hcmetal Posted September 15, 2018 Share Posted September 15, 2018 Hello everyone, I have been trying to create my own hdr environment map and use it in Babylon. A panorama is rendered in 3s Max 2019 using the V-Ray Next (4.02.04) sun system and saved as a .hdr file. The .hdr file is then loaded into Lys and converted to a specular .dds file, following the instructions from https://doc.babylonjs.com/how_to/physically_based_rendering Looks fine in Lys: However, in Babylon some strange things are happening PG: https://playground.babylonjs.com/#FDQ594 Two things to notice: 1. Reflection on the sphere with chrome pbr material. The sun looks funky: 2. Reflection on the ground with a none metallic pbr material. The sun looks funky too: Both materials have very sensitive roughness behaviour. More detail can be found in the PG. The .hdr output from Vray is here: vrayhdrtest.hdr I suspect something has gone wrong during the conversion in Lys, or the original render out of V-Ray has some problem. Hope someone can point me to the right direction. Thanks a lot! PatrickRyan 1 Quote Link to comment Share on other sites More sharing options...
