Unreal Engine 4.9 Released!

[John Alcatraz]

Every time I save my map I get:

"This map is using externally referenced packages which won't be found when in a game and all references will be broken. Perform a map check for more details.

Would you like to continue?"

Just wanted to say the same It worked without any problems in 4.8, but now I get the same message you mentioned and this opens after the map is loaded:



I get this for all maps I have.

You have deprecated the ClearTimer node, but you have not deprecated the SetTimer node:



That's inconsistent!

[John Alcatraz]

The new Collision setting in the SpawnActor does not work the same way as the old one, I have a node which was set to "SpawnEvenIfColliding=false" but the actor still spawned because it was not colliding in 4.8, now in 4.9 the actor does not spawn.

Hey John,

There are now two Set Timer nodes, and the Clear and Pause nodes have been changed as well:



The Set Timer nodes (two options for that, now) have a return value that you can save as a variable, then use that variable in the Clear or Pause nodes.

Thanks Ben, but there were always 2 timer nodes. But why can I set a timer by name but not end it by name?

One other thing, I thought it would be possible in 4.9 to get the default object of a BP so that I don't need to spawn it just to access stuff like it's bounds etc. I can find the new get defaults of class, but there I can't get properties of the components.

So it seems IsHeadMountedDisplayEnabled node doesn't seem to care whether it actually is enabled or not. Even when not playing in VR it still thinks it's enabled. Could be because of Oculus SDK 0.7 I have installed? Hadn't noticed anything out of the ordinary in 4.8 though.

This was updated for 4.9, but I'm not sure I understand your post. Are you saying the actor isn't spawning even though it isn't colliding? I think by default, the node in 4.9 should be set to "Try To Adjust Location, Don't Spawn If Still Colliding" if it was set to false in 4.8. Are you getting something different?

Hi HeadClot,

This was reported 19 hours ago and has not had time to be reproduced or addressed by technicians. While it is possible that something in 4.9 has fixed this error, it is not highly likely. The answerhub post has already been assigned to a technician. If there has been no response within 4 days after the most recent post, please feel free to bump the thread once.

I don't know whether the actor is really not colliding, but you are right, in 4.8 it was "SpawnEvenIfColliding=false" and now in 4.9 it is "Try To Adjust Location, Don't Spawn If Still Colliding". What I am saying is that in 4.8 the actor spawned while in 4.9 it does not. So the collision check in 4.9 seems to be in some way more strict which breaks current behavior.

Ah, I see what you're saying. I think the reasoning behind this is that the new method allows you to set a timer that calls a function, save that particular timer, and then also start another timer with the same function and save that one as well. You can still call it by function name, but clear one and not both. The previous way, you'd run the Clear Timer and it would clear all instances of a timer running that function.

Hi Gigantoad,

This is a known issue and has been reported as UE-19533. Unfortunately, I don't have a timeframe of when a fix will be implemented.

Yep, there was a bug with Spawn Even If Colliding that was fixed in 4.9. I don't think it was working at all in 4.8, so it would have spawned regardless of collision.

Ah I see, thanks for the info. So is there a workaround? Like disconnecting the Rift maybe, or do I just completely uninstall the 0.7 runtime? Just need to be able to test without Rift, preferably without having to remove those nodes from the blueprints entirely.
