I followed a tutorial, where I can make custom leaves for trees. I added an image as a plane and I should switch in blend mode from opaque to alpha clip but it does not work. It looks like bevore without any change. I tried it with all rendering modes and also alpha blend and alpha clip. The image is a PNG file with a transparent BG but in blender layout mode it shows the BG black. What did I do wrong? Here is the YT tut: https://www.youtube.com/watch?v=TrfIRDw88bM
I was able to accidentally reproduce the problem. I was able to fix it by reloading the image.
First unlink the existing image by pressing the x next to image name.
Next reload the image by pressing Open and search your image.
You should share your blend file if this doesn't work.
