UV Mapping not Perfect #81

Closed heare2code closed 6 months ago

heare2code commented 6 months ago

Whenever I use this plugin, everything seems to shift ever so slightly. This becomes a problem when models have their UV maps set up so perfectly that these shifts could throw everything off. Examples: image image image image image image Not sure if this is a problem with my model (considering ripped Nintendo models tend to fuck people over) or if it's this plugin doing something. I tried changing all the properties and none of them fix or reduce this effect. I can supply the model if needed.

This issue can occur when textures are too small. The UVs scale down by 1 pixel, ensuring that neighboring textures do not encroach on them. To avoid this, you can manually remove the + 2 from the margin and the 1 + from the border_margin in this file: https://github.com/Grim-es/material-combiner-addon/blob/55a235dcd93455994aec1226bbbfd78092ff6463/operators/combiner/combiner_ops.py#L339

I tried this and it worked, thanks! Maybe you should put this somewhere in case someone else has this issue, like in the read me or as a setting in the plugin.
