Hi,

There is an issue in matching vertex color in a Material.

Here is how to reproduce the issue:
Let’s take a plane of made of 9 vertices (4 Quads).
Just put Green on the 4 border vertices (TopLeft, TopRight, BottomLeft, BottomRight) - Marked by a black circle on the attachment.
And put Red on the other one.

You can see the result on the picture attached.

Here is the wireframe view:

Here is the Material Setup:

As you can see the TopLEft and BottomRight border have a gradient until the midlle where the 2 other don’t (wich is the expected result).

Could you please look at it? I may have missed something but I suspect there something wrong somewhere.

FYI, my mesh was generated dynamically based on CustomMeshComponent with some changes to manage U,V and Vertext Color.

If you need more inforation, please ask. This is a major issue for my plugin.

Thanks,

You can close this one. Sorry my misstake I didn’t take into account the Triangle edge when doing my report.

Thanks,
