Getting Started with VRS & Foveated Rendering using HTC Vive Pro Eye & Unreal Engine

[bipul mohanto]

So far, this is the only, and best foveated rendering direction available in the internet. Thanks to the author, @MariosBikos

Hi @MariosBikos, one quick questions, are branches UE 4.23.1 and UE 4.24.2 developed for win64/win32 machines? I tried both of these branches to build and debug, as you mentioned on my 64-bit machine. However, each time it failed to build. P.S. I used the Visual Studio 2015 community edition.

Is there any support for UE 4.27? I have a project that is built already in 4.27 but could benefit from foveated rendering on our new Vive Pro Eye. Thank you so much for the detailed documentation!

I have a few questions for clarification:

1. I have cloned the 4.24.2. Instead of some minor errors, the UE is launching. In part 1, (8) to launch the UE, do I always have to follow the step: Open the .sln, then Debug > Start New Instance? Or is there any other way that I can directly run UE like a normal installation?

2. Part 2: 12, 13, 15: I have downloaded SRanipal v1.3.6.6. Extracting the .zip file includes Plugins\SRanipal. I am copy-pasting this plugins folder in a new project under a different directory than the unreal engine cloned (C:\ directory). But in Edit> Plugins, I cannot see the SRanipal plugin.

C:\Users\local-admin\Downloads\unity\SDK-v1.3.6.6\SDK-v1.3.6.6\SDK\03_Unreal\Vive-SRanipal-Unreal-Plugin.zip

3. Part 2: 14, I do not see an error in Dartboard.h. But if someone has a problem, did you mean editing SRanipal.Build.cs as follows:

        PublicIncludePaths.AddRange(
			new string[] {
                //Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipal/Public"
                // ... add public include paths required here ...
                // from tutorial
                PublicIncludePaths.Add(Path.Combine(ModuleDirectory, "Public/Eye"));
                //PublicIncludePaths.Add(Path.Combine(ModuleDirectory, "Public/Lip"));
			}
            );
				
			PrivateIncludePaths.AddRange(
			new string[] {
                ModuleDirectory+"/Private",
                ModuleDirectory+"/Public/Eye",
                ModuleDirectory+"/Public/Lip",
                Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalEye/Public",
                Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalLip/Public";
                // ... add other private include paths required here ...
                // from tutorial
                PrivateIncludePaths.Add(Path.Combine(ModuleDirectory, "Private/Eye"));
                //PrivateIncludePaths.Add(Path.Combine(ModuleDirectory, "Private/Lip"));
            }
            );

I have resolved all the previously posted issues. I want to delete the post, but I am unable. Could the page administrator please take action?

Hi @bipul mohanto,

How did you resolve those issues?

Will your solution help other developers in the future?

[bipul mohanto]

@VIVE_chengnay, I guess the UE 4.24.2 version was not compatible with the sranipal SDK I was using. Tried with 1.3.6.6, 1.3.6.8, 1.3.3.0. However, now UE 4.23.1 doesn't show the plugin recompilation error.

The main problem is still unsolved, the variable rate shading I can see as static. Do I need to add any blueprint to make the variable rate shading work? The tutorial did not say that.
