Here another project i have done a year ago, just improved the model and the material. So this high poly model with 116159 verts, 104670 faces and 209340 tris. This model can be downloaded and used for any project. As for the Hdr image, it has been removed due to Licensing but can be downloaded on HDRIHAVEN. Hope you like it guys and as usual feedback are welcome
The blender file tells me that the HDRI was called "glass_passage_2k.hdr"
