Hello everyone, 
I am currently doing some Raster Algebra Analysis with QGIS. When I tried to create staged Raster buffers with the r.buffer function from the GRASS toolbox it always gave me a nodata value ‎for everything outside the defined buffers. I tried to set a final buffer stage about the size of the max Work-enviroment size (about 50 kilometres).
 That works till up close to the borders I need, but whenever it get's so close one pixel of the buffer would technically overlap the boundary it just makes the entire outer buffer stage nodata. 

Is there any direct way to just have it fill the entire space set by the workplace boundaries outside the defined buffer stages with a value?

Thanks in advance
Jeffrey Rhodes
