crazyracing kartrider models (.1s)

[testing4562145]

i was able to extract the .rho archives using rholoader, but all of the model files are this, this is also used in airrider, but you need to change the .arb file extension to open them, some people ripped the models via hex editing, but it's a quite hard task as you can't find a tutorial that easily, i have provided samples for the karts and the tracks since they were more promising, the tracks also link the textures to theme/envirnoment/textures as there are none in the folders

there is also a post here 

 

karts

track models

track textures

also to note, the karts already have the textures in their designated folders, but some tracks have ones specifically related to them, where they can't be found in those common textures

characters are the same as karts, but have lots of textures and models for different expressions

"Yes~, the .1s format file divides the model structure into [Characters], [Cars], and [Maps], each with specific reading rules. Hexadecimal data records different types of tags related to the file. When a specific byte tag is read, it adopts the corresponding reading method. The file records the names of models and virtual objects, and you can find the corresponding model data areas from these sections. When you cannot view the corresponding ASCII code using UTF8, you should switch to UTF16, which will allow you to better locate the required data sections. (This is my research record on it from three years ago.)"

“是的~，.1s格式文件将模型结构分为【人物】、【汽车】、【地图】，每一个都有特定的读取规则。十六进制数据记录了与文件相关的不同类型的标签。当特定的字节标签读取时，采用相应的读取方式，该文件记录了模型和虚拟对象的名称，可以从这些部分找到对应的模型数据区，当使用UTF8无法查看对应的ASCII码时，应切换到。 UTF16，可以让你更好的定位到需要的数据段（这是我三年前的研究记录。）”

Hello, have you made any relevant teaching videos? I want to learn and analyze .1s files

[bobo]

No, I haven't created any tutorials for it. In fact, the only file record I can find on my computer is this image, which came from MR. Although it has been a long time, I still remember that it was a relatively simple data structure. You just need to write a script based on the data structure to import it into 3D software like Blender or Maya. The .1s file contains multiple dummies and sub-meshes, and writing a script to handle these would be very efficient. If you've never dealt with these before, I recommend starting by learning how to view data using hex. Once you've mastered that, it should only take you about 15 minutes to analyze the model (it's quite simple; you just need to follow the teaching documentation once).

不，我还没有为此创建任何教程。事实上，我在电脑上能找到的唯一文件记录就是这张图片，它来自 MR。虽然已经过去很久了，但我仍然记得那是一个比较简单的数据结构。您只需要根据数据结构编写脚本，将其导入到 Blender 或 Maya 等 3D 软件中。 .1s 文件包含多个虚拟对象和子网格体，编写脚本来处理这些将非常有效。如果您以前从未处理过这些问题，我建议您首先学习如何使用十六进制查看数据。一旦你掌握了这一点，分析模型应该只需要大约 15 分钟（这很简单；你只需要按照教学文档操作一次）。

Your reply is very useful to me. In fact, I did try to use MR to analyze the .1S file, but I couldn't find the accurate value, couldn't analyze the accurate model, and couldn't find the relevant teaching video, so I didn't succeed.

I also use HEX to analyze the data of .1s files. I can understand the basic ones, but I have no idea about .1s files.

I think your ideas are great, but I have been trying hard for a long time without success. Can you provide more detailed tips? I want to continue researching

Has it been resolved

[testing4562145]

the format is pretty basic, but nobody has gotten tracks yet besides like two people, i remember paperman got the tracks from hex editing (this came from the re-volt world discord server but it got removed) and the tool for track viewing isn't out yet
