From this tutorial by the UE5 devs:
The last method without Uvs was a very interesting approach. Someone was kind enough to share how to set this up using Blender and Ue5:
Hope someone finds it useful.
Another thing I am hoping for is Nanite having vertex color layers like Blender. Would be very useful. The author in the third video points out vertex color might be an issue in nanite due to distance from the camera so its preferable to blur it to reduce the poping of color as you approach the asset.
From the video here which was done by Simon Verstraete :
Vertex paint seems to hold up pretty well. The vertex color was definitely blurred to reduce the vertex color popping in as the camera draws near.
@VictorLerp Pls is there anyway we can get a screenshot of the material setup Arran Langmead used for the vertex color materials setup in the tutorial he did. I think this might be helpful to other ue5 users?
