Tesselated snow footprint via Blueprint

Greetings everyone!

Ive done a snow footprint system, using this tutor: https://www.youtube.com/watch?v=oKQLPNIIoOI This is what i want, but there is some issue. As Im understand, only 20 decals spawns using linetrace so 20 tesselated footholes has been created.
Can anyone explain me, please, how to spawn a tesselated foothole each time, the linetrace reaches terrain and not only 20 but more?
I will be very glad for any answer. Thanks a lot and sorry for my English.
