Hello everyone, if possible I would need to know why when I try to render a model in an insert photo the rendering of the model is transparent as the attached screenshot. I thank in advance anyone who can give me an explanation.

So are you compositing later or is that is straight render from Corona?

Is this done in Corona, and is it possible you are using a non-spherical environment? As it looks at first glance like reflection when the environment is regular 2D (like a back plate, rather than an environment). If not, please let us know the workflow you are following to do the compositing :) Thanks!

It is a Corona render. I'm using the Corona Tag Compositing on HDRI Sky, on Sky and on the main plane. Can't understand why it happens. Thank you for responding me.

Hi,

the issue here is that your sky material's projection is set to Frontal. For environment, the general rule of thumb is to use the spherical projection for your environment.
If you change it to Spherical and play around a bit with the UV offset/length values, you should be getting your desired outcome (attached in this reply).
Additionally, I would recommend using the Corona Sky object in Shader/HDRI mode or with a Corona Light Material in Corona renders.

I also noticed a bug in your scene with the compositing tag, I will further look into that.

Thanks,
Jan
