@Martin_Šefl this is your scene slightly modified, I’ll send it back to you by pm
-changed lighting to brute force/lightcache (was set to bf/bf)
-adjusted the tone mapping
-changed the translucent orange material
-changed the outer transparent plastic
-added sharpening
Even though the result can still be improved, the light distribution model in bella is different, and an exact match is not possible. I believe bella supports light being scattered as a result of refracted light through a material, which v-ray doesn’t support AFAIK. Also the HDRI in your bella rendering looks to be slightly differently positioned vertically?
