UShock for Lineage
« on: August 06, 2011, 07:14 »

This is a first public release of the Unreal Model Viewer. It is available here: http://www.gildor.org/en/projects/umodel.
I have plans to publish the source code of this project if there will be interest.

Do you still plan to release the source code for this? I'm about to modify UShock to support Lineage II to make an open source geodata generator/editor, but it would be much easier to start with Lineage II support to begin with.

Even a list of differences between the UT2k4 format and Lineage II would be of great help.

Umodel and Ushock support different things. Umodel doesn't do anything with map data, Ushock does nothing with skeletal meshes.

You'll need some help with static meshes and textures - I'll help you. But first, you should load the maps Smiley

All of the BSP in 22_22 (other than the skybox and big thingy surrounding the entire damn world).


I'm working on terrain next, but I need textures for that.

Also, just as a note for G16 texture support. It's just a bunch of uint16_t in row major order. I just can't figure out how to read that weird text data that comes before the actual image data. They look like shader fragments.

Anyway, there is no G16 texture file formats for export ...
Yes, that "weird text data" before texture data is texture metadata.

Terrain!


Btw, here are the scripts: https://github.com/Bigcheese/L2MapExtract

I've decided that I hate the UShock source code (really, reimplementing the standard library?). So I'm going to write a new library once I figure everything out.

Author has tried to implement Unreal-like serialization system. But the problem that he had used STL streams, which are not flexible enough.

Static mesh exporting works. The format is exactly the same as UT2k4, but there are a few (6/94 so far) that I can't export because they seem to have the wrong number of indices.



Placing them is a manual process at the moment, so I only placed a few. I have the location and rotation, but it's in a different file and 010 Editor isn't really setup to do that.

Changes have already been pushed to github.

As a person whose day-job is working on a C++ compiler and standard library, they are indeed flexible enough. And he re-implemented everything, not just iostreams.

My Lineage StaticMesh loading code is exactly the same as UT2004.

So I've actually gotten rather far on this.



However I need help on two things. The first is property arrays. Specifically the Materials property on static meshes. I've tried what UShock does, and it doesn't seem to line up with the data. How is this encoded?

The second, which I doubt anyone knows, is how is collision stored for static meshes? I know it's either stored as a kDOP, or an index to a UModel. However, I cannot seem to figure out exactly what's going on ;/.

Strange, there is nothing Lineage-specific in my StaticMesh serialization code. Please be more specific describing your problem. Probably I should look at your code.

Yes, UE2 uses kDOP. Unfortunately nearly every UE2 game have modified this part of engine, so I've decided to completely skip kDOP serialization.

Not goin to start new topic, how did you load those maps? I tried using UShock which works fine for many games but not Lineage2 (also not older versions). Do you have information how .unr files are parsed?

UShock shouldn't work with any other games except those it was written for. Lineage is not in it's compatibility list.

Ok. But it loads unr files. So it means he had information about structure of the unr file from somewhere to parse it. Do you know where from?

Reverse engineering, like me.
