Translucency Weight not up-date correctly (uber iray)
1. Load sphere primitive, then set uber iray shader >Base Mixing = PBR metalicity/roughness metalicity set zero.
only set one photometric spot light, in the scene, then render image.
2. set Base color as you like,,
3 set Translucency Weight value to 0.5, then set trasculcency color and tint color , with "Base color effect = scatter, transmit" mode.
4, turn down Translucency weight to "0.0" , now only base color need to circulate for render,. but it not work correctly.
after that, how change Translucency weight , all rendered color not much actuall setting.
5 to see correct color, (rendered), change Share Grossy input "ON" then return to "OFF" (though I can not follow, after that if change translucency weight
DS show correct color or not ) or change Grossy input "OFF" tnen return to "ON" it change rendered image color, case by case. really un-stable.
