very good star Gate, you are the materials wizard, i prefer to make the sphere z=0.2.
there is a problem with:
BaseTex = LoadImage(#PB_Any, GetPathPart(ProgramFilename()) + "texture/concrete.jpg")
the GetPathPart(ProgramFilename()) return the "C:\Documents and Settings\applepi\Local Settings\Temp" and not the folder of the code, so i have used instead "BaseTex = LoadImage(#PB_Any, "texture\concrete.jpg")". i will check it more later since now i have too much back muscles pain.
also the 3.bmp, 4.bmp: the images server store it as jpg so the user needs to convert it to bmp via irfanview
but the example are very good. thanks
here is the picture, if there is something missing tell me.


EDIT: regarding the problem of GetPathPart(ProgramFilename()) it is discussed and solved here: http://purebasic.fr/english/viewtopic.php?f=13&t=63576

The image looks fine. Hope you'll get over the back pain soon.

Here are three other water scripts. Add it to the existing 'stargate.material' file.

I am having a problem downloading two of the texture image files.

The files:
3.bmp
4.bmp
do not have links that lead to the images.

[applePi]

@ElementE: just right click on the small picture and save as (either 3.jpg or 3.png depends on the browser) then open it in paint or irfanview and save it again as 3.bmp, 4.bmp.
@DK_PETER: thanks for the additional materials, the material water3 are impressive, it reminds me of that empty glass sphere which have sparks and lightning inside due to high voltage.
