Thank you! You are the nicest Lazer Potatoe I've encountered on the internet.

[@unicodePug]

Thank you, Potato.

[@xylvnking]

thank you so much

[@Kaonuri]

Instanced Properties is game changer. All developer need to know this.

[@NongBenz]

Some data access methods I wasn't even aware of here - Thanks for putting these out.

[@ShortBusTrip]

This was fantastic. I'm working on data storage on my own videos now, using the BP Assets. Found all this information super helpful and will make the quick change to using the soft class references and push my viewers to do the same thing. I really appreciate this talk!

[@chrispetersen3613]

This video was super helpful to me in regards to understanding when to use data assets. Thanks for putting together this presentation!

[@j05hau]

I have been living under a rock. This is pure Epicness

[@sebastianavena]

Such a wonderful and useful talk! Super well explained, thank you VERY much!

[@korypostma]

In spite of what is being said in this video on TSoftObjectPtr, they can be more problematic than not for basic things like movement speeds, basic default inventories, etc. So my advice is to choose wisely which are and are not TSoftObjectPtr or TObjectPtr and pick the best one for your particular use-case. If you have 500 hat cosmetics, of course you want those to be loaded as soft pointers, but if you have a UDataAsset that is applied to nearly every character, that should not be soft.

Where can I find documentation on how to use the WebAPI Plugin mentioned at 19:00? Seems incredibly useful but I can't find a shred of documentation on it

[@bcur5376]

It's also not working as of Unreal Engine 5.3

[@dannykay4649]

Very useful info.

[@arsen1156]

Awesome tutorial

[@MartinDlabaja]

Why do you show us Web API plugin, but it has no documentation and no one on internet knows how it actually works? Please fix that!

[@Hyperlooper]

Same issue! It isn't currently working, at least not how he shows it.

[@t3hpwninat0r]

Take a shot every time Jack says data

[@marcoieraci]

what about local files? eg. 3d models input in a packaged project

[@Elmarath]

How can I make an asset picker Editor Utility Widget like in the Editor?

[@JackDCondon]

A talk I did at UnrealFest Goldcoast 2024 will be published soon with some great tips. I'll follow up with a link

[@leon004leon]

Unreal really has no chill with these rapid-fire uploads

[@skippyzk]

Unreal is so freaking weird. I hate it. I love it.

[@user-tq7vo4is7w]

Instant like

[@EstebanLopez-bn9pd]

Wait. Australia is real?

[@rc-st9pg]

What the hell is an evangelist? Is this new bazaar woke BS now a religion?

[@dogstar9455]

unclear presentation.

[@dertythegrower]

put an hour between each new content.. you are flooding the subscription page with dozens of content at once. And each one is one hour long. Make sense?

[@Derjyn]

They dump the talks every year, as fast as possible. It's nothing new, and if you follow any industry that has events with multiple talks occurring at the same time, you will see the same media dump rates. This allows for teams that attend these events in person to rapidly shift attention, get caught up, etc. This also allows teams with members who are remote to the event to keep up. Make sense? This type of content isn't for kids looking for a 7 second dump of garbage entertainment. It's for professional and independent developers, artists, etc. Unsubscribe and move along if this scene ruins your day.

[@izzyrodmon4249]

No offense, I appreciate they share these videos but man, they need someone to manage their KZbin channel correctly, I really can’t keep up with your long videos every 10 mins lol.

[@jipjomon]

What an odd sentiment - there's no time limit on the videos. It's a library of sorts you can browse at your leisure and select videos to watch when you need to learn about the topic, not a funnel where you need to catch everything in your mouth right when it comes out or its lost forever.

[@dertythegrower]

Stop putting all the content out at the same time.. you are going to lose subscribers because it ruins the feed with entirely all your stuff

[@Extrone]

This is an Infotainment channel, not an entertainment one. If you don't want to be spammed, unsubscribe. The sub count doesn't matter here!

[@xtsdagger6956]

Get to the point. Get to the point. Get to the point. This should have been a 5 minute video.

[@NongBenz]

He covered at least a half-dozen ways to store and access data across C++ and Blueprints and provided their differences and benefits as well as fast-fire demos on how they can work together. Godlike that it was less than an hour, great presentation. Get real.

[@xtsdagger6956]

@@NongBenz I suppose his rate of data transmission matched well your intake. I am glad you had a good experience. Have a great day, and good luck on your journey

[@Derjyn]

As I commented in reply to someone else: This type of content isn't for kids looking for a 7 second dump of garbage entertainment. It's for professional and independent developers, artists, etc.

[@xtsdagger6956]

@@Derjyn Thank you for your reply, sadly, I think you intended to insult me. Lucky for you, I am not offended by your thin skin. I am a professional developer, and have been one for decades, and I know how valuable my time is. If you found value in this presentation, great! I am glad for you. I am not looking for your straw man, as you put it, "7 second dump". Just people that will get right to the point, state the point quickly and clearly, and then stop immediately after their point.

[@xtsdagger6956]

First useful word of the presentation starts at 4:43. Watch it again if you don't believe me.

[@morningwombat]

unsubbed

[@wenpluto4282]

bye!

[@Pepnewfull]

I love you unreal but please stop the spam. i unsubscribed because I don't want to scroll for an hour just to get my normal feed
