I can do it, but I was wondering if there is a better way.
Large PS file (CS6 and CC) half a dozen texture layers using low res images. Several have blend modes, transparency and even masks. I now have the same images in high res. I want to replace just the image, but not lose my blend/transparency, or masks.
Do I bring in the high res layer, copy the mask over etc? Then delete the original?
Convert the low res images to Smart Objects. Layer > Smart Objects > Convert to Smart Object.
The replace the contenst of the smart objects. Layer > Smart Objects > Replace Contents...
This way you can replace the low res images with the hi res versions. Provided they are the same crop and aspect rarion your mask should be fairly good to go. I say fairly good as you may have made some adjustments (eg. feathering) based on the resolution.
The blend modes and transparency will be unaffected.
Good idea, that sound like a clean way to do it.
