TyVAT Exporting Data Channel 3 Issue

[Evelyn_GroundShatter]

I've been having an issue with exporting on data channel 3 in the TyVAT modifier. I'm trying to use data channel 2 for lightmap UVs in Unity for light bakes. Exporting on data channel 2 works fine, but exporting on data channel 3 breaks the mesh.

I've attached a video that demonstrates what's happening, and the Max file that I'm using.

Any help would be greatly appreciated, thanks very much.

Did you adjust the shader to account for the map channel change? Default assumes tyVAT data will start at map channel 2 (texcoord2), but if you're storing lightmap data in map channel 2, then you'll need to adjust the shader to start at map channel 3 (texcoord3).
