The problem seems to be quite "entropic"
I decomposed the whole scene to find the problem and isolated it. However, the isolated file still hast 70mb size.
I figured out that i can avoid the error by not having a glass material with 'Blender Voronoi Texture' and an Opacity Image Map for some other asset in the scene.
I will keep on reducing the scenario until i can post a small example scene.

Thanks
