FBX Export Colours
Posted: Wed Apr 06, 2016 6:30 pm
Hi there,
I've been experimenting with the creation of meshes in cloud compare with aerial LIDAR data. The CloudCompare documentation and many of the posts on here have been extremely helpful in resolving any issues I've had so far. However, I have a problem that I absolutely cannot solve!
Goal: To produce a mesh and import in Unreal Engine 4, which will be used to generate a virtual fly-through of the data.
My steps:
The mesh's RGB colours are not showing up in Unreal Engine. I have tried various import options to no avail. In Autodesk FBX Review, Blender 2.77, and Unreal Engine 4, the mesh appears as plain white (with lighting shading you can see the mesh bumps and details, it is just missing a texture.) Blender shows some color, but only after a lot of tweaking.
Opening the mesh in CloudCompare shows its colors. Exporting the mesh as a .PLY shows its colors in MeshLab, but the .PLY does not show up in Blender for some reason, so I cannot use .PLY as an intermediary format. Re-exporting the FBX did not work either.
I have tried .FBX binary & .FBX 6.0 binary exports in all of these applications, but there has been no success.
If anyone could shed some light on this issue, that would be great!
P.S. I've checked out this link here: http://www.danielgm.net/cc/forum/viewtopic.php?t=960. Should I try that version of CloudCompare?

My steps:
- 1. Load a large, colorized point cloud into CloudCompare.
2. Subsample point cloud (randomly).
3. Compute normals.
4. Poisson Surface Reconstruction: Output density as SF, Depth = 12, Samples Per Node = 1.5, Full Depth = 5, Point Weight = 4.00
5. Change the output mesh's density and Filter By Value
6. Export as .FBX binary.
