HARDTOPnet Minecraft page
HARDTOPnet designs and develops texture packs and tools for Minecraft
for the Java, Bedrock, and Pocket editions of Minecraft.
Our packs have started gathering widespread recognition thanks to their exhaustive LabPBR support, attention to detail, and great balance between photographic textures, 3D modelling, and procedural generation.
The Vanillaccurate and Realaccurate packs have been praised by lots of Youtubers like AsianHalfSquat, FernFox or 1Tech; and is also the pack Sonic Ether recommends for his SEUS PTGI HRR 2.1 shader.
Whichever style suits you best, HARDTOPnet has a pack that might fill the bill.
HARDTOPnet also designs tools and scripts for Minecraft. The SkoMC toolbox is a program that's intended for resourcepack enthusiasts or professionals to help them author and convert their packs to various formats, or perform checks or apply various adjustments on whole packs at once.

Vanillaccurate

Vanillaccurate is a pixel-vanilla-styled pack but with lots of details and full LabPBR support, with resolutions up to 512x and even AI upscaled packs up to 2K (to be used with PiXXL).
It's 1.17 complete (blocks and tile entities). It also exists in Bedrock RTX/DXR flavor!
PiXXL Accurate

PiXXL Accurate (or PiXXL for short) is the sequel to Vanillaccurate. It offers blocks from newer versions that Vanillaccurate doesn't cover (post 1.17), this time up to 2K resolution.
Realaccurate

Realaccurate is a similar pack that doesn't have the "pixel" patterns, it's more realistic while keeping very close to the vanilla theme. It has textures up to 2K as well.
ToonAccurate

ToonAccurate is the third pack in the HARDTOPnet *accurate lineup (it was developed before PiXXL), and features cartoon-esque stylized blocks with lots of details still, and some features are baked it, making it even suitable for shader-less environments. It has textures up to 512x and is planned for release on Bedrock as well.
