RTXGI Unity Example Project? #54

Closed smootler closed 2 years ago

smootler commented 3 years ago

Is the project shown in this presentation available anywhere? Even if outdated, it would be highly useful as a starting point for a C#/Unity integration.

acmarrs-nvidia commented 2 years ago

Hi @smootler - unfortunately, no that project is not available. RTXGI is not yet supported in Unity.

@acmarrs-nvidia Any eta?

Hi @smootler. No there is no ETA for Unity integration at this time. However, it is something that we are investigating and hope to have an update on in the future. Please stay tuned.

Hello, got few questions about this topic. What do you mean by RTXGI not being supported? @acmarrs-nvidia Is there some custom API that RTXGI uses that does not work with Unity? as I guess RTXGI is still built on DXR right?

This is my own ProbeVolume using DX12 DXR in URP 2021.2 and it works on GTX 1070. Full Irradiance map and Occlusion map.

What do you mean by RTXGI not being supported?

I mean that RTXGI is not natively implemented in Unity or provided as an engine plugin. At this point in time, you could certainly implement RTXGI's DDGI algorithm using Unity's DXR implementation yourself though!
