Ayrton Orio Posted March 18, 2019 Share Posted March 18, 2019 I have been using the same program as the rescale of FF7 (https://venturebeat.com/2019/01/28/final-fantasy-vii-hd-graphics-mod-makes-backgrounds-less-blurry-with-machine-learning/) to rescale some project zomboid sprites. 1 - this is probably silly to start with as many sprites probably stem from a larger artwork anyway 2 - This is essentially against the original art direction 3 - Sometimes it doesn't look great, sometimes it looks amazing in my opinion 4 - Topaz is not trained specifically for this task (pixel art to ... HR artwork i guess?) Link to comment Share on other sites More sharing options...
You've Got Red On You Posted March 18, 2019 Share Posted March 18, 2019 Gives the items a more watercolour-esque look to them, I like it Link to comment Share on other sites More sharing options...
Viperel Posted March 19, 2019 Share Posted March 19, 2019 They seem to have a good look, especially the larger objects. Haven't thought of using it on the game, I'll give it a try myself and see what results i get. Thank you for the inspiration! Edit: Added some photos enlarged by 4x (with Topaz A.I Gigapixel) Link to comment Share on other sites More sharing options...

I guess doing a mock up of a small interior scene (at 100%) in PZ would be interesting, but I'm crumbling under work at the moment... Link to comment Share on other sites More sharing options...

I was wondering if you could show aversion of the zoom at 400%? (so you get the pixel art unaltered on one side and a Topaz version at 100% on the other side? you see what i mean?

Ayrton Orio Posted March 19, 2019 Author Share Posted March 19, 2019 If you train a neural network to do the opposite, from HR artwork to pixel art you could get a pretty neat "pixel art" filter. dataset should be restricted to isometric art which could probably be detected through AI, I don't think the data is what is lacking anyway Link to comment Share on other sites More sharing options...
BoogieMan Posted March 19, 2019 Share Posted March 19, 2019 Huh. That's pretty cool. In most of them I think it looks nicer. I like the clean lines, and that radio image was massively improved. Link to comment Share on other sites More sharing options...

I'm thinking about turning this proof of concept into a texture mod, but first i have to read up on how modding works for this game, as i have no clue how to reinsert the modified (larger) textures as of now. It's still an improvement to upscale and then reduce them to their original size so i can use the PZ Unpacker to remake the .pack easily but i was hoping for a 2x size in textures at least (highly lossless compression applied of course) Link to comment Share on other sites More sharing options...
Ayrton Orio Posted March 20, 2019 Author Share Posted March 20, 2019 I'm not 100% sure, but it might get quite difficult to double or quadruple the texture size, it's not a matter of just changing the source tiles. Link to comment Share on other sites More sharing options...

Noticed that the hard way, the game will not accept larger textures than the ones already present. I tried making an up-scaled version then reduce it to the default size, they look better (especially the wood/metal furniture) but the texture edges don't blend in with each other. Not sure how to fix it for now and i don't have that much time to invest into it. Link to comment Share on other sites More sharing options...
Ayrton Orio Posted March 20, 2019 Author Share Posted March 20, 2019 actually i tried the upscale-->downscale method (bilinear smoother, sharper and nearest neighbour) and all it does is that the original model loses detail, on all accounts i thought the original artwork was better. As for tile size, yes they are hard coded, and there might be many other things that relies on the tiles being a given size. I think it would be quite a hefty mod to make. Lastly, the blending in between tiles doesn't work because you used anti aliasing in the making of your tiles which makes seams messy. If you check at the orignal tiles you will see that every tile is pixel perfect, that's why the seams are invisibile. Link to comment Share on other sites More sharing options...

The upscale helps a little with edges and wood grain as you can see in this comparison left original / right upscale + downscale Link to comment Share on other sites More sharing options...
Ayrton Orio Posted March 20, 2019 Author Share Posted March 20, 2019 I don't think it's a "just a mod" thing, if someone wants to do it there is quite a few obstacles to overcome: - know the PZ engine inside out to be able to adress all the bugs that will for sure occur - painstakingly long task of resizing (Topaz), cleaning up & fixing, transparency mask (i think topaz doesn't tapke in account transparency), then redifining tile size for all sprite (a lot of handwork i think) - keeping up to date with PZ development as new sprites and textures are being added i think it's a lot of work and maybe it's more a thing of "let's wait until the game is finished and stable development wise" and then let's plan what to do then. Also, you never know but the development team might revamp the way sprites are handled and make things considerably easier in the future. Link to comment Share on other sites More sharing options...

It's because of how Topaz works: to give you an example I was recently working on a resizing of an actual photography where the main subject was a man with a 5'o clock shave (grey, one day after you shaved) and the upscaled version looked very neat and detailed except for the beard shade that disappeared. I think the same thing is happening with the grim on the furniture tiles. Link to comment Share on other sites More sharing options...
