Interested in AI in Unreal Engine? This quick tutorial walks through a new plugin that leverages TensorRT to efficiently render neural post-processing in UE5.

We’re accelerating Unreal Engine’s Neural Network Engine (NNE). NNE is a common API that allows for seamless integration of neural network features in @UnrealEngine 5. Now, developers can utilize a new plugin that adds TensorRT for RTX as a runtime option, resulting in higher throughput on NVIDIA RTX GPUs. Read the tech blog for more details and a sample project 👉 nvda.ws/4w3nffS

Real-Time Image Based Lighting in the NVRTX branch of #UE5. This scene is lit with HDRI only, no light actors. Still, the Restir algorithm is able to render dynamic and accurate shadows from the sun pixels in the image☀️

The latest NVRTX-5.4 branch includes a new bonus plugin: 'Asset Tech Auditor'. In this thread, I will highlight few features… P.S. The plugin is completely implemented using #UE5 editor utility widgets ;)

After running the tool to analyze assets, detected issues can be automatically fixed by the tool💪 Few exceptions require manual fix in DCC. Hovering the mouse over these checks provides helpful metrics for fixing the asset.

The tool is based on a plugin architecture for implementing auditing checks. Users can expand it by implementing more validation plugins and support additional asset types. Check the readme for a high-level explanation about extending the tool. github.com/NvRTX/UnrealEngin…

NvRTX-5.4 non-preview finally released. Some good cvar/control refactoring (much stuff now available in PPV). Good ReSTIR GI improvements.

Ported one of my old MentalRay shaders to ShaderToy. The shader is for making textures tileable in run-time using one texture sampler shadertoy.com/view/XffyDn

The latest update to the NVRTX 5.3 branch introduces partial colored transmittance github.com/NvRTX/UnrealEngin… I think many #UE5 devs -including myself- will appreciate getting accurate and dynamic colored translucent shadows in real-time without light baking :)
