.tm filesize with massive increase

hi,

my TM filesize was 1,2 GB . i imported some more small objects with 100 frame animations in .glb format. i made one individual decal that i instance copied some times . i deleted some painted terrain geometry. then i had 3.2 gb of filesize …

i reduced double materials and deleted the not used ones. i also tried to delete no more used , empty import links… still 3.2 GB filesize.

i deleted the animated objects sometimes, also their “empty” import links,BUT i have the feeling that data still is hanging in twinmotion and exploding the filesize…

3.2GB filesize:---------1.2 GB filesize:

38,6 M TRI-------------46,4 M TRI

3,8 GB TEX-------------1,5 GB TEX

3,9 GB MESH-----------4,4 GB MESH

8776 OBJ---------------9090 OBJ

415 MAT-----------------563 MAT

i search for the massive explosion of texture size, but cannot be the explanation for the filesize ???

i have no further idea…

thanks for help!

PS: i have much textures shown in statistics-textures that when i click them show on the right properties side " no mesh is using this material " the material is seen in “materials” , shows used from 1 object with the solo tick and is not deletable !!!

this is in my opinion a heavy bug !!
