Upscale the generated texture
The default resolution of a generated image is 512 x 512 pixels. If you want to use the texture for a larger model, you can upscale it to a 4x resolution of 2048 x 2048 pixels. For example, you have a highly detailed 3D table for a video game. If you want to apply a generated texture to this table, upscaling the texture to a 2k resolution ensures that the intricate details of the clothing are preserved and appear sharp.
To upscale the generated texture, right-click it and select Upscale. Upscaled textures have a 2k icon to distinguish them from the default textures.
Note
You can't edit upscaled textures. To make changes, edit the original texture and upscale it again.
