colored .ply appearing very red

[foobarbecue]

I've got .ply output files from VisualSFM / CMVS, and they import nicely into CloudCompare except for one thing: the point colors have a strong red cast. The .ply file is binary with a header that looks like:

ply
format binary_little_endian 1.0
comment VCGLIB generated
element vertex 2633629
property float x
property float y
property float z
property float nx
property float ny
property float nz
property uchar red
property uchar green
property uchar blue
property uchar alpha
element face 0
property list uchar int vertex_indices
end_header

The same .ply has the correct colors when viewed in VisualSFM or Meshlab. Any ideas?

Thanks,
Aaron

Strange indeed. Can you send me the file? (cloudcompare [at] danielgm.net)

Sorry this took a while, but I got around to uploading the .ply . It's at http://files.foobarbecue.com/unbeatable ... n-0000.zip . I've not got quite a few of these produced by VisualSFM, and all are loading red in CloudCompare. It must be some setting I've messed with in CC...?

Duh, I had a Custom Light which was colored red.

Ah! This is why... I was about to answer that I couldn't reproduce the bug ;)

Hello Daniel,
I face the same problem and I'm wondering how I could get rid of this Custom red Color in order to use this points with cloudcompare.

If it's the same problem, then open the "Display settings" dialog (see the Display menu) and click on the 'Reset' button and eventually the 'Ok' button.
