Is there any UV unwrap tool for pixel alignment in light map?

Hi everyone! after a lot of hours spend doing UV mapping and vertex-pixel alignment… Do you know any tool to do this automatically?

I’m talking about aligning your vertex in the second UV channel, so there is no diagonal lines and align the vertexes to the pixel intersections, so you don’t have any line in between two pixels.

this is an example of what I’m talking about

this is the uvs pre-process them

and this is the result after aligning the vertex and fixing any diagonal lines

Is there any tool that you use to do this automatically? any script or something like that (I don’t care if it is for 3ds max, blender or any other program, I just want to get this process done automatically because it is incredibly time consuming)

Yes uv-unwrapping is time consuming and part of the process. There are tools out there but like everything else automatic there is no magic button to produce perfect results everytime.
