Your material package will be installed in C:\Program Files\Meitu\Sucai\Moban\Wenzi\Qita by default (I don’t know where you installed it, but I installed it here anyway)

But if you want to see the materials in Xiuxiu, you need to cut the installed materials to the location E:\Meitu\Sucai\Wenzi.

Or click Text → Import Template to import the material you just downloaded.

If you have any questions, you can go to the Xiuxiu official website, where there will be more detailed answers.
