gradient structure

[yiyuxingchen]

Hello,everyone!
I want to make such a structure, the upper layer is equiaxed grains, and the lower layer is equiaxed grains plus fibrous structure.I try to generate multiscale tessellations, but the interface between 1-scale grains is not a normal grain boundary, and I don't know how to generate a structure with a mixture of equiaxed grains and fibrous structures.
Thanks in advance.

$ neper -T -n 3::1000 -id 1::1 -morphooptiini "coo:file(coo1),weight:0" -morpho "gg::msfile(morpho_msfile3)" -o 3 -statseed x,y,z,w
$ neper -V 3.tess -datacellcol ori -cameraangle 12 -imagesize 600:600 -print img3
coo1:
0.50 0.50 0.15
0.50 0.50 0.50
0.50 0.50 0.85
morpho_msfile3:
1 diameq:lognormal(2,0.35),1-sphericity:lognormal(0.145,0.03)
2 diameq:lognormal(1,0.35),1-sphericity:lognormal(0.145,0.03),aspratio(2,2,0.5)
3 diameq:lognormal(1,0.35),1-sphericity:lognormal(0.145,0.03)

It's interesting. But I don't believe the current version of Neper can do this.

Do you solve the problem of how to build gradient crystal model with neper？
