hi dsk (Prabhu) !
Are u referring to Fascia Coupled with Fat Technique ? After the release of 1.4 ZivaVfx where rest scale, surface tension and pressure attribute added in Tissue, one can eliminate fascia step and directly use the above attribute in tissue i.e Fat object.
Please Check this tutorial in Resources tab, where @andy_vs has explained the process in detail.
Please note, to get/Model the inner part of Fat zCloth is still being used.
