Fog light misbehaving - fog shadows disappear
:banghead: I have a fairly large scene made in Maya 4.03 where a hole opens in a surface and a fog light (spotlight) shines through. When I first make it, everything works fine, and I get a nice coloured fog beam shining through the hole in the surface.
After a few changes to other parts of the scene, I find that the fog no longer takes any notice of the surface or of the light colour, and I just get a white cone the shape of the spotlight beam. I've tried deleting the light and making a new one, but that doesn't work. I've checked that the shadow casting and receiving properties of the light and the surfaces involved are switched on. The light does actually cast a shadow, it's just the fog that won't co-operate. The only way I've found to get out of this problem is to go back to a version of the scene saved before I put any lights in and start again from there. But I've done too much work now to go back that far, and I promised the client a rough render today... Please, please, can someone tell me how to fix this. |
Hmm... Quite odd... Tried exporting everything else but the lights to another file and then create the lights again?

Did u rescale the spotlight at all?? |
:banana: Hi guys,
Thank you so much for your help. First of all, I discovered that I had been working on the wrong scene! Eight hours struggling with it, thinking that something had gone wrong again - AAAAGH! So I managed to get the job out, although it was an all-nighter. The scene causing the trouble was one where I had tried to do some light linking and got it disastrously wrong - hence the strange fog lights. Exporting everything except the lights did solve the problem with this scene. I deleted all the lights and exported the rest to a new file, and now fog lights work properly. To quote Benny Hill: "Learning all ze time". Alex: is there a reason not to scale spotlights with fog? I find I have to do that to get the fog to go far enough down the light beam. Thank you again, both. I'll know how to get out of that one if/when I hit it again. Julian |
