Hello
@ikben,
After looking over your Substance, I wanted to run a test using the upcoming release build of the new Substance in 3ds Max integration.
Here are the results:

What was done to achieve this test render:
- Added an environment map
- Ran the automatic Substance to Corona graph generation
- Changed U tiling to 1.5
- Applied material to a cylinder in the scene and rendered

This will be available within the upcoming release.
@jamesjwgallagher,
@alexandar.jupp We have been working on the 1.0 release which will also include the 3ds Max 2019 version of the plugin. This release brings many improvments and lots of new features have been added. You can expect the release very soon and we are very sorry for the delay. We hope the changes brought with this release will be worth the wait!
Cheers!
-Dan
