Set URP Decal Projector opacity by code?

I’d like to pulse a decal projection in my project but I haven’t found any opacity property (or similar) in UnityEngine.Rendering.Universal.DecalProjector class.

Is it possible to set the opacity by code?

I’m using Unity 2021.3.5f1 (Universal RP 12.1.7)

I’m sure you’ve reviewed the scripting api documentation for that class, correct? If so, what have you found?

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

  • what you want
  • what you tried
  • what you expected to happen
  • what actually happened, especially any errors you see
  • links to documentation you used to cross-check your work (CRITICAL!!!)

You may edit your post above.

The DecalProjector property you need is called fadeFactor :).

Some more information about what I’d like to achieve is to pulse a decal from lets say 0.2 to 0.5 opacity over time.

I’ve checked the documentation:
https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.1/manual/renderer-feature-decal.html

After further research I found the component documentation as well:
https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.1/api/UnityEngine.Rendering.Universal.DecalProjector.html
The component documentation at least mentions to set its transparency.

My expectation was to find the same variable name as shown in the URP Decal Projector component :slight_smile:

Thanks @ Kreshi, that is the solution!
The opacity in the URP Decal Projector component can be set with the Universal.DecalProjector.fadeFactor property.

Problem solved.
