This could include further enhancements to our PBR support, a more advanced lighting models, screen-space reflections, real-time shadows, etc.
The current PBR is not really usable. Here’s a side by side example of a part with and without metalness/roughness. No idea why it turns yellow…
Here’s the expected result with the same metalness/roughness values in another tool.
Not sure but I think the yellow tint stems from the default environment map used in the webviewer. Have you tried using a different one?
