Irregular lighting issue

News & General Discussion
1

Hi,

I’m having an issue upon import to Unity (2019.3.15f1) I use 3ds Max to Model and texture. I’ve tried everything I can think to cure this problem but i cannot fix it. To list but a few:

Tried flipping and unifying normals in max

Tried resetting X form

Tried flipping individual parts of my UVW map

Tried different lighting setups

Tried Resetting UV channels

Tried mapping to different channels

I’ve tried UV mapping the model instead of Unwrapping. I did manage to solve an issue i had with a Mapped “Plane” my doing this, But most models with a third dimension seem to do it, in places.

I’ve tried different HDRI sky maps

If anyone can help with what maybe wrong i would really appreciate it!

Cheers

James

It looks like you’ve got the curved part set to Smooth shading, and the flat part it connects to set to Flat shading. In my modelling, I find that often looks bad along the edge connecting the two faces.

Have you tried just setting the smoothing on the bug flat part to smooth?

In Blender, there’s an angle-limited auto-smoothing option which I usually use for this kind of thing.

Hi,

Thanks very much for replying.

I’m not too Au fait with Blender. I’m guessing it’s a similar principle to smoothing groups in 3DS max? I’ll have a play with the smoothing groups of the affected meshes and see what results I get.
Thanks again!

Try “normal angle” in the model import settings inside unity

That’s almost certainly a baking issue.

just rebake the scene.

As a backup plan, you might want to raise the quality of the baking. Hopefully, that also solves that problem.
