I believe you using it in a predominantly white VS made it way more obvious to notice (this flaw) compare to a more colorful/crowded VS

The UV maps on their own are correct , is when combining them with other layers (mostly a transparent one) in image editor the result is creating the issue



Yes coincidently the VS that I used has a great contrast with it. Still, thanks a lot everyone for the help and effort in troubleshooting!

Yes, I've also exported UV maps from Blender (recent example on my website here: Virtual Studio Project with Blender & vMix). The large semi-circular cyclo in that project didn't show any artefacts, but the floor was deliberately made darker near the edges to hide any potential problems. I have sometimes encountered glitchy edges with Blender, but mostly on nearly horizontal straight edges. My workaround is to scale the UV colour texture a couple of pixels outside the object's UV map in Blender, which seems to achieve the same result as cropping a couple of pixels. Or, of course, place a layer in front of the UV map - I've noticed that quite a few sets with virtual screens include a frame on a layer that sits in front of them, which conveniently hides any ugly edges!

First make sure you create your UVMap in 4K and over size it by a few pixels so the edge issue isn't a problem. Or feather it if allowed.

In photoshop make sure your set to image mode 16bit per channel before working with your uvmap and again make sure its at least 3840x2160. Even if your working in a 1080 or 720 workflow. This insures the sharpness when manipulating the UV map if needed.

when resizing or doing anything make sure you are your only resampling when downsizing.

once you are done always go to File and select the "Save As Copy" option. not the Save or Save as or the Export. Never use Export to PNG because it will always use a 8bit channel. The "Save As Copy" is the only way you can create true 64bit PNG files and that's what you need to remove a lot of your issues with quality and what not. Otherwise Photoshop will save it or export it as a 24bit PNG or 32. When you hit the "Save As Copy" just go down and select the PNG option and a dialog will pop-up and just hit enter.

Not you can use the Save As but only if your image has a single layer. so i just use save as copy and it doesn't matter

What if you have to resize, crop, modify shape of the UVmap into a full sized frame to something that fits within the VS layout?
