I'll try removing the light ents from the brush. Because at the mass driver when i compiled, even with the leaks, the water there was not buggy at all.
But is there any way i can leave the light ents in the water brush, even when one of the sides is a non-shader .jpg? Without causing a leak?
And, if not, how would i go about making the .jpg into a shader? Would i have to edit the map.shader file, or make a new shader file?
