Unreal Engine 4.9 Preview

[Shirk]

How would I set up a material for parallax mapping?

can you guys fix DX12 it's still crashing and i want to work with it please

This will be an ongoing thing, dont expect a fix overnight. I have found that since Preview 1, where I couldn't even start the editor in D3D12 to now, things have improved dramatically, I only get a couple of obscure crashes now, so there has definitely been a lot of improvement, but I suspect it'll be a while longer before all issues are completely resolved.

In fact, if you are not already, it would be helpful for you to raise answerhub posts for each of your crashes, this is the way to get D3D12 usable quicker, which ultimately is what you want.

Seeing the image in the blogpost (https://www.unrealengine.com/blog/49...early-adopters) I am wondering if there is an update coming to the Shooter Game Any info?

That would be a great idea, it'd be nice to see an updated version of the Shooter Game focusing more on Blueprints than C++.

[KnightTechDev]

The only issue I've had so far is I haven't been able to do a complete build at all using the production settings with any of the 4.9 Preview builds, which I've had no problem with previous engine versions until now.

Hoping that the Unreal Engine 4.9 Preview 4 build works for this.

Well, some time ago they said they want to do an update for the ShooterGame and replace the Slate code with UMG. Since the screenshot shows a somewhat updated UI, this might be it. However, this means more Blueprints (UMG) and less C++ (Slate)

• Core Updates:
  • Runtime Asset Cache is a generic asset cache system that can be used to persistently store data generated during runtime in configurable asset buckets

Can someone describe this feature? Or point-out to some documentation (if it already exists)?

Thanks!

The issue list is three time longer than the update list on the first page

edit: I just counted....it is actually 5 times longer....in preview #4

no update for me

That is the list of issues that have been fixed, not outstanding issues (talking about https://forums.unrealengine.com/show...l=1#post358187).

Cheers,

One of my favorite features of 4.9 is the ability to use reflection captures in a totally dynamic lighting setup and not just the skylight reflection. Looks so much better now!

Are plugins working with content only project in 4.9

Do you have some before/after screenshots that you can provide?

Every preview hoping that issue UE-17458 is fixed, but unfortunately its not. Here is hoping that it will be fixed for the actual release of 4.9.

I am trying to find that feature in 4.9 but I can't seem to find it...

@order66: Here is a comparison:

[DamirH]

Can you tell me here that feature is found? In the light properties?

EDIT: Oh wait, you mean reflection capture actors? What, they didn't work with dynamic lights before?

Engine crashes when I attempt to copy a texture sample from one material editor to another.
