How to Fix MSB3073 Error in Visual Studio with Unreal Engine

If you’ve been operating with Unreal Engine and Visual Studio to make your tournament or 3D application, you might have experienced the frustrating MSB3073 error. This mistake generally happens during the formation method and can be tough to determine, particularly for those migrating from Unity and its DrawMesh() process.

In this report, we will show you what drives the MSB3073 mistake, how to improve it, and deliver wisdom into recycling Unity’s DrawMesh() functionality to Unreal Engine—so you can bypass this standard problem when operating with Unreal Engine and Visual Studio.

What is the MSB3073 Error in Visual Studio?

The MSB3073 mistake in Visual Studio usually happens when Unreal Engine’s build method fails. The full error notification generally looks something like this:

Error MSB3073: The control “…” escaped with code 1.

This means that a control performed during the build operation has failed. The mistake could occur for several causes, such as wrong build structures, missing dependencies, or problems with your shader code, particularly when operating with Metal shaders or C++ code.

If you’re transitioning from Unity and trying to adjust code such as DrawMesh(), it’s straightforward to experience this mistake due to the discrepancies in how Unreal Engine takes rendering, shaders, and materials.

Why MSB3073 Happens When Converting DrawMesh() from Unity to Unreal Engine

In Unity, DrawMesh() is a straightforward process employed to generate meshes with typical fabrics and changes. This position is adjustable but apart, making it more comfortable for Unity creators to call now.

Yet, Unreal Engine has a more complicated rendering channel. Restoring Unity’s DrawMesh() to Unreal requires comprehending the inner form of Unreal’s rendering method, including Static Meshes, Materials, and Shaders.

The MSB3073 error often occurs when:

There are problems with collecting C++ code linked to customized shaders or generating designs.
Unreal Engine cannot see or accurately collect your Metal shaders (if you’re targeting macOS/iOS).
Misconfigurations between Visual Studio and Unreal Engine.

Step-by-Step Guide to Better MSB3073 in Visual Studio

Here’s a short and easy-to-follow manual to determining the MSB3073 error and providing smooth collection in Visual Studio when restoring DrawMesh() from Unity to Unreal Engine.

Check Build Design in Unreal Motor

The first step is to confirm your body composition in Unreal Engine. If your body structure is set poorly (e.g., targeting the bad platform or operating inconsistent compiler sets), Unreal Engine might forget to collect shaders or source code, showing the MSB3073 error.

Proceed to Edit > Project Settings in Unreal Engine.
Beneath Platforms, confirm that you have specified the right mark (Windows, macOS, iOS, etc.).
Review that your Engine Version and C++ Compiler are up-to-date and check the conditions for the target medium.

Revamp the Project in Visual Studio

Often, Visual Studio can fit onto old cached files or create heirlooms that drive problems. To fix this:

Extend your Unreal Engine task in Visual Studio.
Drive to Build > Rebuild Key to remove any old cached files and reconstruct the whole scheme.
If the mistake continues, try grooming the project by choosing Build > Clean Solution and then reconstructing.

Check for Missing Dependencies

In Unreal Engine, ignoring dependencies whether they’re shaders, surface files, or C++ libraries can start the MSB3073 error.

Confirm that all your help, especially customized shaders or materials, is correctly imported into Unreal Engine.
Confirm that any exterior libraries or plugins (such as Xcode for Metal shaders or DirectX dependencies) are perfectly set up in both Unreal Engine and Visual Studio.
If you’re porting Unity shaders to Unreal Engine, make certain your HLSL code is consistent with Unreal’s shading speech and Metal.

Fix Metal Shader Collection Issues

If you’re targeting macOS or iOS and operating Metal shaders, you must ensure that Xcode is established and perfectly connected with Unreal Engine for the shader collection.

Establish Xcode: If you haven’t established Xcode on your macOS system, download and establish it from the Mac App Store.
Link Xcode to Unreal Engine: In Unreal Engine, guide to Edit > Project Settings > Platforms > iOS/macOS and ensure Xcode is correctly set up.
Assemble Shaders in Xcode: When you create the task for macOS/iOS, Unreal Choice automatically compiles Metal shaders using Xcode. If you experience mistakes, prevent Xcode’s Build Settings for any design issues.

Ensure Correct C++ Code for Custom DrawMesh()

If you’re now executing custom graphic patterns (equivalent to Unity’s DrawMesh()), ensure your C++ code is perfectly composed. Unreal’s rendering approach differs wildly from Unity’s, and a mistake in your C++ code can start the MSB3073 error.

Confirm that you’re utilizing Unreal’s Rendering API (like DrawMeshSection(), SetMaterial(), or other suitable processes) to run mesh rendering.
If you are registering business shader code in HLSL or Metal, ensure it’s consistent with Unreal’s generating channel and syntax.

Cap for File Permission Problems

Sometimes the MSB3073 mistake can happen because Unreal Engine or Visual Studio cannot access critical files due to file consent issues.

Make certain that Visual Studio and Unreal Engine have full approvals to access the guides and files employed by your task.
On macOS, review your Plan Preferences > Security & Privacy to provide Xcode and Unreal Engine have the required licenses to collect shaders and build the scheme.

Deduction:

The MSB3073 mistake in Visual Studio is a typical problem that can occur when assembling a task in Unreal Engine, particularly if you’re transitioning from Unity and attempting to restore custom rendering processes like DrawMesh().

By pursuing the actions above—matching your build structure, rebuilding the task, resolving dependencies, fixing Metal shader collection, and providing good C++ code—you can crush this mistake and successfully relocate your task to Unreal Engine.

Recall, that Unreal Engine’s rendering method is more difficult than Unity’s, and comprehending its system will help you adjust your code thus. Once you’ve decided on the MSB3073 error, you’ll be on your path to developing high-performance games or applications with Unreal Engine.
