Hi,
Making great progress with Vray Beta since 2 days ago when I gave up on Vray Free but I have a quick question on lighting which may be something very obvious.
I am working on a VR of a bathroom (current job for a client but the purpose of this is to produce a test VR - client will not see this VR)
It has about 12 recessed downlights with lots of glass and reflective surfaces etc so even though it is a small scene, it is calculating very slowly.
I am wondering about the downlights. Currently I am using standard viz4 photometric area lights, with a target distance of 3m (600mm under the floor). For the distribution, I have it set to 'web' and have chosen an IES file (each light is an instance copy of 1). Maybee I have answered the question myself but here goes....:
Should I be using non-photometric light sources in VRAY without an IES file considering my secondary bounces are using photon maps?
My answer to myself is to use standard lights (not photometric) without the IES settings since both of these things will slow the IR calculation down. Can anyone confirm that this is right/ wrong?
Anyway, my scene continues to process the prepass VERY slowly even with all glass hidden so while that generates for each face of the cubic VR overnight, I wonder how much time I would save with this simple change in lighting.....Man I hope i remember to save the IR map in the morning!
MY materials and reflection settings are very crappy at the moment but I am hoping to be able to make adjustments to these once the IR map calculations are saved to enable some relatively quick fine tuning.
One last point. My aim is to match the image quality and speed I used to get out of Lightscape 3-4 years ago. Looking at this forum makes me realise there is potential to push things further, but at great sacrifice to render times. Will light mapping be the answer? is this the closest thing to how lightscape calculated the lighting solution? I am eagerly waiting this next step
PS: Apologies for the lack of sense of this post. I basically havnt slept for a week after really screwing up a big job
I am detirmined to put myself through hell in order to make progress, move on and eventually make up for my clients dissapointment.
