No probs!

Then I'm guessing you're not on 5.2, which you need to be for 1.19

Try this reinstallation procedure, and it should work fine :)

I see, so it's an inspector shortcut on a material level. I can look into this at some point :)

When you mention that you want to use "substance materials" with SF, the problem is that materials are already using a predefined shader. You *can* use substance textures in SF however, which should get you the look you want, no?

You can already use substances in SF, no? Unless I missed something. You should be able to just drag the substance textures into a standard Texture2D node

Altering them in SF won't ever be possible, that's not something you do on a shader level, thats all handled by substances themselves

It could possibly be that perforce is disallowing access to the file or something?

If you mean Shader Forge 1.17 - update to 1.19 and it should be fine, unless this is due to something else.

It should be fine in 5.2 now, if you're able to upgrade!
