Stardew Valley 3D mod brings VR support and full third dimension to the farming sim

A modder named kittycatcasey is building The Third Dimension, a Stardew Valley mod that converts the beloved 2D farming sim into a fully navigable 3D space — and it already has working VR functionality.

The mod is currently a self-described "decent proof of concept," but it's functional enough to walk around your farmhouse, talk to your spouse, check the weather, and harvest crops — all in three dimensions. Right now most objects outside the terrain are rendered as billboarded sprites rather than true 3D models, which gives the whole thing an uncanny quality, but kittycatcasey says the plan is to replace everything with unique 3D models over time. The VR side of things goes beyond just looking around — you can physically hold individual tools and swing an axe to chop trees. The modder also confirmed no AI is involved in the project's development.

Stardew Valley, developed solo by ConcernedApe and released in 2016, has one of the most active modding communities in PC gaming. The game's open structure and dedicated modding tools have produced thousands of mods over the years, but a full 3D conversion is a genuinely unusual undertaking — most mods stick to content additions, balance tweaks, or visual overhauls within the existing 2D framework. Pulling the game's pre-existing sprite assets and mapping them onto a 3D plane, rather than rebuilding everything from scratch, is the approach kittycatcasey is taking, which explains both the speed of progress and the occasional missing wall section.

The mod doesn't have a release date yet — it's still in early development — but a proof-of-concept video is already up on YouTube showing the whole thing in motion. Given the VR support is already functional at this stage, there's clearly more ambition here than a quick tech demo.
