I am trying to get the decals working for IOS preview but it seems a bit weird, as if it has no Normal or Roughness or any data (basically looks unlit). I tried changing couple of settings and tried to use different type of Decal Blend modes but nothing has helped so far. I have tried playing around with rendering and Dbuffer decals settings but that did not work either. I have posted some comparison images of IOS preview and SM5 renderer. Obviously the goal is to make it look as close to SM5 preview as possible.
Any help will be highly appreciated. Also please let me know if this is not the right place to post queries like this.
