What are your camera settings?

Thanks for your answer I going to try the settings that you give me.

Hello Rodrigonotor,

Try checking the spiral rube object as Hidden from Global Illumination (and or Hidden from Reflections/Refractions, try both options) in that object's Parameters panel.

This is a cool trick when you need one emitter enclosed inside a glass body, like you have here.

Show us the results.

Cheers

hi Rodrigonotor
i tred a scene using this hdri image and i calculate the focal lenght of the camera
with sketchup i find 45 mm but this give false result and false dimensions; the buildings in the photo can't give the best result ; we need a plan (dwg for examlpe ) ; i use for that an image from google earth; and the best result is 35 mm
if you see image property the lenght focal is : 35 mm
you can verify your camera; create a cube from clear tile in the photo and see if it have the same dimensions

good luck
