Double check that the height map tool "top layer" box is checked, verify the height you are setting it to (or just use additive), and verify the options are correct in scenario properties (I think its scenario properties, where you choose the texture of the snow).
If it is still not working, take screenshots of your height map tool pane, scenario properties window, or just a short video of your attempt.
Absolutely. Keep in mind, my response time can be a day, a week, or indefinite. I'm not as active in COH2 as I'd like to be at the moment.
Also, I recommend going through all the tutorials, tip of the week, and community tips, linked in my signature. And from the sounds of it, I highly recommend the Tip of the Week, Starting from Scratch. But feel free to ask away whatever questions you have.
So, in your modding hub, where you find your map, it doesn't say published next to it? What does it say, exactly? Screenshot of the manage tab where your map is displayed? What is the exact file name of your map?
On another note, I would love a video or thread that explains in detail how you actually make these beautiful maps? I must admit that I have no clue as to how you people pull it of!
Check out the links in my signature. Between all of those, and the 40+ pages of threads on the Workshop Mapping Discussion, there is easily a comprehensive guide to the entire process. Maybe we can get an admin to consolidate and pin a post with all the links.
From looking at the screens, and watching the replay...
I really like the detail of this map, especially the ruined buildings. The sector layout looks solid as well. The tile textures and SPLT's are blended well, everything looks sharp. I'll play it this weekend, and give a more detailed report.
As for feedback and criticism, don't let it get to you. Take it from someone who gets a lot of negative feedback (most of my maps are designed the break game balance, most people hate them). Some people have very specific map design that they like, and nothing else. The reasons don't really matter, and if they aren't willing to address the issues and bring forward possible solutions, then just write it off.
And for what it's worth (probably not much), you're a far better mapper than I am. Cheers!
