote could easily be misunderstood   Angry
I meant that: if you try to open an animation by itself and read the console, with normal umodel it'll tell ya that the animation is acl compressed and won't be loaded, if you use 2.1 version it'll load, 'cause the skeleton work, it's the meshes that are causing problems, let's hope that spiritovod may solve this "issue" too  Smiley

Static meshes and textures works fine with latest official umodel build (1590 at the moment). For skeletal meshes, animations and better materials support use specific build from this topic with game specific override option.

    It turns out I forgot  Grin Grin Grin
Download latest official umodel build from the site and place specific build in the same folder with it.

Hey, @spiritovod
Thank you for your work on the custom build of Umodel with ACL.
I was exploring Raven 2's game files and I wanted to understand how the character, body proportion, customization works.
Since I couldn't find any skeletal meshes with blendshapes (morph targers) - I was wondering if this Umodel build doesn't support them or they're using bone offsets from additive animations for this.

Thank you in advance.

@Sydie: Native morph targets should be supported, but not sure if the game is using them at all. If you didn't disable them at startup screen, but can't find them in meshes (they are shown at the left bottom part of the viewer, if present), that means there are not any. Other possible dynamic customization options, which can be used by the game, are probably out of scope of umodel.

Is there no way to extract a shader?

Also, could someone upload the .pak file?

@Drawing: It should be fixed now in the updated specific build. Not sure if it's worth to apply this check for invalid bulk data to all games, it looks rather like some game specific stuff (even though engine itself should handle it).
