I got new computer with better graphic card and discovered that some of custom objects I made before appear shiny in the game while they weren't suppose to be: like chicken and cows, reindeers, window awnings, etc. Turns out my older graphic card wasn't supporting something, thats why I didn't notice any shine effect before :(. I have removed shine effect from several dozens of my objects, click here to see complete list of them. If you wish them to look the way they are in my original screenshots, please downloads all the files again. I also decided not to update few of my objects, like Japanese Lucky Cat for example, since they do look fine in shiny version :).
