Deferred Decal rendering depends on material they are projected on
As suggested in answerhub, I opened a Bug report.
The issue is about Deferred Decals. I am currently using UE 4.7.6
Issue can reproduced on different ways:
Going further, Deferred Decal rendering behavior is coupled to the object shader (in particular, to the opacity of the material it is projected on):
I think this could be actually a work as designed, but then:
Thanks in advance
Decals function by modifying the shading attributes of the material it is applied, so what you are reporting is as intended. The content examples maps we have, provide some of the different types of decal blending modes to communicate correctly with the various other Material Domains and Blend Modes. Be sure your Material Domain is set to deferred decal, and your Decal Blend Mode is set up to render correctly with the material you are applying it to.
Decal Actor User Guide
Take a look at the documentation and the various sections of Decals to make sure you are using them correctly. You can download the 'Content Examples' project to see the images provided in the documentation first hand. Depending on your Material Domain, Decal Blending Mode, the Blend Mode of the material applied, and the Translucent Sorting Priority, your decals will behave differently.
