+# Little Big Architect
+
+This suite is a set of programs, which purpose is to mod(ify) the Little Big Aventure 1 and 2 games. 
+
+They allow you to edit isometric sceneries, i.e. grid and scene files containing islands (exteriors) and rooms (interiors) in LBA 1. In LBA 2 only interior sceneries can be edited, because exteriors are in different format (3D).
+
+This program is released under GNU GPL license.

+
+## General information
+
+There suite consists of three programs:
+
+1. Factory - Editor for Brick and Layout files from LBA 1 and 2. It can read whole hqr files and single brk and bl1/bl2 files. Can export images into bitmaps. 
+ - Brk files are Bricks. You can find them in lba_brk.hqr form Lba 1 and lba_bkg.hqr from LBA 2 
+ - Bl1 files are LBA1 Layout Libraries, you can find them in lba_bll.hqr 
+ - Bl2 files are LBA2 Layout Libraries, you can find them in lba_bkg.hqr 
+ - Latest version of LBA Package Editor unpacks all these files with appropriate extensions (except for bl1/bl2 - unfortunately version 0.10+ unpacks them all with "bll" extension)
+ - To display a library file a Brick package must be loaded. If there is a single Brick loaded instead of a Brick package, you will not be able to see the Layouts even if they are opened.
+
+2. Builder - Editor for Grid and Scene files from LBA 1 and 2. Needs Brick, Library and Grid files to be loaded at the same time (lba_brk + lba_bll + lba_gri or lba_bkg). You can set paths to original Lba files in the View->Settings menu. It can export rooms/islands into bitmaps.
+ 
+3. Designer - Tool for creating complete HQR packages from separate Grid, Layout, Grick and Scene files. The generated HQR can be used in LBA 1 game directly. The program cannot yet create files for LBA 2, because of the unsupported 3D-Scene format.
+ 
+## Known issues
+
+#### Builder:
+ - It sometimes happens that the program will crash without reason when following specific steps:
+   1. Single Bricks selection mode has to be enabled.
+   2. Go to Hand mode.
+   3. Go to Placer mode and change the selection mode to "Select by Layouts"
+   4. The program will crash when you try to click anything.
+   
+ I've got that report from one person only (it happened to him many times), so I suspect it might be a machine-specific issue, because I can't reproduce it.
+
+ - 3d helper may be drawn incorrectly near the background net.
