Thanks JJMack for the quick response...
The exported Spherical Panorama jpg comes out splendidly. What remains however, is the original Tif file from which the jpg Spherical was built from. I want to save that Tif File with all the changes I have made on it, obviously. BUT, When I go to save that Tif file, with all the work I have done on its Panorama Layer ( 3D > Spherical Panorama > New Panorama Layer from selected Layers), that saved file is only a portion of original Tif image, showed on the screen at the time it was saved. Small fraction of the original TIF. In other words, if I have to go back and re-edit any blemishes I missed prior exporting the Spherical jpg, I have to start with a brand new copy of the original TIF file and lose all work that was done.
Hope that make sense.
Not really once you merge some or all your tiff layers into a Spherical Panorama 3D layer and create patches for 3d texture How can you make these patches relative to your old 2d tiff file layers. I could understand you reverting your document to before creating your Spherical Panorama 3D layer and placing in your exported panorama as a normal image layer .
After noodling this all day, I made one fundamental change in my workflow and it allows me to re-edit the original file coming into Ps 3D. Initially I was coming into Ps with a .tif file saved out of PTGui. After researching a bit more, I decided to save the output from PTGui as a .psd file. By coming into PS 3D with a .psd file, I am able to use the benefits of Ps 3D (clone seams / blend sky), then export out the 3D .jpg file and save it as a .psd file and most importantly come back to that .psd file to re-edit, if necessary.
For whatever reason, I every .tif file I imported into Ps 3D and saved afterwards no longer were usable if reopened again in Ps.
By changing to a psd file format, I am now able go back to this original file to re-edit the sky or whatever reason, I am able to do so with the .psd file.
Just as an FYI, the next step afterward is to import the Ps 3D .jpg file into Pano2Vr to finish the panorama work prior to uploading.
Thank you and the forum
