NodeMaterial broken with floating origin / large world rendering

Bugs

Hey there,

I am still working on integrating the new floating origin feature in my projects, and ran into another issue related to node materials (similar to Large world rendering has issues with NME specular lighting I think)

My own testing hinted at objects with this kind of node material being stuck in camera space, so the camera could be inside the cube, which would explain we don’t see it :thinking:

Maybe you know what’s this coming from @georgie ?

  • view matrix: View
  • view projection matrix: ViewProjection

In your material, the world and view matrices are not correctly capitalized. Once corrected:

Thank you for reporting! Here is a PR which makes the feature a bit more forgiving and supports lowercase matrix names
