XCC mixer is available on the internet you can download it
https://cnc-comm.com/command-and-conquer/downloads/modding-tools/XCC-utilities?

you don't have to do the same as I did in the video, you can render the map with this render app:
https://www.mediafire.com/file/ow96mtt92cfpgjo/Map_Renderer.rar/file

it will give you 3 images 2 big and one small for map preview the name will be for the small not the same as the map name because the big image resolution is the same name as the map delete the big one and rename the small one the same name of the map, edit it on photoshop if you want to add text shaps anything then put it in the cncnet costume folder maps it will appear in the cncnet client.

That's it.
