I was planning to make a global orthographic map, that would show country borders and oceans. Therefore,i followed this method which plots a map similar to my requirements. However, i modified the codes so that the map is centered on Asia:
+proj=ortho +lat_0=10 +lon_0=90 +x_0=0 +y_0=0 +a=6371000 +b=6371000 +units=m +no_defs
There has been a similar post regarding this problem, where it was suggested to use uncheck the simplify geometry options in the layer rendering, but that didn't work for me. I'd be really grateful if someone suggested me any way to properly project the ocean layer in the globe, like in this picture: Thanks in advance.
