Shader Development Studio Problem

Hello,
Recently I decided to try out Mali Developer Tools, which look very promising.

Unfortunately I have a problem with Shader Development Studio.
When trying to make SimpleTest Project (from the User Guide) while rendering the shader effect
the Shader Preview shows a triangle instead of a square shown in the Guide.
In general, it is not surprising, since the option VERTICES in Shader Attributes View has by default  three
vertices:
-1.0 -1.0,0.0,1.0,
1.0 -1.0,0.0,1.0,
1.0,1.0,0.0,1.0,

The problem however is that there is no possibility to add additional vertices
(when choosing the option USER_DEFINED). You can only change the three given.
Changing the geometry in Shader Control View do not bring any effect, always showing three vertices.
Even when using a Shader Examples from Mali GPU Shader Library shaders are applied to that triangle.
The shaders themselves are working (changing color, texturing, etc).

Plugin has been tested on the following configurations:
Eclipse 3.6.2
  • GeForce 9600M GT Windows 7 64bit
  • GeForce GTS 250 Windows 7 32bit

All necessary OpenGL extensions are present, Emulator and Offline Shader Compiler are installed and work.

    Hi all,
    I have had the same issue. And I think i know the root cause.
    Looks like it's happens then you have non "." (point) separator in your system for float numbers. For me it was "," (coma).
    So just set US locale setting.

    For plugin developers: Please dont use system separator. It happens inside of com.arm.mali.shaderdevelopmentstudio.callscript.Geometry. The java.util.Scanner throws java.util.InputMismatchException then trying to parse float number.
    Sorry for my English.
