I did some searching around the internet for a program that would allow me to update the texture of a mesh while I am painting it in an external paint studio. I found a thing called "Verse". Not sure how to use it and I am not here asking how to use it as it has it's own discussion forums, I am here to ask if anyone has spotted any other programs that will allow for what the title suggests. preferably something not to high in cost or free.
Here is the link to "Verse"
