I am having an issue with using an HDRI environmental image to light an indoor scene. It was working correctly when all of the sudden the shadows stopped showing in the render.

I don't recall doing anything particular between one try and the other, except for adding a plane lamp to brighten up the scene a little bit. After this happened I deleted the plane of light just in case that was the reason but still no shadows.

I leave my environment settings, my render settings, the preview of how the shadows should be and the render after hitting F12.

One thing that is worth mentioning is that my graphic card ran out of memory for the first time. I solved this by switching to CPU and back to GPU Compute, but maybe it has something to do with the main problem. I leave also my system info and I have a NVIDIA GeForce GTX 960.

World settings and render preview - correct shadows

"final" render - sorry for the horrible denoising, it was a really quick render

render settings

model complexity

System info

EDIT Here's the glass settings

EDIT Camera's settings

    $\begingroup$ Hi. HDRI provides lighting samples, but I don't think HDRI's can cast shadows. This means that if you had shadows in the scene, they must have been coming from some kind of light source (directional-light, spot-light, point-light, or area-light), or from an emissions panel if you're using them. Double check on what lights are in your scene. $\endgroup$ Jun 1, 2020 at 17:25
  • $\begingroup$ Hi! thanks for the answer, but I've been casting those shadows with the HDRI. I cannot explain why or how but I got those shadows by simply rotating the HDRI. I have some portals in the windows, maybe that's why? I managed, a few hours ago, to render the same view casting the shadows, I don't know why but it started all of the sudden :/ $\endgroup$

  • $\begingroup$ Sorry, I was thinking EEVEE, not cycles. Any chance you switched by mistake? Aside from that, I don't know what you changed to make the shadows disappear, but you could try defining new ones by using an "Irradiance-Volume" light probe. $\endgroup$ Jun 1, 2020 at 17:54
  • $\begingroup$ Tried it, still no shadows! the funny thing is that I have another scene in the same model with the same illumination and everything and that one is working fine... it's just with this one.. $\endgroup$

    $\begingroup$ I have no clue what you are trying to do with the nodes for the glass, do you? Please explain. Otherwise try the setup on this post: blender.stackexchange.com/questions/2558/… $\endgroup$

So, I was able to solve the problem by cleaning up the model. I deleted a lot of objects and now it renders correctly as usual. I guess it was a problem with my system and nothing with the model itself. Thanks again to everyone for the assistance and help! Have a great day
