| OK, I have found an answer - so for anyone else in this situation here it is:
The intensity of the shadow (e.g. how black it is) is NOT controlled by alpha or transparency.
It IS controlled by GLOW.
Give the shadow catcher a pure white glow and you get lighter shadows. Reduce the glow and the shadows get darker.
I have not tried different coloured glows yet - I will leave that to you.
Happy answers.
Cheers. |
