Things are not rendering properly (really strange artifacts). See image "substance artifacts" attached.
And also height maps that look great in designer drop to a lower color space when using the substance engine inside C4D. See image "substanceHeight" attached
Of course if I go the Substance Painter route instead, everything works fine, but sometimes you want a fully procedural material to do some effects inside C4D.
As it is now, the Substance Engine integration is a little glitchy.
