I don't think anyone else uses it here.
All of my entries to the challenges have had some parts done using it.
Most of the months have involved me using an image editor to generate the base texture and then all of the icons on top are done with the app.
In December I used it additionally to generate height map elements by sprinkling rock height maps down over the base and then using DragonFlight to get that in 3D. The base was drawn with a pen, scanned, filled with textures and then the barrels, bags, skeletons etc were done on top with VDale.
Jan, I chose to do a 3D one. The gems and mounting lugs for them were placed on top with it.
Both Feb and March I am using a texture script to generate the base floor from texture layers and placing all the items on top with the app. If the floor were a dungeon then it could easily be done with it, I could have done this months floor using it but as I have posted in the thread the script I use is so easy that I am lazy enough to get that to do it instead. You will also see that the entries are usually quite high res and that its rendering all the items even if they are quite small. See the tray, plate and spoon in room 4 for example. The problem there is that I am so used to getting everything at proper scale that a spoon in a 125ft dungeon needs the res.
For sure, ViewingDale is weak at doing terrain. It can do it but it takes a lot of splat icons to make it look good. To be fair, there are not many apps which I would say were really good at that job either. The ones I could name are never mentioned here and cost a lot. So thats why I am trying to fix that with GTS where I can generate whole worlds at immense detail on DVD's.
The program is very effective where lots of items need to be grouped. Villages, cities, dungeons, buildings etc.
Maybe the best thing would be if you were to indicate what style maps you like or intend to make and I could suggest where it would or would not fit. I tend to use a variety of tools of which this program is but one. However it is a tool for which there are no other substitutes. You see a lot of planet scale world maps and village / city maps here. What you don't get are much regional maps or maps of cities where the city is small in comparison with the total map size. Or going the other way, you don't see many maps of small parts of cities, a street where the buildings are mapped. These are both areas where this app excels because you can zoom in from a city to street level or out to regional level. Not that it would exactly make the whole map for you in its entirety but it will zoom it such that everything is all in relation so that its easy to make one. If you start with a high res house and put a street of them together then it would render that street exactly for you in city scale and that street would be accurate in regional scale too. The point is that you don't have to do any work in those situations and therefore makes those maps more than just doable, but easy where usually they would be boring and quite tricky to get right. In any case nobody does them because if something changes in the city then the region map would have to be updated but with VDale thats done for you. I really should do a demo / tutorial about this sort of thing but lets get the iCon thing done first.
