I think ive found a problem. I usually compile the wrapper and add the dll reference to project. This workd when i use A8, but when i went back to A7 to try out some shaders, (i only have A8 free)i find it only works if i add the AW folder to the project, not as dll. I tried all the examples out and that is the result i got. Using A7_WRAPPER as conditional i have to remove the dll reference and add the AW folder to the project. Without A7_WRAPPER as conditional the dll works fine. Hope this makes sense my explanation.
