Fail to export model to moc3 file

Hello everyone, I am new to live2d and just want to export my model for runtime. However, I encountered a problem during the process.

After I clicked the “export” button, it pops up a small "exporting" window, however the progress bar is 0% no matter how long I wait, and the whole application freeze out that I need to terminate the application using task manager. My file is quite large such that it is 1gb, so I tried to reduce texture atlas size, delete unused parts and reduce extended interpolation but still cannot succeed. After I restart the application, the log doesn’t show any error message and my model file does not contain any repeat parameters.

May I ask is there any solution for my problem? Also, during rigging, I copied and reflected some symmetrical parts to another side for convenience. For example, I finished rigging the left eye of the model, then I will just copy the left eye and its child object and reflect to become a finished right eye. However, the texture atlas only shows the left eye but not also the copied right eye, may I ask is it related to the failure of exporting?

Attached is the freezing out screenshot, happy to provide more information if needed. hope to hearing back soon as I do not want to start over:(

  • Hi ookubo, the problem is solved as I deleted some unused layers and psd files on project section, I wondered those excessive layers are the main reason to make the application crash during exporting. Thank you for reaching me out anyway

  • @Gagalili Yes roughly that is the reason, but also because you run out of memory when you have a lot of them! and it is why it doens't let you render c:
