Specific items rendering black.

Hey! I'm having issues with VRay.
I'm on VRay 3.6 using Sketchup 2018 on Mac OSX.VRay keeps rejecting/denying materials to be rendered, for whatever reason.
Same model, same materials between 3.4 and 3.6 seems to refuse to render. In the materials viewport, it shows the materials as black. Any ideas why? attached will bet an example.
The one with lots of black is 3.6, the other is 3.4. 3.4 vs 3.6.
You can see in both versions that they have very dark spots (3.4 seems like it's under-exposed on textures, 3.6 the textures are just not there almost).
I had this problem before, and fixed it by replacing the materials entirely. This is something I don't want to have to do again, especially since it seems like the problem is VRay rejecting it.
This is an example. There are multiple materials like this. https://i.imgur.com/uAZgvEK.png
I used all of these textures in a previous model under Vray 2.x, and they rendered fine. Reusing them in VRay 3.X is the first time they've had issues.
One big thing to note - I've been trying to get this to work between Sketchup 2017 and Sketchup 2018 (3.4 and 3.6 as well) and I noticed one thing - 3.6 lost MORE materials, turning them to black.
The problem does NOT seem to be solved by "reverse faces".
If preferable, I can upload my model, I'm trying to re-render these scenes for my portfolio.
Thanks! -
You probably have some broken links to your image file. Luckily V-ray has a tool for archiving and repathing your images. under extensions look for v-ray>file path editor. this will help you fix the offending textures.

Just had it happen to me last week and this is the correct solution. There was a map that could not be located on the network.
