MESH format ".bm" Rakion, file addded

[moonpaladin]

Hello I was searching for weeks and did not find a way to open the ".bm" file of Rakion, it contains the 3d model, maybe someone knows how to open it or could give me some advice what I could do, it would be very helpful . Thanks in advance.

Thanks alot for this! I was searching a lot. By the way where u got the values of 12, 103c, 99, 8 and also the 41 XD, I'm trying to find how do you get that values with the tutorial but don't understand how you get these values. Thanks also!

1st of all: learn how to detect floats. If you can't you're lost. As simple as that.

floats consists of 4 bytes (half floats of two).

You need to gain experience by checking some dozens of simple examples in the forum where hex2obj was used.
And you need to learn some basics.

Understand how to get 15ac, 408 and 41, 170 (the simple part).

Once you succeeded I can explain FVFsize: 12, and 103c and 8 (harder part).

I already know how to get the value 41 and the others values! now need the vertex block values only!. Thanks for answer!

[shakotay2]

8 is 2 floats for texture coords tx, ty.

"99" is a flag only, that tells you: uvs are in a separate uvb block.
Start address of that block= 0x41 + size of vertexblock+ size of normals block // 0x41 + vertexcount x (12+12) = 0x1031 // 12 is decimal, 3x4 floats
+ Dword_string_length + string_length // 4 + 7
= 0x103C

I apologize, I have doubts, how to know where to find the values of:
size of vertexblock
size of normals block
Dword_string_length
string_length

Really thanks for taking the time to answer me, I'm learning

[moonpaladin]

Thanks aloot!!!

You*re learning very fast! Cool!

Dword_(for)_string_length: size of DWORD is 4 (value is 7, the string length)
string_length (of "Texture") is 7

size of vertexblock: vertex_count x 12
size of normals block: vertex_count x 12

since size of vertices is 3 floats (3x 4 bytes)
size of normals is 3 floats (3x 4 bytes)

Thank you for clarifying all my doubts

Was wondering if you created a converter for bm to obj or should i start learning what you've learnt

[Karpati]

Do you have an unpacker for the Rakion.xfs file?

I did a crappy Noesis script - I'll post it when it works properly. It would be good to get a few examples of models with their textures to do some proper testing.
