We have been using Pix4DFields for processing multispectral projects since they support the use of Sentera calibrated reflectance panels automatically for radiometric calibration. I see in the latest D2M faq regarding supported multispectral cameras that M3M camera model is supported, but not radiometric calibration for that model. I also see in the latest D2M documentation that reflectance factors for each band can be typed in and a box can be drawn on the reflectance target. I remember in past versions of D2M multispectral workflows would have that portion of the calibration process greyed out. Is this still the case for the latest version of D2M or can those reflectance values and drawn target box be manually entered in now?
Pix4DMapper had a similar workflow where, even though the Sentera reflectance panel was not automatically registered with the calibration process, you could manually add those calibration target images and type in the band reflectance factor values.
