[Phan Ha Duc]

Please Help me
I can't fix the lighting error in this image, It happen in both using Vray HDRI and Using Corona HDRI

Are you sure your hdri is aligned properly with the sun?

Are you sure that's an error?
Any chance you could share the scene, or a part of it where the problem is visible?

Hej PhanHaDuc,

I think this is light "bouncing" from the floor material.
Im not sure how it´s called "Reflective GI Caustics" (?).

Try turning off your reflection from floor material and see if that´s the "problem".
If this is the case and you are not happy with it, use Rayswitch-map in your reflection map.

All the best & I hope it helps.
Nico

That's not a bug. It's light coming through the window to the right from the camera. See screenshot when the window is capped. You can also observe how the pattern changes when you rotate the hdri.
btw, it's not recommended to use Vray HDRI with Corona.

Also, are you sure you can share this scene just like that, with all those models?

Hi Maru, Many Thanks for you support but i still can't understand your explanation. I'm sure that the window hole have been capped by corona portal material. Can you let me see clearer your set? Thank you so much

Portals don't have anything to do here.
What you see is simply a correct result. You would see the same thing in real life. The light is simply "split" by the window frame.
In my example I just capped the window with some solid geometry to see where the light is coming from.
