| Nov 2, 2020 at 9:34 | comment | added | Robin Betts♦ | @ChameleonScales yes, it's annoying that the 'transparent depth' seems just to be an accumulator.. total number of transparent surfaces passed, at all stages. | |
| Nov 2, 2020 at 7:04 | comment | added | bstnhnsl | @ShantanuAryan unfortunately that’s a solution i had in my early stages of exploring. | |
| Nov 2, 2020 at 7:02 | comment | added | bstnhnsl | @ChameleonScales I hope there will be a smart light path in a future update. Would solve a lot of my daily struggles... | |

| Nov 1, 2020 at 4:14 | comment | added | ChameleonScales | For a "one render pass" solution I'm pretty sure we would need either light linking or a smarter light path node (one that memorizes ray types throughout the whole path). So in the current state of Blender you have to composite 2 renders: one with your "portal" light source using a pitch black wall around the door and one with your normal light source, without the wall. You can then simply add the 2 renders together and you should get the right result. PS : if you also use an environment light, only use it on one of the 2 renders of course. | |

| Oct 30, 2020 at 9:46 | comment | added | jachym michal | I feel like Robin Betts' Magic Goggles answer could be a good starting point, but I can't figure it out myself :). | |
| Oct 30, 2020 at 8:53 | comment | added | bstnhnsl | @JachymMichal Hi :). Basically what you can see in image 4 without the shadow from the corridor. There should be "outer" and "inner" light sources, the doorframe should cast a shadow. (i have my wonky light-blocking corridor for scenes, where there is no other lighting). | |
| Oct 30, 2020 at 8:42 | comment | added | jachym michal | Hello :). What's the desired result if there are more lights in the scene? Should the doorframe cast any shadow at all? Or should all lights only shine through the transparent door? | |

| Oct 27, 2020 at 13:59 | comment | added | ETHAN DAY | another thing you could maybe try, is making a light area on the ground in front of the door, and shape it into a cone | |
| Oct 27, 2020 at 13:49 | comment | added | ETHAN DAY | Although, portals are usually used for indoor scenes, I'm not sure how it would affect your scene, but might be worth a try | |
| Oct 27, 2020 at 13:47 | comment | added | ETHAN DAY | did you enable portals in the light settings, because if not, that may be exactly what your looking for. | |
