Hello everyone! I am exploring the Composure feature and I think it’s awesome! I would like to put the chroma key output to a texture and assigning it to a plane. Everything is great in the editor but not in the package, there I get a black material. My workflow is as follows: 1. Composure Media Texture Input is fed from the Media Texture (path is in the Movies folder inside the Content) 2. Composure Output is a Render Target Asset 3. Rendered Target Asset is assigned to a material that is set to a plane The result in the editor is what I expected, the problem appears on the package where the plane material is black. Can you guys help me find a solution? I also found that if the Package is set to Development, a long and ugly error appears about Assertion Failed: > assertion failed: > !FUObjectThreadContext::Get().IsRoutingPostLoad > [File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/ScriptCore.cpp] > [Line: 1755] Cannot call UnrealScript > (MediaTextureCompositingInput > /Composure/Blueprints/CompositingElements/BP\_MediaPlateCompElement.Default\_\_BP\_MediaPlateCompElement\_C:MediaTextureCompositingInput\_0 > > - Function /Script/Composure.CompositingElementPass:Reset) > while PostLoading objects Unhandled > Exception: 0xf5b82d90 > 0x00007ff8d8fd9709 UnknownFunction The Shipping method does not give this error but the black material issue. Help!

After setting up your account (github and epic Games), you can access the URL. However, even though this modified version allows it to run in a package build, the Render Target output pass in the package build remains non-working. ---

Since UE4.26, the package build version allows you to run projects including the composure plugin without crashing. However, even with UE4.27, Render Target Compositing Output still does not work in package build. ---
