I don;t know about the cmpwater but the gndtype is what sets the ground type for your terrain.
If you are having issues with your CBM being all black it is most likely because you did not have the "grid" box checked before you clicked the "make map".
I will try that right now...Nope....I just went through the "Something I did today" pdf 'from scratch', and got a perfect bmp on the first shot...without changing any settings...saved, exited etc..the re-opened the editor and made a second map.bmp and its all black...
Nope that is not it...
So here is my problem...
It makes a correct bmp on the first shot...after that the output is an all black bmp with "Grid Lines"....so obviously I will not use that in texsrc..
Why is the program incapable (for me) of producing second generation clip maps?
I wonder if this is a windows 7 issue...I further wonder why the terrain editor can not in its run time environment simply create a new bitmap and replace the existing bit map given we are in the 21'st century...and its quite stupid that a program that has gone through hundreds of updates, can't even create the texsrc directory and output bitmaps to it...extremely lame...lame beyond belief..
I could write a function in 2 minutes that checks for the existence of directory and if does not exist, creates it, and when the user chooses to update the core image or bitmap, creates a new bitmap from the underlying Graphic object of a control, and then supplants the existing bitmap with the new bitmap...that is child's play...in the coding world..
Its mind boggling stupid that the user of a program has to exit a program and create a directory structure to make the program work...and then have to transport a file to that directory and rename it...for the program to operate correctly...its astounding...beyond belief...
