that's really not how things work here, mate. please delete and ask for help about heightmapping on modding forum, then redo it when you have some concrete stuff
If you actually read the rules you would know that you can't delete a thread and that's why you usually don't make one until your project is at least 90% complete and you are 99.9% sure it will be released. And that it's strictly forbidden to post threads when there's no progress at all or too little progress.
