Hi bpahe.You are omitting texture names:TextureDataStart label wordtexturemark_0 label wordVTPTextureName VTPTextureType 1, 0, 0, 4texturemark_1 label wordVTPTextureName VTPTextureType 1, 0, 0, 4texturemark_2 label wordVTPTextureName VTPTextureType 1, 0, 0, 4texturemark_3 label wordVTPTextureName VTPTextureType 1, 0, 0, 4texturemark_4 label wordVTPTextureName "3" ;Coniferous ForestVTPTextureType 1, 0, 0, 4texturemark_5 label wordTextureDataEnd label wordEven if you are not using them, you need to declare something, or the thing won't compile. Try this:TextureDataStart label wordtexturemark_0 label wordVTPTextureName "3"VTPTextureType 1, 0, 0, 4texturemark_1 label wordVTPTextureName "3"VTPTextureType 1, 0, 0, 4texturemark_2 label wordVTPTextureName "3"VTPTextureType 1, 0, 0, 4texturemark_3 label wordVTPTextureName "3"VTPTextureType 1, 0, 0, 4texturemark_4 label wordVTPTextureName "3" ;Coniferous ForestVTPTextureType 1, 0, 0, 4texturemark_5 label wordTextureDataEnd label word================You can sometimes track down BGLC errors by using a DOS window. WindowsXp hides it's window as "cmd.exe", and is found in the "C:WINDOWSsystem32" folder.I make a project folder that contains TDFMacros.inc, TDFHeaders.inc, BGLC.exe, CMD.exe, and my BGLC code files. I'll drag'n'drop the BGLC code onto the BGLC Icon to compile.But if that doesn't work, I'll open the CMD and within it's window I'll type:BGLC mycode.asmThis will now give a list of the errors, and the line numbers they are on!In WindowsXp, notepad has the view option of a status bar ( when not in wrdwrap ). Now you can easily go to the line of the error, and try to see what is wrong.Dick

By making the change I noted above, and adding the lines at the start of the code:include TDFMacros.incinclude TDFHeaders.incThe code compiled just fine.BGLC.exe, TDFMacros.inc, TDFHeaders.inc, and your ASM file must all be in the same folder.I'm attaching the code as a txt file, that can be drag'n'dropped right onto BGLC's icon to compile.================But what it is compiling is beyond my comprehension. You're mixing widepoints with poly points, in a polygon. You probably need to review the FS2002 terrain SDK, so you have an understanding of the different data structures. The code isn't usable as it exits... and I've never seen LWMDraw produce anything like that, before.Dick

Well, I'll be ding, dang, donkey! I didn't know about that dern status bar thingy!You-all musta been hold'n out on us'es!:-lol

Hi HansThe first problem I see in your generated VTP source file is that you've tried to place both VTP Line format and VTP Poly format into the same file and I don't believe both formats are compatable within the same file. I probably should have put an If statement into the code of LWMDraw to deal with this issue so that a user can only select one or the other formats but I didn't even think of that although I do recall explaining about these two formats within the "Menu and User Information" menu.This is the Polygon format:VTPPointXY2 4912, 11696VTPPointXY2 4979, 11730And this is the Road/Line/Shoreline format:VTPWidePoint 4857, 0, 11819, 0VTPWidePoint 4867, 0, 11904, 0The next problem I found is again related to the "Menu and User Information" menu. Within the VTP Properties tab you'll notice one selection combo-box for Road/Lines/Shorelines and this is a required parameter for Lines or Polys. Please note that this combo-box places the selected option onto the "VTPTextureName" lines and if there is no selection then those will be blank and the file will not assemble properly.You can copy-n-paste your selection, ("3" ;Coniferous Forest), directly from the optional landclass combo-box into the upper roads/lines/shorelines combo-box and upon generation of the source file all five VTPTextureName lines will be filled in with that value or you can use Dick's suggestion and simply type "3" .I hope you've found this helpful along with Dick's excellent suggestions. I also hope you'll read and look through the text of the help files within LWMDraw as well so that you'll have a better understanding of the process as well as some of the limitations that can or can not be used within these source files.Thanks for your post.Ken

Hi everybody!Thanks for all replies! Well, first of all, the first thing I did after downloading LWMDraw was of course to go through both the tutorial, and the quick-start guide. I

Hello again!Ok, this is it:I followed the examples above, and now the produced VTPsource.asm looks like this - it compiles nicely and works excellent in FS2002!

Hi bpahe.Hooray! :)Read the SDK and get some more info by reading old posts here about VTP and LWM. In a few weeks you'll be making all kinds of things.Dick
