Brushify: Bootcamp - Runtime Virtual Texturing (RVT) for Landscapes, Object Blending and Roads (UE4)

These techniques can be applied to all Brushify Landscapes. In this episode of Brushify Bootcamp, I show how to use Unreal Engine 4's Runtime Virtual Texturing (RVT) feature to Optimize Landscapes, add Object Blending based on the virtual texture and integrate Road Splines into the landscape to act as Decals.

IMPORTANT: RVT requires Volume actors in your level in order to function. Without these the engine will not be able to render to virtual texture. You must also enable Virtual Texturing in Project settings. Please make sure to follow the steps at 25:08 to add the necessary VT Volumes otherwise enabling RVT will simply give you a black landscape.
The steps in this tutorial will allow RVT to work on all landscapes using the Brushify Landscape Automaterial. All Brushify packs support this feature.

We truly love you dude.
You’ll go down in history as one of Unreals most famous developers.

I've been working with these for almost 2 weeks now and it's amazing. It makes any cliff rock looks 100% natural and coming out of the ground.

I can honestly say that I have never looked forward to a Youtube video but when this beauty popped up in in my notifications I was hysterically giddy to open it up and unleash the power of RVT. Thanks for this Joe, one giant leap towards realism has been made today!

[bentripn]

I got the latest Brushify updates today. Looking forward to getting back to landscape work when I'm done in outer space ;) Love you work! Thank you for all you do!

[brunoverde]

Thank you Joe for another awesome video! The initial explanation of what is RVT is spot on!

[brucest]

You've been doing a lot of amazing work across all of your asset packs in the UE4 marketplace. Seems like every other day there are updates lol. Great work Joe. I hope you're doing well.

[oxygencube]

Joe! Dude this is insane. Thanks for this. The blending is a game changer for me. 👍👍👍

[SathishKoththolla]

could you please make a video on ue5.1 how can we use it please ? it is not working in ue5 for me. Thank you it worked when I followed at 25minute

[jwznfgn]

Thank you for this! I was eagerly waiting for this function to be supported!

[tangentarc]

The RVT features are invaluable, thanks. I now have some sweet looking roads, all nicely blended into the landscape.

[FireBert]

Edit Update: Figured I'd answer my own question to help others--make sure if you make any scale changes to the landscape object, update the scale / fitting of the Virtual Texture volumes
That did fix my objects not getting the VT to apply, but I still get a ton of flickering

[lenstobrush]

Hi Joe, I’ve found lately that the ‘set bounds’ option for the RVT volume is greyed out. Is this a thing now or am I doing something wrong. Just found out if you put your RVT-example in both slots volume and the landscape it makes the ‘set bounds’ option available. Hope that helps others.

This is brilliant ... exactly the sort of information I was hoping to get to put RVT into context, both in Brushify terms and in broader UE terms. Any additional videos you could pull together to walk us through the more technical aspects of some of your newly implemented features would be very much appreciated, too. Again: brilliant! THANK YOU!

I have a 4k (4033 x4033) landscape, how should I set the VT_MipDistance parameter in the MI_Landscape? whatever I try, it seems like I'm getting a lot of mipmap looking texture pop-in and blurry textures.

[jendabekCZ]

I love watching these kind of UE4 videos while working on Richard Burns Rally tracks with diffuse & specular maps support... :)

[Julian-B]

Hi Joe, I have a problem. The RVTs to blend meshes into the landscape work for me. However, they turn Brushify's auto material into a blurry low resolution in the distance. Do you know what the issue could be here? I am using UE 5.3.2. Thank you for providing all these tutorials.

[samuelkilik]

wow, , you really did answer all of my question in one vedio

[HPVideoArchive]

Holy cow, you are so smart...I envy you.

36:32 I'm in UE 5 and instead of the "Virtual texture pass type" it is now "Draw in Main Pass: Never, also you won't see it disappear until the segments are deselected.
