More details on creating custom presets?

[sfbaystudios]

Hello,

The documentation on presets is OK, but I'm having trouble creating one that works in Unity (Standard Pipeline, terrain). I'm not sure where I'm going wrong. As an example, the BaseMaterail has the alpha set to Glossiness (or Roughess, have been trying both), but Unity does not seem to recognize this. I can see it when I load it in Photoshop, so the alpha channel is there...but Unity just doesn't recognize it.

I'm completely unsure where in the process things are breaking. Are there additional tutorials on how to create a custom export preset?

Hi,
If you see the channels are correct on photoshop, then the issue comes from the way unity reads the maps.
If Unity can't access channels from an image, you might export the map alone.

If you want you can share your preset so I can help you further with it.

Regards.

They are attached. However, this is the preset that, after installing it, made the "Export" button crash the app each time. I think. Not sure. Crash just started after adding this. Was only able to stop the crash by uninstalling and removing all prefrerences, and then starting again.

In Unity, you need to define where the smoothness (1 - roughness) is packed (Metallic alpha or Albedo alpha).

I'm not using URP though, I'm using the built-in pipeline, and this is for the terrain.  My understanding is that the smoothness should be in the alpha of the basecolor map.

The "Correct" answer is not the correct answer.

I don't know what's going on with Sampler -- it clearly has a lot of bugs.  After reinstalling the applicaiton, the alpha works in Unity.  I don't know why it didn't before.

After reinstalling,you imported your custom presets and it worked as expected that's it ?

[sfbaystudios]

Yes, that does work.  🙂 Just be careful to not cause the crash again, or you'll have to reinstall again 😄  

I think I've learned to not do thing in some orders, and do everything in a very particular order. Like a pigeon who turns around 5 times, then pushes a button and gets food, so it keeps turning aroudn 5 times before the button to get food... 😄

Yes, you are right!
But that's why it is so valuable to have your feedbacks to prevent those crashes! 

Thank you again for your patience!

Regards.
