Sorry so late
Things got busy past couple days
Here are some step for cutting height and texture maps using IrfanView http://www.irfanview.com/
In my case I created a 2048x2048 terrain using L3DT and cut it into four 1025X1025 (you overlap the edge pixels)
Create 2048x2048 terrain in L3DT
Export height and texture maps
Create cut 1025x1025 height and texture maps using IrfanView.
Use Edit->CreateCustomCropSelection
In dialog enter X-Coord, Y-Coord, Width and Height
example: X,Y ( 0,0 ) wid,hi (1025,1025); then click āApply to imageā
Then Edit->CropSelection
Then File->SaveAs new file name
Do next areas as above:
File->ReOpen, and begin steps to crop another
example: X,Y ( 0,1024 ) wid,hi (1025,1025); then click āApply to imageā
then crop and save as before.
Then cut and save
X,Y (1024,0 ) wid,hi (1025,1025)
X,Y (1024,1024 ) wid,hi (1025,1025)
If you want to see how I did texture splatting, Iāll have to add that later; but you use L3DT to write out all the names of the textures used (grass,rock,sand, etc) and produce a couple files that map each type of texture into each color channel. You copy the individual texture images and channel mapping files to where you want them, and cut them up the same way.
In Panda you have to add them in as different āstagesā and set a shader to do the āsplattingā of them together.
