thanks a lot for your help zap

when i mentioned using a rayswitcher on the skydome, i was following a workaround described by jeff patton, where he talks about applying a bitmap to half a sphere that encloses the scene. it can be found on his blog.

i eventually got it to work

all i was worried about was trying to match the daylight system to that of the different bitmaps i had for different times of the day.

but with your help i am nearly there.

i am also looking for a best practice when it comes to gamma settings for p/graphic exposure and whether they should be changed when using logarithmic exposure.

the reason for this is that when i do make a render using a sky bitmap, the colour of the bitmap in the render is not the same as the original bitmap file?????
