Load the correct Pipeline version

• Go to: SeamlessConverter/Renderers/

• Open the folder that matches your project (Built-in, URP, or HDRP).

• Double-click the installer/import file inside → Import.

• If you switch pipelines later, re-import the matching variant here. Pink (magenta) materials = wrong or missing variant.

Make your first material

• Create → Material (e.g., M_SeamlessTest).

• Set Shader to Seamless Converter Shader.

• Assign a non-seamless texture to Texture.

• Turn Seamless On.

• Quick tuning:

  • Style: Texture / Both / Debug

  • Focus: smoothness between hex cells

  • Rotate / Zoom: per-cell variation to break repetition

  • (Optional) Add Normal map and adjust Strength.

Try the demo scenes

Open SeamlessConverter/Scenes/ → Plane, Triplanar, Sphere to see ready setups.

Common fixes

• Magenta materials: Re-import the right variant from Renderers/.

• URP/HDRP not rendering: Ensure a valid Pipeline Asset is assigned in Project Settings.
