(February 2026) Monthly WIP Screenshot Thread

This month I started to work on the building system for my game. After a crash course in current Blender version I ended up with my model for a building. The main goal was to test how construction progress could look like.

I ended up modifying the PBR shader to use vertex colors in a different way - The Green Channel defines the “Construction Height.” Each vertices has a value between 0 and 1 (set in Blender), the shader reveals the mesh part by part

The Challenge: The hardest part was the Shadows. Initially, the invisible parts of the mesh were still casting “ghost shadows” on the ground. I had to adjust shaders for both the PreShadow and PostShadow techniques to ensure the discard logic synced perfectly with the main render pass.

Here is a quick video of it in action:
