Ok, heres a little scene I have been working on, and need a little help with;
I’m using mentalray/final gather to render.
I have a Daylight system set up coming in from the left,
And a photometric ies light used for the lamp. (with an additional, normal, spot light in the same place purely used for volume effect, ver Parti_Volume…apparently photometric lights don’t work with volume shadows according to this ).
My mentalray render settings are just on the defaults (with the exception of the volume light set)
My main problems are three fold, and I suspect they are mostly to do with fine-tuning the render settings themselves;
The image is too grainy, particularly showing up badly around the newspaper. I have tried rendering with Noise filtering on max, and this actually makes no difference.
The blotch’s of light on the table to the right.
The fact the volume light for the lamp is showing up over the lamps cone itself. Given the light starts from inside, this naturally shouldn’t be happening. Its almost like the cone is transparent, but its not. (metal shader, black).
Any help with any of these issues will be most appriciated.
