Does anyone know how to export Sims 4 into MMD?

I'm not sure where else to go for this question

I've seen this question asked before on here but no answered (lol I thought I try.)


I know umpa has achieved this and so has Malik Hatsune 

I've tried asking my MMD community but they either say 'it's a secret." Or ignore me completely

I've been trying to export my Sims 4 character from into MMD by using Blender


What I do is export the character from Sims 4 studio into blender
Then in order for it to work propperly in MMD and in PMD

I have to convert it to an X file because that's the only file it can read

So first I have to convert the sims 4 file into a OBJ file then close out then reopen it

It's completely grey...I still haven't figured out how to keep textures on it.

now if I convert the sims 4 file into a DAE file and reopen it using blender and export it as DIRECT X it's still grey
When I try to open it in MMD usually only half of her body appears

While as an OBJ file only gets an error after I convert it using Direct X


Anyway...does anyone know how to export the SIMS 4 file from Blender to MMD? (Miku miku dance.)
(Pardon my english.)
