Sorry for the mushy post. OK, I made 2 files in Ultrafractal, one with 3 layers, one with 4 layers and saved them as x.psd and y.psd. Now I go to PS and open x.psd. 3 layers show up in the pallete and everything is OK. Now I open y.psd and 4 layers show up and the x.psd with 3 layers disappear. My Q is :how do I combine the x.psd and y.psd into one file in PS with 7 layers? I am a newbie when it comes to PS so please have patience. Thanks.
