I've read the BloodRayne fog tutorial but I don't want a 'real fog' I just want a basic fog but with a cloudy texture with scrolling. <br /><br />I copied the 'basicfog' entry in fogs.mtr: <br /><br /><div class="codetitle"><b>Code:</b></div><div class="codecontent">fogs/mytestfog<br />{<br />   fogLight         // tell the engine it is fog and not a light<br />   noShadows<br />   {<br />      map      _fog   // the internal fog image<br />      colored         // take rgba from entity shaderparms<br />   }<br /><br />(and added this from the tutorial:)<br />   {<br />         blend filter<br />         map       lights/cloudscroll.tga<br />             scroll       time * 0.02, 0<br />   }<br /><br />}<br /><br />Which didn't do anything. So I canabalised more from the tutorial:<br /><br />fogs/mytestfog<br />{<br />   blendlight         <br />   noShadows<br /><br />   {<br />      blend add<br />      map      textures/lights/squarelight.tga   // the internal fog image<br />      zeroclamp   // make sure it doesn't bleed over the edges<br /><br />      //colored         // take rgba from entity shaderparms<br />   }<br /><br />   {<br />         blend filter<br />         map       lights/cloudscroll.tga<br />        scroll       time * 0.02, 0<br />   }<br /><br />}<br /></div><br />Now this made the cloudscrolling work but the fog was replaced with blackness. I used squarelight.tga because I figure it already has an alpha channel, allthough when I looked at it in photoshop it just had 'background' but I figured it was because it had been 'flattened' like I'have read in a few tutorials.<br /><br />Also in doomedit the picture window in 'light editor' was black.<br /><br />Can someone please tell me how to have a standard fog with a cloudy texture that scrolls.</div><br><hr><br/>
