Hi,
I have a set of vector grids in FGD, I want to overlay these on some rasters. I have managed to achieve this but I want to make the grid slightly transparent, I have tried adding 0.4 after the third colour value but that doesn't seem to hold when I run it through VectorOnRasterOverlayer. Has anyone got any other ideas on how to achieve this?
I have attached my workbench so far.
Thanks

The VectorOnRasterOverlayer has an Alpha value parameter - try adding your 0.4 value here

Thanks for the help, unfortunately that has not worked. :(

@egomm is correct, the alpha settings control the transparency of your polygons. Note that the rasters need to have an alpha band. See workspace for example.
Alternatively for more control you can use the MapnikRasterizer.
