QUESTION Color issues when opening in ksEditor and Assetto corsa.

[monkichi]

Hello everyone. There was a color problem when creating the tracks.

No symptoms appear with modeling software.（use Blender 2.8）
But ksEditor and Assetto corsa show symptoms.
This symptom. I will show you the production procedure.

（Symptoms are summarized in the video）

Even if a simple square pole is placed, the color will be partially discolored.

what is wrong? How can I solve it?

probably double vertices and normals not set correctly

in blender in edit mode, go Mesh->Clean Up->Merge by Distance (use 0.00001 or smaller)

after that, go Mesh->Normals->Set from Faces

Thank you for the advice.
Vertex merging is already complete.
So I tried the following.

Mesh->Normals->Set from Faces
However, the results have changed, but have not been fundamentally resolved.



The top of the photo is "Set from Faces".

try this too:
Mesh->Normals->Average->Face Area

 

[monkichi]

Mesh-> Normals-> Average-> Face Area
I actually tried it.But things didn't change as expected.So I tried some items in the same menu.

Mesh-> Normals-> Point to Target , merge , Split ,Average…
Most of them failed, but only the following worked.

Mesh-> Normals-> Rotate...
When I typed 90 here, for some reason the discomfort was gone.
I tried other parts in this way.

However, this did not work for some parts.
I understand from change. The cause was normal.
