empty (gray) png results

[ben-mkiv]

Hi, for some reason my results are all 0 weighted (rgb values of 127.5)

any idea what this could be related to?

my script:

#!/bin/sh
DAZ_PATH="/home/daz/Documents/My DAZ 3D Library"
EXP="$DAZ_PATH/data/DAZ 3D/Genesis 8/Female/Morphs/DAZ 3D/Angharad 8"

./dhdm morphs-to-displacement \
displacement \
"$DAZ_PATH/data/DAZ 3D/Genesis 8/Female/Genesis8Female.dsf" \
"$DAZ_PATH/data/DAZ 3D/Genesis 8/Female/UV Sets/DAZ 3D/Base/Base Female.dsf" \
"$EXP/FHMAngharad8.dsf" \
"$EXP/FBMAngharad8.dsf"

output:

on a sidenote, my compiler was complaining about the two abs() calls returning int values in diff.cc which was solved by replacing abs() with std::abs() https://github.com/edolstra/dhdm/blob/f56c3c9f7daf7f472dc288fbd47108955bc2ac44/src/diff.cc#L100 https://github.com/edolstra/dhdm/blob/f56c3c9f7daf7f472dc288fbd47108955bc2ac44/src/diff.cc#L141
