I have been working on creating a 3D Pdf with Photoshop. However after I have updated my Photoshop CC to 2018, the textures on my .obj file appear as white. Before the update the textures were working. Any ideas as to why this has happened?
The easiest way to get this fixed would be to re-link the image back to that Balloon object.
Do you have the original image?
If so then select the ballon and re-apply the texture.
Otherwise we would need to understand your workflow and figure out what happened.
