My image renders transparent - HDRI visible through image?

[archistudio]

Hello Corona users,

I am quite new Corona user (still experimenting with it) and have unusual situation where my image appears to be transparent,to be precise I can see HDRI map through image?
I put HDRI image in Enviroment Tab for enviroment lighting and I am using LightMix to control my lights inside the room.Please see attached image.

Does anybody know what is causing image to be transparent?

I tried to look on the net but I haven't found any similar situation...

Tnx!

It looks like your HDRI enviroment map is set to screen projection mode. You should set it to spherical projection and reflections will start to behave as it should.

Hi Romullus,

yes,that was the problem....at the beggining I set this to spherical enviroment but somehow during the work I turned it to screen that's why I didn't check this....

Many Thanks and Regards
