Exporting .sbsar does not export opacity

[sacb0y]

I presume this is some sort of bug. 

Here you can see I have a functional opacity.

But when I export as an SBAR the opacity map is not included despite seemingly assigned in the properties.

This is very annoying.

Upon exporting an .sbs it appears there's an error in the export where the opacity is assigned as a color map instead of grayscale. I would say this is a pretty serious export bug.

Hi,
Thank you for reporting the issue. Which version of 3D Sampler are you using?
Can you share a logfile with us?

The latest version 9.1.2 build 3332

Here's a log with two different exports

Here's also the project file (I dunno if it will include the images or not but i figured it might help)

I think the problem is the stylization filter, it appears opacity does not export properly at all if that filter is added, I had to bypass the filter in substance designer to fix the problem.

Hi,
Thank you for the details,
It seems the issue occurs when Image to Material (AI Powered) and the Stylization filter are in the same stack.
Both can export Opacity correctly otherwise.

We will investigate and fix this issue.
