Summary0000599: Blood decals only show under certain circumstances online
DescriptionBlood decals will show for all actors offline, as expected

However, offline, the only way to get blood decals to show is to have a player jam a moving floor by standing in the gap between the floor and the ceiling.

Monsters and players will spawn blood actors when shot, but it will not cause blood decals.
Steps To ReproduceStart Doom 2 MAP15 online
Jam that first elevator, and stand near the wall, you will see blood decals on the wall.

Shoot a monster or player near a wall, you will not see blood decals on the wall.
Additional InformationTested in 98D and 98E-r3299

It is possible that these blood decals have more bugs that are random, there were some blood decals that I couldn't see, but the other players in the server could.

 This is interesting. While it's trivial to allow the client to spawn blood decals, the effect will not be desired. The amount of blood splatter on the wall is determined by how much damage you have done to the actor, which the client knows nothing about. There is also an effect for clients who have high ping, an example would be the client died right after he just shot an enemy and saw blood behind the enemy yet it did no damage. (however, could be fixed as we could wait for the server to respond to our hit then spawn the blood). Then there is one more problem with doing this client side, every other client has to know about it too.

So another way to do this is to tell the server to spawn the blood decals to the clients, but this takes more bandwidth which we may not want. Actually, we do not want that.

If in the future we decide to tackle something like this, both client and server need to have the same random seed, which is very very difficult to do.

 Related to 1838 because suppression of prediction is done due to the decal hack not extending to blood decals. This SHOULD be an easy fix after my code for clientside puffs gets pushed through.

Didn't submit a pull request cause clientside puffs needs to get done, but this makes decals work online and offline. Tested with a large variety of permutations with all the new cvars we have, they all work.

This should be good. Hopefully.

 As discussed on bitbucket, there should be no additional cvar for this.

 From the testing we've done (Shooting people, watching others shoot one another, etc.) it seems to work great.
