Thank you for your feed back.
I have put inside the IGO_Basar folder the new folder ui_nextgen/scheme/Becker_day + Becker_night, as you have explained previously.
I can select the Becker schemes but I can not get any sky or clouds, only a blue background I found it strange even with the standard schemes (IGO_Basar/content/scheme) I can not see any sky/clouds I am not using any customized skins. Do you have any idea why this is happening??? How can I fix it?
All your support will be highly appreciated!
