Am I making any obvious mistakes in how I'm attempting to render/use things? Should I use the "render context" instead of the raw "render device" code? Or should I possibly just use the whole NoesisApp source code as-is? And any ideas on what's going wrong here and how I'm getting these invalid states and resource barrier issues? The problem only occurs when I use that drop-shadow effect, so it has to do with this and the pixel shader and how resources are handled.

I'm also curious what I would need to do to integrate with Noesis Studio and accomplish things like having my custom components/views show up ... basically, just a high-level overview of what I need to do to make a small integration for my engine similar to the ones from Unity and Unreal and how that's accomplished.

Lately, I've experimented with NoesisGUI in Unreal, Unity and native DirectX 12 and it's been quite fun and rewarding! I have some findings and suggestions/improvements for all 3 I intend to share with you guys soon, and if time allows I'll try to make some YouTube videos or something about this. This native DirectX 12 engine/app project is for experimenting with a 4x "grand strategy" style of game set during the decline/collapse of the Roman Empire and the Great Migration period. As I've been working on this, I'm simultaneously working on the 3D campaign map in Houdini, and I expect it's going to be quite a spectacle, haha. :D

My first question about this would be whether you are able to reproduce the issue using our XamlPlayer (making sure it is running with our D3D12 renderer, which is the default).

We are currently preparing the first C++ SDK with Studio integration. As part of that release, we are going to provide the full source code of a Studio integration (our official StudioTool). You’ll be able to see that Studio is integrated in exactly the same way as the standard samples. There are no fundamental differences in terms of architecture, everything is ultimately based on creating a View and rendering it into a window.

Please keep us posted about your experiments, it’s great to hear that you’ve been exploring NoesisGUI across Unreal, Unity, and native DirectX 12. Feedback from real-world experimentation like this is extremely valuable to us, especially when it spans multiple platforms and rendering backends.

Whenever you’re ready, feel free to share your findings, suggestions, or pain points. We’re happy to review them, discuss possible improvements, and fix as many issues as possible where it makes sense.

I've eliminated all warnings/errors from the D3D12 Debug Layer ... D3D12RenderDevice needed some small modifications to initialize non-zeroed textures and provide an optimized clear color (supposedly performs slightly better). If interested, I can share the code snippets ...

That is very exciting to hear and I can't wait to see this! Speaking of this, I'm supposed to be using the Native SDK from the usual "Downloads" page up top, right? Is there an open-source example of DirectX 12 app using Noesis I should look at as a "working example" to emulate?

One quick thing I can say about my findings in Unity is that we need to have a bit more control over the media player ... I think NoesisMediaPlayer should allow the user to utilize an existing VideoPlayer component in the scene, maybe by marking it with a designated tag.

I also cannot seem to find a repo for the Unity integration source. Is that intentional? I'd be willing to help out a bit and submit some PRs for things like this I come across and fix/change.

Another thing that would be great is if the VS Code language server and even XAML player had a way to set global resources and directories so it can resolve paths properly in real projects for testing and getting correct Intellisense and error-checking info.

I haven’t been able to reproduce any warnings or errors with our D3D12 reference renderer. Are you able to reproduce this using one of the SDK samples?

This is a good idea. Indeed, almost all studios create their own interactivity for audio and video. The implementation we provide is a basic sample intended for you to extend or fully replace based on your project’s needs.

Yes, we are not using Git for this. However, please feel free to share diffs here (or via a ticket), and we’ll evaluate them.

Yes, this has been requested many times and is on our TODO list.
Thank you!

The only question I can think of right now has to with rendering emojis and glyphs ... why is it that Noesis seems to render emojis in a TextBlock just fine if it's in the XAML, but if it's set by a binding in a view-model I just get ?? chars or gibberish?

This is almost always an encoding issue. XAML files are typically saved as UTF-8, which is why emojis render correctly there. When the text comes from the view model, make sure your strings are UTF-8 encoded as well. Once the string is valid UTF-8, emojis will render correctly through bindings too.

Thanks for the feedback and for coming back with an update.

I initially thought this might be related to offscreen rendering and was going to suggest using RenderDoc to compare snapshots between your render and ours.

It’s great to see that you were able to identify the issue 🙂
