Can I just get some quick information on the format of the geometry of the levels? I only need triangles (vertex and index buffers), no paths, objects, AI, etc.

Using Temple as an example, this is what I have figured out (followed by what I need to know):

I open Ump_setupdishZ.bin and the format is not immediately clear. I can’t find room locations even, nor paths to files, etc. Somehow when I load this file the editor knows how to find the vertices for rendering, though.

So I move on.

I look in RoomStarts\ and I open templeRoomData.txt. Pretty self-explanatory. When I load a room I am going to have to offset it by these locations.
I go to WallData\ and I find Ump_setupdishZ\.
Here I can find 69D3D0.bin and the rest of the files referenced by templeRoomData.txt. 16 bytes per vertex. No problem. I also know these vertices. I know what the first few vertices in Temple are supposed to be, and 69D3D0.bin has the first few vertices.



So I do know where some of the vertex data is, and this is the exact data I need (position, UV, color).

But I am left with some questions looking at this data.

69D3D0.bin is a vertex pool (or a vertex buffer). I know that the first 3 vertices here create the first triangle in Temple, but the 4th vertex here isn’t the first vertex in the next triangle, it’s the last.
I know that there is supposed to be an index buffer with indices: 0 1 2 0 2 3 4 5 6 4 6 7 7 6 8 7 8 9 9 8 10 9 10 11 12 13 14…

Question #1: Where are the index buffers?

Then I notice that templeRoomData.txt lists 69FBE8.bin as the final set of vertices for the rooms, but I notice that 691D74.bin is a vertex file and it isn’t listed in templeRoomData.txt.
Question #2:: Is templeRoomData.txt incomplete or do I not need the unlisted .bin files to render a complete level? If it is incomplete, how do I know which .bin files are vertex data?


Thank you!

Thank you, though as useful as those may be at some point, only one of those documents has the word “vertex� in it, and it’s display lists. I’ve already found and decoded 90% of the data I need. I’m just looking for the index buffers and possibly missing data not listed in templeRoomData.txt.

Those documents seem to be dealing with the data in the game, whereas I am working with files in the GoldeneyeSetupEditorV2.exe folder (and subfolder). These files are already uncompressed and sorted into several files. I am asking about that.

I was not aware that the temple wall data folder has some extra data not listed in the roomdata file. I don't mess with these files at all so someone else more familiar with them will need to reply, or you can ask on the N64Vault discord for replies from people who are not here.

V2? Little out of date, don't you think?

I seem to recall the old builds came with two variations of the background data (bg and bgfull?), but that is going back quite a few years now. Are you referring to the BG data that sets the whole file, with the offsets to each 1172 compressed file, the room centers, portals, and special visibility?

[L. Spiro]

I thought I had a newer version but it seems I didn’t copy that one to this new laptop when I moved back to Japan. Let me just get version 4 and peruse the files a bit…


I’ve caught myself up to where I was before. Things are just in in different folders.

If the BGDataFull\ files are what gives structure to everything then I am likely to need them, I guess. If there is no other way to access all of the vertices in a level directly, such as via RoomStarts\.
Is the data in RoomStarts\ incomplete?


Starting where the editor starts, let’s say I load Ump_setupdishZ.set. How do I know which BGDataFull\ file to load? I’m guessing there is no way around parsing the .SET file, although I need only parse it just enough to locate its associated BGDataFull\ file, I hope.

Once I find the associated BGDataFull\ file, then I guess I need to parse that. But just enough to give me the vertex data (which I know to be in WallData\ and I know how to parse), index buffers (which I can’t locate at the moment), and room offsets (which I know can be found in RoomStarts\, but I suspect there is a copy of that data inside a .BIN file that I should be using instead).

If you want the vertices and display lists extracted from a background file, the quickest method would be to open a level in Visual, switch to room mode, then right click and choose the top option. Export room positions to text file. Save the .txt file to a new folder, and you will also get the room files with it. Portals can be exported under portals mode, as can any special visibility used by that map.

[L. Spiro]

Well, that exported all of the same .BIN files that were originally listed in RoomStarts\.

Okay! I think I can work with this! Thank you!

Is there something special I need to get or do to load Perfect Dark, Jet Force Gemini, etc., levels?

You need to switch the editor to the respective game

If you can create a geometry mesh tool that can replicate exact layouts from the GE equivalents you could literally exact PORT GE levels into any game format yes?

I would love to do this with source engine more accurately using models ripped from N64 GE geometry

The set file (setup) has no knowlage of the BG file.

Since you have the decompressed assets the vertex stuff is
a vertex list
a display list (primary or secondary)

the vertex list is a list of all vertices for each room (not buffer)

the display list then loads the buffer with the G_VTX command (04 I think) which places n vertices into buffer from index i.

so, perhaps the reason you dont see the 2nd triangle is because the triangle addresses a different vertex
eg
gsSP4Triangles(0,1,2,8,12,10,2,1,3,7,8,9);

or it happens on another buffer fill.

Yep!




















The textures have had their addressing modes baked in, so they will look correct in any game engine, even if that engine doesn’t support all of the texture-addressing modes these games used on Nintendo 64 (for example, Blender doesn’t allow the U and V to have different addressing modes).

Every detail is accurate and preserved so these are basically ready to go from here into any game engine whose file format is known.
In a lot of cases, that will involve generating solids out of a triangle soup, so it doesn’t mean that exporting to all games will be easy, but just that it is easier than ever before.
