Take a look how Dark Templar or Zeratul permanent cloak upgrades are done.

This seems to do the trick.

<Frame type="ConsolePanel" name="GameUI/UIContainer/ConsolePanel" file="GameUI">
    <Frame type="Frame" name="APMMeter">
        <Visible val="False"/>
        <Frame type="Label" name="APMLabel">
            <Visible val="false"/>
        </Frame>
        <Frame type="Label" name="APMValueLabel">
            <Visible val="false"/>
        </Frame>
    </Frame>
</Frame>

 There's a "UseApm" field on the ConsolePanel frame but it seems to do nothing when set to false

There's many other threads about the subject if you search the forum with "rotation"

I have system for this but it's made in galaxy, if you want it pm me

Use the trigger action "Set Lighting For Player" and loop through each player in a playergroup

You could change the map lighting for the players or you could add a image vignette for the players.

Blizzard

• Here's tutorials made by blizzard --> http://us.battle.net/sc2/en/game/maps-and-mods/

• Here's a trigger tutorial they made for HotS collector edition --> 

  & cutscene editor tutorial -->

• Biggest tutorial for me at least was to just open up blizzards & and other creators maps and look how they do stuff.

Mapster

• SC2Mapster has large quantity of helpful tutorials (https://sc2mapster.gamepedia.com/Tutorials) and forum threads, they tend to be harder to find but with some googling and searching you can usually find an answer or make a thread asking for help yourself.
• SC2Mapster has it's own discord where you can get almost instant help --> https://discord.gg/Jtzt8Su

Youtubers

• DeltronLive has created some simple introductory tutorials for sc2  that follow the blizzards own tutorials --> https://www.youtube.com/channel/UCu5kRp46oLzWek-SRGljTRA/playlists?shelf_id=9&view=50&sort=dd
• Here's a channel who did specific tutorials for the editor --> https://www.youtube.com/user/LazZProductionGaming/videos
• Here's a channel who did specific tutorials for the editor (it's very outdated made during beta/wings of liberty) --> https://www.youtube.com/user/OneTwoSC/videos

This is the first result on google for me for "placement model sc2" ->

Add this to a layout in your map

https://www.sc2mapster.com/paste/c3f659b3

There's options for that in the Map -> Map Options.

- Open the UI  Module in the editor (Shift+F6)

- Turn on XML view in 'View-> View XML'

- 'Data -> Add Layout'; give it a name

- Find it in the left list and paste the fix into the right side text editor

This layout should fix the weapon and hide the xp bar

This layout should fix it, blizzard broke it in lotv or novaops and never fixed it.

(idk how to syntax xml here)

Some of these terraining submission tend to be small scenes, rather than terrains that you could use in traditional starcraft gameplay elements (This has been talked about here before iirc), i don't mind it personally, but I had a thought that you could add the Cutscene Editor to this category also, which excels in making scenes. People could label them as "Made in Cutscene Editor" or something like that.
