While I don't really use the 3D tools in PS, the Lighting Effects is very useful and important to me. I use this to create a light on my subjects in portraits. I really hope that this tool would not be removed from future PS.
As per https://helpx.adobe.com/photoshop/kb/3d-faq.html, Render Lighting is included in the 3D toolset that is being removed from Photoshop entirely. I would like to request an updated, non-OpenGL version of this filter to be added back into Photoshop.
I have never used Photoshop's 3D tools but I use Render Lighting for a lot of my 2D work. I already use the Substance suite and there are no point or spot lighting controls in those programs; utilizing a third rendering program just to get a spot light effect on a flat texture is time and resource intensive, when Render Lighting gives me great and controllable results very quickly.
I have rolled back to 22.2 and will remain there, but the official advice to keep 22.2 installed alongside 23 (when released) just to use one feature seems like another waste of resources and space. It would be great to see a new version of Render Lighting updated and added back into Photoshop independently of the other 3D tools.
