Hello!
There seems to be a bug in ATI OpenGl drivers when using uniform arrays.
For e.g. the uniform array "float arr[3]" I have found that
getUniformLocation("arr") returns an error while
getUniformLocation("arr[0]") returns the desired value.
This is in clear contrast to the glGetUniformLocation documentation,
where it says:
"... Except if the last part of name indicates a uniform variable array,
the location of the first element of an array can be retrieved by using
the name of the array, or by using the name appended by "[0]"."
Has anybody else experienced this issue? I expect no workaround will be
implemented in OSG, so I'll have to do without array uniforms?
If nothing else, this should warn anybody searching for ATI and array
uniforms...
regards
cm
