Reflection map issue after exporting from substance painter

[joon]

Hi,

I exported the maps from Substance Painter following the guide on their website. I don't know why this huge white patch appeared on the top of the mech head, when the rest of the model is doing fine. The texture set is split into two, and the leg texture set doesn't show it either.

As you can also see, even once I turned the reflection off for the metallic, the dielectric still have some residue of that artefact.

Attached is the white patch in question, and the second image shows what happens when I turn off the specular for the metallic material. Third is my reflection map.

It renders fine in SP.

EDIT:

Platform / OS: Windows 10
KeyShot version: 7.2.109
Modeling system, including version: .OBJ file, textured in Substance Painter, exported following https://support.allegorithmic.com/documentation/display/SPDOC/Keyshot
Steps to take to reproduce the problem: Just turning on/off reflection map

Hi,

Can you share the KeyShot scene?
Please save as ksp (File > Save Package...).

This has nothing to do with the Specular map.
In your scene the Opacity map is using Box instead of UV mapping. Changing to UV mapping solves the issue.

Btw, why are you still running 7.2.109? Our latest release is 7.2.135.
