Hello! Can anyone pls help me on this, I'm new on substance painter so im kinda stuck it would be really great if someone helps
You have an empty layer at present. To apply that material to the model, either use a brush and paint it on, or add a fill layer and add the material to that.
Take a look at the foundation courses here:
i watched few foundation courses, here it seems height maps are working but not color
Could you share a video of what you're doing as well as a log?
