Ok. Short : I'm making a garry's mod map using only hl2 resources. That means I can test it in hl2. So I'm making it. I'm compiling it. It has light. But again that stupid effect ... Light is dissapearing and appearing randomly in a building.
And the water doesn't render in game( you can't even "feel" it ! ) and I applied water texture only on the upper face of the solid. The rest of the faces are nodraw textured.
Here's the log. I won't be able to respond until maybe this evening, tomorrow evening or saturday.
Compile log removed
I don't know how this could be a leak when I have lighting ...
