i’ve searched through bug reports and found this: https://developer.blender.org/T63010
now i have some questions to mr @brecht.
and i’ll try to explain everything better.
i’m making game ready models, so this means, that all objects in a character should be in one mesh.
so lets suppose i’ve textured everything and now im not happy with a skin texture on a hand for example and i need to rework it.
so what was the workflow in 2.79?
i go to edit mode, with L i select the mesh i need to texture, i invert a selection, hide everything else to keep only desired mesh on a screen, go to texture paint mode, click ‘face selection masking on painting’ button and happily reworking the skin texture and you guess what, there is no black freaking wireframe!
and now the only workaround is to separate the desired mesh from an object (at least uv of a separated object stays on the same place it is on the character’s mesh), otherwise, i have to see ‘through’ this wireframe, and for some reason mr Brecht doesn’t consider this a bug.
how is that?
does this mean, that for a every single tiny fix on a texture i need to separate the desired mesh, then rework it and then join it back, and do it over and over again for every tiny piece of mesh?
i am able to take into consideration, that my workflow is wrong and mr Brecht has a ton more experience in making game models than me, so in that case i would be happy to hear what i am doing wrong.
and more over, i was so happy with all that eevee stuff, bc eevee grants access to texture something and see the final result pretty much close to the game engine.
and L0Lock said ‘If you disable overlays completelly it goes away’
and that is kinda workaround untill you realise, you are not able to switch between ‘clear’ display of a SINGLE texture (when you turn opacity to 1 in overlays) and ‘combined’ textures in the whole material.
and after baking, when you need to make some fixes by handpainting (baking is always not perfect) you are not able to do it with overlay turned off.
the only workaround here is to switch to the solid shading, which means that switching will be 2 extra actions in the workflow.
and i am suuuper curious to hear an opinion from the author of bpainter addon https://www.blendermarket.com/products/bpainter?ref=2
he said he is going to adapt his addon after 2.8 release with eevee and stuff, and i think this extra black wireframe will be a trouble for him either.
i am sorry, i just don’t know what to do with that.
