Decals on 3D floors?

Hi again. I'm trying to put decals on 3d floors but I can't figure out how. I've been told that decals cant be put on middle textures. Is this true for 3D floors as well? If so, how can I use upper or lower texture instead? I see the flags "16:Use upper texture" and "32:Use lower texture" but they don't seem to do anything. What now?

Edit:
Apparently, according to these threads, it should be possible but maybe it's bugged? Or is it fixed? I'm confused. Can someone confirm or deny this?

Sometimes i just place separate linedefs with midtextures of decals. I know it's common method for ports that don't have decals.

That won't work in my case because I need to dynamically be able to add decals. Like with SpawnDecal for instance.

Make your "Decal" as an Actor with WALLSPRITE and done!

Can you give me an example of how to do that? I need a way to get the angle of the wall then, don't I? Otherwise, how do I know which angle to spawn the Actor at?

Code:

Actor REDX
{
   +NOGRAVITY
   +WALLSPRITE
   States
   {
      Spawn:
         REDX A -1 Bright
   }
}

This the a Actor Code:

Code:

ACTOR Hand 8600
{
Scale 0.15
RenderStyle Translucent
Alpha 0.8

+NOINTERACTION
+WALLSPRITE

States
 {
 Spawn:
 NULL A 0
 
 Hand:
 EMIA Z 1 Bright
 Loop
  }
}


You can Set his angle in MapEditor or :

DECORATE - https://zdoom.org/wiki/A_SetAngle

I'm not sure what all of you are talking about, decals render on the sides of 3D floors just fine. And I don't see any reason for why pre-placed ones wouldn't either.
