Venetica Mega Texture Mod
There is a huge texture mod, made after original 2009 release,
12 GB unpacked, 5 GB original files
It c an be reduced to 4 GB, with an AIO 7-Zip repack, as a *.7Z Archive with maximum compression settings.

Venetica Mega Texture Mod - Mod DB

Note:
Of the3,000 textures in the mod, just under 2,000, are identical to the game contents on GOG (hash checked).
Even if only that 1,000+ are actually modded, it's still a large number.
It's also possible, but unlikely, that the identical ones were actually added to the game with the Gold Edition update.

Skimpy Addon
The "Venetica Slipless Dress HD" file, was uploaded just after the Gold Edition released on Steam,
Over 5 years after the Mega Mod released. So not really part of the original mod.
It''s also a semi-nude skimpy (Cut Out Armour) type mod.
Some transparent dresses, are (only slightly) more tastefully done, but still skimpy mods.

Thanks!

Mega Mod is 1k, like Vanilla Gold Edition, but with sharpen filter added.
The Hair mods in the Skimpy file are worth a look, even if the skimpy armour is not your thing.

I've made a few 2k variants of Scarlett's clothes/armour from Vanilla files, using GIMP, and added several hair colours upscaling the meagre 256 pixel vanilla hair.

The Complete Venetica Walkthrough - Forum - GOG

Hello, UhuruNUru - Today I finally popped my cherry by commenting on Gog, and now I'm making amends.

Thank you for providing this wonderful texture pack. I didn't use the hair or extra armor stuff, just the Mega Mod and the help guides. These were just great, although I wasn't aware how great until about halfway through the game when I went looking for a Youtube solution to something. Then I quickly searched for ordinary HD PC gameplay footage with all the video bells and whistles turned on, and my game looked vastly better then they did. So a very belated thank you, friend.

And for anyone interested in this, be sure to use the 4GB patch (on Venetica's EXE file) before throwing additional textures at it. That particular memory "patch" is mentioned elsewhere in this forum.

Thank's again, UhuruNUru.

Please excuse the necromancy. Does anybody know if there is a clothes mod that is a bit more revealing than vanilla, but less tasteless than the skimpy addon mentioned in the OP?

Hmmm, I also tried the Mega mod and all I found is what the author of the mod already said, that he/she only sharpened the textures and that's it. In my humble opinion, these textures do not look good in the game because the sharpening artifacts do not work in favor of the aesthetic appearance. But anyway, that's just my two cents...
