If he doesn't want to maintain it that's up to him. It's a phenomenal mod and it wouldn't be difficult for another modder to update it. There shouldn't be too many issues between old and new besides fixing some graphic size properties, and probably moving the spinal weapon barrels by a few pixels.

Maybe you can persude him with dollars? But it's not up to us what another dev does or doesn't do with their free time.

Please don't integrate it! Oscar's work is very nice, but I (and I'm sure many people) love original graphics.

I think Oskar's work is outstanding. Obviously can't get better than Vanilla, and he was asking me most of the time what I thought of each piece, preserving the original intent with a higher resolution and clarity. So I really like the work he did.

The only downsides are that certain sprites became almost indistinguishable from one another at a glance, such as the shield generators, life support, and afterlife caskets, all of which lack clearly identifiable silhouettes and coloration, which is a design oops and product of the attention to standardization. The weapons are better fit for vanilla expanded and also lose their easily identifiable YRGB grammar. Shuttles also look like no man's sky, but the inclusion of directional sprites is welcome. (I just have no patience for that repetitive perspective task as a 3D artist lol.)

But otherwise the VTESOS textures are great, and if this were an official product Oskar's redux would probably be the official art. I'd not integrate them as many have said they prefer SOS looking like SOS.

It's a bummer he intends to retire that mod. His work tho. His rules.
