Ding, ding, I'm bot!
Ahahah not at all, don't worry about naked guys stuff!! Thanks for watching! :)
Sorry, I won't have the time for this, please check the forums/wiki mentioned in my previous post, you will find answers!
Hi, so to resume in this case I firstly gather and prepare my own textures for the map editor (i.e. using Gimp then the material editor) - when it's done, back in the map editor, I select the Primitives category (n°9) to choose the Plane tool; there I can specify my texture, set it how I want, set some properties to the surface then put it in my map. Here I just have to place it where and how I want. Not really hard but it can takes lots of time. For models and more help I suggest you to search on the great Frictional Games Forums (tons of things there, awesome community contents, etc.) and don't forget to read the Wiki too - it is really well done and covers everything, maps, models, scripting, etc. ;) See ya!
Don't worry I take my time! I'll write some news very soon to give precisions on what is already completed at the moment.
Thanks, I'm working a lot to get a particular/moody atmosphere on some maps, I'll upload more screenshots in the future - but not too much, I would like to keep some surprises. ;)
