Here I'm stating all the issues/development faced before the official starting date

Scene set up

//TODO:

6th of June

worked on

• Making the CustomData_bmesh_copy_data work for the BMesh blocks to transfer color loops
  in progress 70%
   

achieved

• Understood the arguments of the function and where to find them mainly (more details will be found below)
• Written the first Not working ^_^ BMesh transfer ... which I claim that it will work for the Mesh datatypes (more details below)
• Tracked the mesh_vertex_color_add function that adds a new Vertex Color group to the mesh (which clarified many things actually)

The full story

• Answering point 1) and 3) in Achieved

I decided to track the operation of adding a new vertex color layer to figure out how those data are being stored as CustomData CD_MLOOPCOL and where to find them exactly. (noting that I knew in advance that they are being stored as Custom Data of that type)

The following picture should illustrate the tracking process (enough talking ^_^)

• Answering point 2) in Achieved

at the point of the first hint its declared Mesh* me ... I tried and used BMesh* bm and figured out that the ldata information disappeared ... which I relied one them while calling the function [CustomData_bmesh_copy_data(&bm_src->ldata, &bm_dst->ldata, &bm_src->ldata.layers[index].data, &tmp2);] that's considered the core of transferring any BMesh Custom Data

My proposed solution for now is to try executing the function now with Mesh* me_src, me_dst; instead of BMesh* bm_src, bm_dst; till I know the reason :)
