1. Best Optimized Method

1.1 Set appropriate color mode

• Set to RGB color, so you can find out whether there is a color difference problem in time;

• When exporting a picture file, you must check "Color Space"-"Convert to sRGB", and check whether the picture has color difference after exporting the file;

1.2 Choose an appropriate picture size

Estimate the size of the picture displayed in the scene in advance. For example, make a 2D label in a 3D scene, and hope that it will be 1/4 of the device screen width when the maximum is displayed. Then we can set the picture width to 270px (taken here) (Mainstream high-resolution equipment width 1080px).

1.3 Set an appropriate picture resolution

It is recommended that the picture resolution should be set to 72PPI.

1.4 Select the appropriate picture format

Determine whether the picture contains transparent parts, if there are no transparent parts, it is recommended to export to jpg or jpeg format.

1.5 Appropriate compressed image

It is recommended to upload to the image compression platform Tinypng for processing: https://tinypng.com/
