Known Bugs & Issues

Since I have developed Forester on my own computer (500 PIII, 128Mb RAM, Win98 English Version, etc) it is quite possible that there will be problems on systems with different configurations/specifications.

Issues List

DirectX Preview

• Produces error with some graphics cards when using Hardware Acceleration. I want to fix this issue, but I need to know which cards it works on and which it doesn't. Please fill out the survey to let me know if it works on your system or not. NOTE: If it doesn't work in 24-bit colour screen mode try changing to a 16-bit mode (or vice versa). I've had reports that this may sometimes 'fix' the problem.
• Crashes under Windows NT - unfortunately DirectX is not fully supported in NT so the preview is unusable. You can disable the preview (Tools/Options) to use an older style wireframe view, but I am no longer supporting this feature.

'Error Finding Applications Folder' and errors in 'LoadLibraryBranch' Module

• Forester has stored the wrong folder paths for the Object library folders. This information is stored in the registry and is recorded the first time Forester is run. However, if it gets the paths wrong this first time then it will keep searching the wrong paths until the registry values are corrected.
   
  The simplest way to fix this is to delete the following key from the registry (which will force Forester to re-store the paths the next time it is started):
   
  HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Forester\Filepaths
   
  You can either delete this key manually using the Windows Registry Editor, or I have written a small utility (5Kb) which will delete it for you. (Close Forester, Run the utility and then re-start Forester).

'Invalid Procedure Call or Argument' - Error 5 in Module 'StartPOVRay'

• Make sure that the POV-Ray EXE file path is set correctly in the Forester Tools/Options menu. This is the POV-Ray program file that Forester 'runs' when it starts a render. It should be something like "C:\Program Files\POV-Ray for Windows v3.5\bin\pvengine.exe".
• Depending on the operating system (95/98/ME/NT/2000) some people experience this error when Forester tries to start POV-Ray to render a scene. This is usually fixed by telling Forester to use another method to start POV-Ray. In the Tools/Options menu try changing the 'Method Used to Start POV-Ray' option.
   
  If this does not work then POV-Ray will have to be started manually. This is not too much of a problem. In the Render window un-tick the 'Auto-Render' option. To render a scene click the 'Create Script' button - Forester will generate the POV-Ray scene files as normal. Then, open POV-Ray and click the 'Sel-Run' button. Navigate to the Forester/Scenes folder and open the Forester.ini file (NOT THE Forester.pov FILE).
   
  NOTE: For rendering an animation all the frames will have to be generated by Forester in advance. The POV-Ray 'Queue' function can then be used to render these multiple frames.
