This has probably been asked before but I've been searching for it through the searchbar and it yields no results.
I'm trying to make a custom structure where I copied the actor from an "igloo" from warcraft 3. I know the issue isn't that it's a warcraft 3 actor because I'm also using another warcraft 3 actor (the ice troll hut) for a different building and that one works 100% as expected.
I still can't upload images to show what's going on so, here are some image links (couldn't use imgur, it was giving me "error, try again" perpetually) of the screenshots and the map itself so everyone can take a look.
EDIT: Further testing reveals if I change the actor that if I copy ANY other actor (besides the igloo) then it will work as I want it to. Why does only the igloo actor not work?
EDIT 2: Even further testing reveals that if I copy a new model (like, say, the chieftan's hut model, from the models tab) and apply that model to the actor, it will still work. BUT if I change the model (in the models tab) to the igloo, then it, once again, doesn't work and comes out blank after construction finishes.
EDIT 3: Another test reveals if I change the actor to a known working actor then go into the model of that actor and change it to the igloo (even if it's a default unit being built from a default build ability from a default unit) it will be blank after being built.
If you are using a default working actor say a marine or other standard unit, can you simply change the model of the marine or other standard unit to the igloo? If that doesn't work it's some incompatibility with the model itself and requires actual 3d editing of the model.
That is outside the scope of DATA and requires a modeler and the tools and programs needed to create and/or edit .m3 files.
I am not a modeler but I know enough about models that within the models themselves there are certain settings which must be set for different types of units. I.E. Unit models are not the same as doodads, are not the same as effects. For example, you can't use an impact model on a unit because it's setup with certain animations and settings. And as another example, some models don't have default hit boxes. If you want to use the igloo, it would probably take an experience modeler about 10-15 minutes to set it up for you. (Maybe even less!)
For my map I have tons of custom models and I use a professional modeler to setup all of my custom models. There are dozens of modelers on mapster who I'm sure you could find to help you get the model you want setup. Check out the Artist Tavern and put a post up there. I'll be you could find someone to help you get the igloo the way you want it. Even if it cost like $5 to do it, that's pretty cheap considering the enormity of trying to learn modeling and the SC2 art programs for yourself.
For me its totally worth it and I have beautiful custom models which I didn't have to spend time on which allows me to spend time working with what I enjoy, and thats triggers and DATA.
