I can normal slice mesh in editor launch,but when package this project,it do not work(can not slice) anymore,I have try both shipping and development package.
Sorry for the delay.
I attempted to reproduce this using the procedural mesh slicing from the Content Examples project in 4.15.1, but it is working for me in a packaged build.
Would you try testing in 4.15.1 to see if the issue still occurs? If it still does, would you be willing to upload a small test project with your setup for me to look at internally?
