E57 Scalar Saving Issue

[wuhanshuo]

I have an E57 file with X,Y,Z,R,G,B,Intensity information. I want to label it, i.e., add a new scalar field 'Material'. However when I saved the file as E57 and open the new file, the second scalar field 'Material' just got lost and only 'Intensity' was there.

Besides, if I delete the original 'Intensity' field after labeling (only 'Material' field was kept), and then saved the file, the field named ' intensity' was still there, but its values were replaced with material labels.

If I save the file as TXT after labeling, the intensity and label fields are always saved perfectly, but TXT is not what I want.

It seems the E57 file only accept one scalar filed named 'intensity' exactly. Is it because the file header needs to be modified somehow?

Correct, E57 files don't support the concept of generic scalar fields. Only 'intensities' are accepted (and CC will use the SF named 'intensity').
