MPEDIT doesn't show the current properties of entities. It always shows the currently active properties from the status bar, basically, it shows the settings that will be applied, not the current setting of the entities.

(And also note that MPEDIT only applies the settings when hitting OK if the checkbox for that setting its set)

A different way to check things is also just to hide the relevant sheet. Expecting everything to be on BUILDINGS?, well, then simply hide that sheet and see if anything remain (Or hide all sheets but that one, which is a nice feature int he sheets dialog I like to use)

Hiding all sheets but one is also nice when working, because that means you can do selection "by all" to grab all the relevant entities instead of trying to select the relevant ones individually

Some of your buildings are on the buildings sheet, but a lot of them are on the SYMBOLS sheet instead. Looks like all the ones not casting shadows in your image is on the SYMBOLS sheet.

The best tool to check this is always the LIST command. It reveals all the needed information.

These values and their use can be a bit hard to understand, so let me throw in some explanations and see if that clears things up. Let me know if things still doesn't seem to work as expected after taking this into account.

• Inclination is only used for roof shading, not the shadows cast from the buildings. No matter what you set for inclination, the length of the shadows will be the same, but (assuming you use a city style that supports shading - most do) you should see a bit variation in the shading of the roof. This is combined with the steepness of the roof, so the actual effect can vary, but you should see parts of the roof getting lighter/darker when changing this, but it will have no effect on the shadows cast on the ground by the building
• The blur/transparency setting are only for dungeon lighting. It is possible to use in city maps as well, but it will have no effect as long as you don't have any configured light sources in your map, and the appropriate Point Light shadow effects set up on your sheets (which are not in city maps by default). Without this setup, these settings do absolutely nothing for your map.
• Azimuth, on the other hand is directly used by the "Wall Shadow, Directional" effect, IF the effect is configured to use global sun instead of a fix angle (It usually is). Thus this setting will change the direction of the shadows cast by the buildings.

That's a limitation in how computers store numbers.

Basically, because computers use binary internally to represent numbers, there will always be errors in precision for decimal numbers. Computers store these numbers smartly, so if the number before the decimal point is small, you get more precision, but since you have a somewhat large number (5 digits), it means that you loose out on precision on the decimal part. (Float can store 7 digits precicely)

There are different data types that can be used that offer different degrees of precision. CC3+ is using a float type to store these numbers, which is less precise than a double, but also uses less memory. Float was selected for the code back in the day, because it gave the best memory performance compared to the needs for very high precision.

In short, this is just how computers work.

If you are interested, here's a code example that shows exactly what happens:

#include <iomanip>
#include <iostream>
using namespace std;

int main() 
{
 float f = 18888.62110;
 double d = 18888.62110;

 cout << endl << "18888.62110" << endl;
 cout << "Float: " << setprecision(10) << f << endl;
 cout << "Double: "<< setprecision(10) << d << endl;

 f = 18.62110;
 d = 18.62110;

 cout << endl << "18.62110" << endl;
 cout << "Float: " << setprecision(7) << f << endl;
 cout << "Double: "<< setprecision(7) << d << endl;
}

Output:

18888.62110
Float: 18888.62109
Double: 18888.6211

18.62110
Float: 18.6211
Double: 18.6211

When CC3+ is installed, it installs 2 folders, the program files, and the data directory.

The program files folder is extremely tiny (less than 50MB), and is always installed on the C drive. (c:\program files(x86)\ProFantasy\CC3Plus)

The data directory is installed to wherever you pick in the installer.

You can move the install folder away from C, but I do not recommend messing with it. It is extremely tiny, and does not take any real space at all on a modern drive, even if you have a real old tiny one.
