--- Comment #30 from lubosz lubosz@gmail.com 2011-04-18 20:29:05 CDT --- The shader can't be replaced, it has to be removed. The buildings and mobs do not show up, when the shader compiles. I tried a minimal vertex shader, and they were also gone. Only when the shader failed to compile or was deleted, the black objects showed up.
