Octane does not appear to handle DSON imports too well as shown in the attached renders.
The scene consists of two characters: M4 and M5. M5 was imported into Poser using DSON. I used MEC4D's utility to convert the UV mapping for M5 to M4 and applied the same textures to both figures.
The first render used Octane whilst the second used the Poser Firefly renderer. The M5 character in the Octane render shows artefacts (the black "darts" on the shoulder and torso) that are not present in the Firefly render. The only tweaking I did to the Octane scene was to hide the extremely annoying eyebrow on the M4 figure.
Do I need to change the UV mapping parameters in Octane? If so, how is it done?
