Hi Adam, thanks for you answer!
I just try to replace my texture file from ai to psd, and the texture come back! but the edge still have some white colors,
for my previous question, is it just the matter of the file format?? ( sorry that the question may sounds stupid, cause I am very new to c4d)
and here are the setting for my texture, please kindly advise if anything I set wrong that makes the edge still have some white.
thanks so much!
