Question Decal projector does not clear when changing material

Hello,

I have a huge problem with the decal projector component in HDRP.
When I change the material of a decal projector at runtime with a script, the decal projector keeps showing the old material and the new material. But I expect it just shows the changed material and no longer the old one.
Do decal projectors not clear during runtime? Do they simply overdrawn their space in the texture atlas?

For example, I have a decal projector with the texture of the word "hello". On the wall, the decal displays "hello". But now I change the material of the decal projector to a material with a texture of the word "goodbye".
Now I have "hello" and "goodbye" on the wall, simply overlapping. But it is just one decal projector with one material. When I disable the decal projector, the word "goodbye" disappears. The word "hello" is still there and cannot be selected or deleted.

Also when I disable the said decal projector, the texture from the OLD material will be still displayed but not the new material. Also there is no related scene object for the old decal material. It is like their is a hidden ghost copy.

I'm using HDRP 7.1.6.

Anyone? This is still in the RC 2019.3.0f3.

Please see Issue Tracker Case 1205547.

 

Will this be fixed in the final version of 2019.3? I mean otherwise you cannot really claim HDRP to be production ready, I think.

Decal projectors had and has a really hard history in HDRP. I mean, first there was a bug caused the decal shader to be stripped from builds and now the bug with ghost copies.

 

Please please fix this issue!
