Hi, if you need to use the mustard right now, theres an easy fix: open the material and go for the transparency settings. Rightclick the Transparency function and choose Edit function. If you take a look at the Texture map node of transparency channel, you only have to invert the "colors", theres a little black/white icon at the upper right side of the bitmap preview. With this icon you can invert the alpha map , then the flower should look fine. I am sure that Greenworks will offer a fix soon. best, Walli
