First screenshot view will be from Blender. This is to check if you are okay with how the structure of the mesh looks. ONLY the structure during this process, NOT textures. You can request needed changes here. The size of a particular piece or form. and placements. Throughout the whole process I will be going back and forth.

I will be uploading the mesh into the Beta Grid. This is a place where creators can request to log into by Second Life to test their mesh and scripts on a sandbox for free without paying Lindens. I will be sending screenshots from there on how the mesh looks inworld. Please understand that the size of the mesh can be changed by you.. You can only ask to change the textures or placement of something on the mesh here. 

This is where I will be texturing the mesh. Here is where I will ask if you are okay with the color placement for the texture of the mesh. Please be aware that the texture in Substance Painter will not shine or look exactly like it will inworld. 

This is where I will upload the mesh into the actual SL grid. This will be the last screenshot being sent. After this step I will be sending the mesh to you. Check if it copy, mod and trans for you. Sometimes SL change the permission during transfer.
