Can anyone help with a texture from point cloud issue I am experiencing please?

[gary-b]

I’m wondering if anyone can help me find the problem in my workflow to solve an issue I’m having with the final texture output from Meshlab.

I have a point cloud that I would like to make a mesh in OBJ format to use in Unity.

From the guides, tutorials and pieces of information online my workflow is as follow, once I have imported the mesh.

• Compute normal for point set
• Screened Poisson Surface Reconstruction
• Select and delete unwanted triangles
• Amend normal as required

• Parametrization: Trivial Per-triangle

• Save As Ply

• Transfer: Vertex color to texture (Texture width and height - 4096)

• Export as obj.

This creates a great model but I notice one thing with the texture after import into Unity and that is the faces all have a ‘hard edge’ and the colours are not blended - See attached photos

I see from one of a tutorial that using “Parameterization + texturing from registered rasters” there is an option called “color correction” that I think will fix the issue based on the description. However, there in no option for this in Transfer: Vertex color to texture and I have no raster image for this point cloud.

What I am wondering is, do anyone know of a way in Meshlab to blend the edges of the texture so it looks at lot smoother than as shown?
