Some problems related to the MatrixCityPlugin

[SehunKing]

阅读论文后感觉MatrixCity是个非常值得一试的插件，但我在使用过程中发现了一些bug和问题，在我的两台电脑上都能稳定复现：

1. pipeline中的渲染部分代码被注释，为什么？
2. utils_sequencer main()函数中的level变量，其中Maps在实际project目录中为Map
3. 添加MatrixCity插件后，project第一次启动会编译7k多个着色器，进入project后纹理无法正常显示，提示正在准备2w多个着色器，且在城市示例中的速度无法接受
4. 新建简单project做测试，修复1和2两个问题，并等待着色器编译结束后可以正常渲染得到一些图像，但在城市示例中运行run_cmd_async会不断跳弹窗提示sequnces已存在，无法正常渲染

Hi, did you render images successfully? I uncommented the codes of render sequence, but got below error messages:

@yzslab I have encountered the same problem, maybe you can do the second point as I mentioned above to solve that AttributeError. But there will still be other problems.

[yzslab]

With render sequence block commenting out, the UE will exits immediately after project being loaded. Is this expected behaviour?

Thanks, I changed it from Maps to Map, but didn't solve this problem.

阅读论文后感觉MatrixCity是个非常值得一试的插件，但我在使用过程中发现了一些bug和问题，在我的两台电脑上都能稳定复现：

1. pipeline中的渲染部分代码被注释，为什么？
2. utils_sequencer main()函数中的level变量，其中Maps在实际project目录中为Map
3. 添加MatrixCity插件后，project第一次启动会编译7k多个着色器，进入project后纹理无法正常显示，提示正在准备2w多个着色器，且在城市示例中的速度无法接受
4. 新建简单project做测试，修复1和2两个问题，并等待着色器编译结束后可以正常渲染得到一些图像，但在城市示例中运行run_cmd_async会不断跳弹窗提示sequnces已存在，无法正常渲染

I have released all the documentations and I think this will solve most of your problems. For 3, could you give me some examples and you device information.

For problem2, thanks for your comment, I will change this typo.

For problem 4, you should delete duplicate assets manually. Our plugin cannot automatically override.

I have released all my documentations and you can refer to them. We use two steps to get the final results: 1. generate the camera trajectory sequence; 2. manually render images in the City Sample project for higher efficiency and flexibly control the environmental settings.

This means you have already created the sequence "aerial_train". Then you can render this sequence manually in the City Sample Project following Render-Data

Thanks, I followed the latest documentations, and it works fine now! Except it takes almost 2 hours to compile the shaders.

Hi, I encounter similar issue. The log shows I successfully created a sequence, but I can't find where the sequence is and UE just crashed and restarted back and forth. Could you please help me resolve the issue? Thank you

With render sequence block commenting out, the UE will exits immediately after project being loaded. Is this expected behaviour?

This means you have already created the sequence "aerial_train". Then you can render this sequence manually in the City Sample Project following Render-Data

Thanks, I followed the latest documentations, and it works fine now! Except it takes almost 2 hours to compile the shaders.

It's normal for the first rendering in City Sample to take such a long time. It will be faster afterwards, as the shaders won't need to be calculated again.

Hi, I encounter similar issue. The log shows I successfully created a sequence, but I can't find where the sequence is and UE just crashed and restarted back and forth. Could you please help me resolve the issue? Thank you

Please reader this part https://github.com/city-super/MatrixCity/blob/main/MatrixCityPlugin/docs/Generate-Trajectory.md#run-from-python. Created Sequence: /Game/Sequences/aerial_train shows you have successfully generated the sequence, which is saved in [Your project]/Content/Sequences. Besides, we do not recommend using City Sample to create sequence because this project is too large. Maybe you can create a new empty UE project to create trajectory following our guidance Generate-Trajectory. Then you can manually render this trajectory following our guidance Render-Data.

Hi, every times finish rendering, I get below error messages:

If you can successfully render the images, this information is not important.

Thanks, all images rendered successfully.

I also find that I can just get sequence asset in other small project to avoid shader compiling time, but I want to know the purpose of compling shaders, it seems that shaders are irrelevant to rendering images, and are even less irrelevant to sequence

I also find that I can just get sequence asset in other small project to avoid shader compiling time, but I want to know the purpose of compling shaders, it seems that shaders are irrelevant to rendering images, and are even less irrelevant to sequence

This is inevitable for UE project.

But the UE project don't need to compling shader when I first creat it, only when I put MatrixCityPlugin in it

I am not sure this is why. I think this is a UE mechanism, not caused by our MatrixCityPlugin. If I don't use the project for a while, it sometimes needs to compile the shader before using Movie Render Queue(a UE built-in plugin) to render images without containing our MatrixCityPlugin in the UE project. Maybe you can find a more efficient way. Welcome to submit a pull request.
