Unreal Engine 4.24 Released!

General Announcements
261

How do you expose the hair root/tip thickness in the groom feature for hair??? I’m only getting hair width through. I’m guessing i have to add something before export to .abc but i have no clue how to do that??! Any help guys?

Figured out the above, the root tip features in the groom node is available via the “master” branch on git hub. Looking forward to more updates to this awesome tool. :slight_smile: Great work guys!

262

Still experience this issue in 4.24. Makes it almost impossible to use this engine version as I can’t afford to wait 4 to almost 10 seconds for each test play.
Anyone else with this issue?

263

Oh ya thought it was just my semi lacking hardware, but yes, same,very annoying long time for play to begin.

264

I added a landscape and hit the CREATE button and it froze the whole engine at 0% status bar, seems that other users are experiencing this also, a 0% frozen status bar.

Just on the side, I got really drunk at a 0% status Bar the other night…It was Unreal…
Eh?
EH!?..
:stuck_out_tongue:

265

This has been my largest issue with this release and has been incredibly frustrating. I can’t seem to replicate it in new files though, only upgraded projects.

266

Only issue i found so far is that using the VR spectator in VR is broken and causes major LAG

I removed the tick every frame and used tick with a delay of 0.0003 to capture frames and it still lags to death
we need a SET MAX FRAMERATE to the scene capture component. using tick to delay capturing is NOT a solution.

267

Any ETA on 24.2 release?
We have build a custom version to fix the Landscape Tesselation bug, but i would rather have people download the offical version from the launcher with the fix in it.

Greetings

268

Scene captures in general in 4.24 screw over VR, its a bug and not directly related to the capture rate.

269

Has anyone else been getting editor crashes (array index out of range) when attempting to import a skeletal mesh exported in FBX 7.4 Binary format in 4.24.1? I cannot import anything, and I’ve tried exporting from both Blender and Maya. Importing static meshes and animations (i.e. without the skin) works however. The crash will also happen if a mesh was imported successfully in 4.24.0 and then you upgrade to 4.24.1 and attempt to open the mesh file, place it in the world, or play in the editor with a character that references it.

Currently the only way I can import a skeletal mesh is to create a blank project in an earlier engine version such as 4.22, import the mesh into that project, and then export it back out to FBX from the editor. That seems to “clean up” whatever problem is crashing 4.24.2. Note that this crashing happens on FBX files which imported fine in 4.24.0.

270

I figured so. every time they update they fix a bug i’m dealing with but cause NEW bugs to kill the rest of development.
All in the sake of fortnite. It’s sad really.

271

I had the same issue, I do believe it is because of the NEW mesh editing tools. If you disable them I don’t see any issues when importing a skeletal mesh but once the mesh editing tools are enabled again CRASH lol

272

Levels with skylight and directional light will not build lighting anymore in 4.24 if upgraded from 4.23…
even if you remake the entire level from scratch lighting stops building on skylight and swarm agent freezes.

273

Oculus button mappings don’t work at all…WOW trying to remove my old bindings from 4.23 to use the 4.24 ones NONE WORK THANKYOU YOU KILLED MY UPDATE -.-

274

Reported a nasty crash today occuring when using skeletal meshes with master pose component, very likely to occur on any project working with modular characters. In our case it’s a blocker, have to stick with 4.22 until this is resolved.

275

    still no fix for scene capture 2d causing lag in VR in packaged builds but runs good in vr preview? ooof. well i guess i’ll wait another 2 months. maybe then they will fix it :frowning:

    277

    So UE-86165 / no physic material from landscape is not fixed? Weak. Makes the engine unusable for my project

    278

    Of course, I’m sorry, but where can I see which license I use. I mean for commercial purposes and for students. [HR][/HR]And also why when you shine a flashlight in the mirror, it shines with a blue color.

    279

    if you accepted the license when you installed UE4 you can use ue4 for commercial projects…but you going to owe the 5% of your income from any project you sell. if your game is released as free you don’t pay the royalties.

    280

    Ok, but what about the flashlight do not tell me? I didn’t apply any effects; this happens when you shine in the mirror.
