maybe backfaces or bad normals?
#Blender Baking

in the UV editor select top-left-most box, and the third option (selecting faces)
then go into edit mode in the scene, select entire mesh, and click one of the triangles on the UV view
it'll highlight the triangle in the scene, which may give you a hint why they appear there in the first place

this might be due to overlapping faces ,
select the problematic triangle and move it away from model if there's another triangle on the same spot , that's the cause
void idol
share the model if possible will take a look
void idol
model looks fine
there's two uv maps
but i didn't get the black triangles issue, it bakes to both uv's without any problems
void idol
will check , blend1 file is just a backup version created by blender , you can ignore those
the problem
- you have hidden the other models in the viewport but they are still enabled for rendering ,
- when you bake this entrance model from "Joined" collection , all the hidden models are also contributing to the lighting
- since the "House" collection also has the same model they perfectly overlap & it's giving you artifacts
completely disable the collection to be safe
