Hi, This is a user support forum. We cannot restore license revocations.   Licenses are sometimes revoked when it comes to light that they have been sold in a way that breaks the license terms, e.g. by unscrupulous dealers hacking the software and selling multiple copies of the same license, or selling seats on a team/Enterprise license as individual licenses. Unfortunately those same dealers are unlikely to offer any support when the license is eventually revoked. The help pages below give further info: https://helpx.adobe.com/x-productkb/global/invalid-revoked-serial-numbers.html https://www.adobe.com/genuine.html   Dave ... View more

It is an artifact of the rendering engine when edge pixels are not at the default height but some interpolation is needed to set the transition to the next texel which of course is outside the boundary of the material. Render engines will either, treat the next texel as a tiled image (which for a tiled material is a good assumption), treat it as the default height, or provide options. I cannot see any options in 3D Designers render options.  In Blender this is taken care of in the material's displacement node by setting the extrapolation method which sets how pixels outside the image boundary are treated. Changing from the default 'Repeat' which works well for tiled materials, to either 'Extend' or 'Clip' resolves the rendering issue. Substance 3D Render:   The same outputs rendered in Blender with displacement set to 'Extend' (for demo of the issue only, no attempt to match lighting etc) Dave ... View more

Photoshop's scratch disk file is deleted when Photoshop closes, so you should not find it, until Photoshop is open.  You can change which disk the scratch file uses on opening PS by holding down Cmd+Option on a Mac (Ctrl+Alt on Windows), whilst opening Photoshop. Depending on how you use Photoshop, it should be a fast disk with between 100GB and 500GB free space. Although the help files refer to 6 to 10 GB free space, if that is all you have you will quickly run out of space. If it is shared space with the operating system disk you could also crash your PC. https://helpx.adobe.com/uk/photoshop/using/scratch-disks-preferences.html Dave ... View more

The functionality has not changed. The UI interface now has colours on the sliders instead of grey, but they act exactly as they did previously. The coloured sliders are meaningless when targetting individual colours, so personally, I just ignore those coloured sliders and use Selective Colour as I did before. Dave ... View more

You can back up preferences first - then restore them if resetting does not resolve your issue. https://helpx.adobe.com/uk/photoshop/using/preferences.html   Dave ... View more

I had read the title, and the reply to Jane. We know you are using Photoshop for the Web but wanted confirmation of which tutorial you are referring to and that it was a tutorial for the Web version, which you have now confirmed. When you provide a link to the tutorial with the issue, I can take it further for you.  Dave ... View more
