Fish eye not stacking

Hi there, I took some HDRDNG 5 photos with the plug in in my Theta Z1 and it did not stack them in camera. I had to merge them after the fact. Anyway to remedy this?

Hi, @ivajan
How did you merge hdr.dng images by yourself?
DFE HDR-DNG mode can make 2 files at one shot. One is .dng image and another is _hdr.dng.

Very courious. Please show me the files in Dualfisheye folder of your Z1.

Toyo.
