Using Displacement on a Decal

Hi @DavidEranen

Can you explain how to use the decal picture for Bump or Displacement?
When I ALT + drag the decal picture to bump/normal map, I don’t get an effect.

2nd:
In Raytraced the Base color is lost:

The Bump map issue has been logged here RH-93784
and the Raytraced issue is logged here RH-94037

Hmm, I thought it’s a knowledge deficit on my side…

Regarding Displacement:
Are there no other settings (quality/smoothing…) than the height?

For now only way to tweak the quality is from the Object properties panel Displacement tab - those settings work per object.

That image has high luminance spikes along the border of the @-sign. I don’t think those can be removed by the displacement.

That’s something you must know, and I didn’t when it’s about decals.
This is quite irritating, especially as the Displacement is not switched on:

I know it’s not a good image for displacement.
I only play around.

Yes, I agree. Ideally there wouldn’t be any need to adjust anything.
