I’m facing difficulty to get this right. I’m trying to produce room with mirrors on 3 walls, one wall is painted, so is floor and ceiling. Mirrors work as they should but I cannot get a reflection in reflection. In other words, mirrors trace reflections only ones. Second reflection bounce shows my background color.
Just wondering if there’s some kind of tracing limit on Babylon. @Deltakosh Have you faced this situation before?
We did tests with a three.js same setup produced an image as we wanted. Somehow cannot get this working with Babylon. We try to produce an example for tomorrow.
The second question is about .obj format and smoothing groups.
Is it really so that GLTF and Babylons own format are the only suitable file formats that support smoothing groups. We started our development with .obj format but faced smoothing group issues. We had to changes to gltf format. gltf works but a downside are that we cannot re-import it 3ds max. Also, 3DS max Babylon exporter has a tendency of packing “ghost items” to gltf file. Even when Export only selected option is active. For example, if I have a scene with 10 lights and box. If I want to export only a box, sometimes exporter works, sometimes I get 1-5 random lights packed to gltf file. This can be fixed by saving every exportable file to own .max file.
So long story short question about mirrors is our first priority to get working. File format and exporter is second.
