Did you change Blend Mode in Material to Alpha Hashed?

Also if you attach scene with bunch of textures it better to Pack All in blend file and then upload here

@Julian Salerno (TricentricAnimations) Have you tried in todays daily build? It's unclear from the report, but I suspect you may be having the same problem described in https://developer.blender.org/T80684 whereby all texture nodes created during import which use png images were getting their colour socket connected to the principled alpha socket, instead of the texture node's alpha socket being connected to the pricnipled's alpha socket.

It's been fixed now for fbx. I don't think the obj importer is quite as advanced as the fbx importer, so it doesnt check if the imported texture is png, and therefore connects nothing to the principled's alpha socket.

This report does not contain all the requested information, which is required for us to investigate the issue. This is 190 image texture files, no .blend, and no description of the steps to reproduce the issue. You say that they are now all black. Where they transparent before? If so, in what version of Blender?

Please submit a new report and carefully follow the instructions.

Adding to @Evan Wilson (EAW) s comment, please don't post that many texture files. Try to create a minimal example Blender project file with one object that shows the issue. The texture can be automatically packed into the .blend file if you enabled File > External Data > Automatically Pack Into .blend.
