Full Vision Plugin for Unreal Engine 5.5 (Missing Runtime DLLs)

[sb3658360]

Hi Convai Team,

I am using Unreal Engine 5.5 and I need the FULL Vision plugin (not only the core SDK).

The plugin ZIP I downloaded only contains the Editor DLLs:

• UnrealEditor-Convai.dll
• UnrealEditor-ConvaiEditor.dll
• UnrealEditor-ConvaiVisionBase.dll

But the runtime DLLs are missing from:
Plugins/Convai/Binaries/Win64/

Specifically:
convai_client.dll
ConvaiVisionBase.dll
Vision runtime model files

Because of this, the Vision system cannot start and Unreal shows the error 0xc06d007e when initializing ConvaiSubsystem.

Can you please provide:
ConvaiVisionBase.dll (UE 5.5)
convai_client.dll (UE 5.5)
Runtime Vision model package for UE 5.5
or confirm if the Full Vision build for UE 5.5 is not yet publicly released?

My project depends on Convai Vision, so any temporary build, beta version, or ETA would help a lot.

Thank you!

Hello,

Welcome to the Convai Developer Forum!

From where exactly did you download the Vision plugin?

[sb3658360]

Hi,

I downloaded the plugin from the Convai Downloads page (the Unreal Engine section).
The ZIP I received only contained the Editor DLLs, and did not include:

• convai_client.dll
• ConvaiVisionBase.dll
• Vision runtime model files

This is why I am requesting the Full Vision package for UE 5.5.

I’m trying to understand exactly what you downloaded and where the information about these DLLs came from.

Could you please share:

1. The exact link you used to download the plugin

2. Where you saw that you need

   • convai_client.dll

   • ConvaiVisionBase.dll (runtime)

   • vision model runtime files
     (Please share the source / documentation / screenshot.)

1. Plugin version I used:

I downloaded and used the Convai Unreal Engine Plugin – GitHub version for UE 5.5 from this link:

Releases · Conv-AI/Convai-UnrealEngine-SDK · GitHub

Specifically, I downloaded the UE 5.5 compatible build listed in the releases.

2. Regarding the DLL files you mentioned:

I checked everything inside the 5.5 GitHub plugin (Binaries, ThirdParty, Runtime folders), and I could not find any documentation or reference for the following files:

• convai_client.dll

• ConvaiVisionBase.dll (vision runtime)

• Vision model runtime files

I looked in the following places:

Convai Documentation

• “Unreal Engine – Download & Setup”

• “Environment Vision” feature docs
  None of these pages list or mention these DLL file names.

GitHub Repository

• Searched inside the entire repo for these filenames

• Checked old commits, Releases, Binaries

• Looked into plugin source folders

Still didn’t see any DLLs or notes about “VisionBase” or “vision runtime”.

Where you saw that you need

• convai_client.dll

• ConvaiVisionBase.dll (runtime)

• vision model runtime files
  (Please share the source / documentation / screenshot.)

Hi K3,

Thanks for your response.

Here is the screenshot from the plugin ZIP I downloaded.
As you can see, the plugin only includes the Editor DLLs:

• UnrealEditor-Convai.dll
• UnrealEditor-ConvaiEditor.dll
• UnrealEditor-ConvaiVisionBase.dll

But it does NOT include the runtime files:

• convai_client.dll
• ConvaiVisionBase.dll (runtime)
• Vision model runtime folders

This is why I mentioned those files as missing.

• convai_client.dll

• ConvaiVisionBase.dll (runtime)

• vision model runtime files
  (Please share the source / documentation / screenshot.)

[sb3658360]

I didn’t see these runtime DLLs in the plugin I downloaded.
Here is my screenshot from Plugins/Convai/Binaries/Win64, where only the Editor DLLs are present:

• UnrealEditor-Convai.dll
• UnrealEditor-ConvaiEditor.dll
• UnrealEditor-ConvaiVisionBase.dll

But the runtime files like:

• convai_client.dll
• ConvaiVisionBase.dll (runtime)
  are not included.

So I assumed these are missing from the UE 5.5 Vision build.

For the Convai Unreal Engine plugin you’re using (Convai Unreal SDK Releases), Vision features require additional Vision files beyond the core plugin. However, the error you’re encountering is not related to Vision itself, but to a different issue in the project setup.

For now, I recommend testing with our beta package
https://docs.convai.com/api-docs/plugins-and-integrations/unreal-engine-plugin-beta-overview/installation-and-setup

Also, please make sure you are using a C++ project, not a pure Blueprint project, when working with this plugin.

[sb3658360]

i have a question can you gave me link of pure bluprint version ?

[K3]

Could you please try again? You can now use it with the Blueprint project.
