Race.......

There is something that i wanted to try but it failed...

I was trying to make a choas orc race but i needed to use custom unit for buildings. But when i test it is like i can build where ever i wanted to. edge of cliff, in building, into trees. How do I not make this happen? I am not sure if the campaign use trigger for like replace a normal grunt with a choas grunt.

Are you sure you're using a building as a base unit?

Give your building some pathing in the unit editor (you'll need Blink from the tools forum, aka Enhanced WE)

i do have the blink.. i am not sure if it is a base unit but i could build anywhere i want. how can i avoid this from happening tho?

when you use unit editor and click ctrl + n (create custom unit)

they should show a screen where you pick a unit
that is the base unit if base unit is building , then you should not be able to build off cliff

chaos peon and grunt , i think its in the editor itself
