Hi, I tried the patch and now it's even worse : it's as if it didn't take my SHLParameter into account : now, the opacity doesn't reduce, unlike before. Before, the opacity was OK, but the shader was not applied everywhere in the scene : when I moved the camera, objects appeared and disappeared, as if it took the parameter into account somewhere and not elsewhere. Any other idea?
