Hi! Thanks for trying Taffy 3D 🙂
Blank maps are usually caused by one of two things. Let's start with the most common:
**1. UVs on the low-poly mesh**
Make sure your low-poly has a proper UV unwrap before baking. If the mesh has no UVs (or only auto-generated ones), the baker has nowhere to write the result and outputs a blank map.
**2. Scale mismatch between high-poly and low-poly**
This is very important: both meshes need to be exported at the same scale. Taffy 3D has some internal protection against scale differences, but it is not perfect — if the high-poly and low-poly are at very different scales, the ray projection may miss entirely and produce a blank result.
A good rule of thumb before exporting:
- Apply scale on both meshes (in Blender: Ctrl+A → Apply Scale)
- Make sure both are roughly aligned in world space
- UV unwrap the low-poly with no overlapping islands
Could you let me know which software you are exporting from? That will help narrow it down further.
And yes, you can open issues right here on this page — would love to get this working for you! 🍬
