question

In case it was a shader issue, I added proper MSFS PBR materials to the fuselage. It made no difference.

Hello Bill,

Looks like a normal interpolation artefact to me.
I don't know how the Blender and its exporter handles this but what I know is :

- we tend to have additional edges around any chamfer as shown in the DA62 wireframe below
- we use 3DS Max smoothing groups to avoid this kind of problem. Red faces below are in a different smoothing group. I think Blender equivalent would be "Edge Split".

I hope this will help you solving your issue.

Regards,
Sylvain

Shape too complex; game can't compute. Break up the mesh a bit! I fixed my aircraft this way. The other thing you can do with blender that I find quite often on the Asobo LODs is separating faces after shading smooth, and rejoining them. I can upload an example if the fix above does not work. To sum it up, the game thinks it should bend the light around the object where it's not necessary. In my personal remakes so far, I've found myself separating faces to deal with this more often than adding unnecessary tris/polygons to the model. Keep up the great work!
