Vray for SketchUp? - A Black Art?
-
I'm just starting to dip my toes into the whole rendering can of worms...
At the moment I am practising with SU Podium - mainly because it works as a plug-in inside SketchUp (not sure if that's true of the rest).
And luckily I qualify for a Educational discount on the full version...
As has been said - support is everything with rendering - modelling light on surfaces is a complex skill, and although Podium makes it a little easier, it is still an abstract process that does demand some 'hand holding' in the early stages...
I am happy, however, that the latest Podium news letter announces a set of pre-made lighting set-ups (as components), in order to help you fashion successful renders.

Ya-nee Bigstick's point is valid Podium is free as a trial version with the only restriction being the render size. Every month the trial ends and you renew it free, with any upgrades that are available. Bigstick is putting together a lighting package with from what I understand will be over 100 fixtures that are spec'd according to manufacturer, one needs just place it and select your bulb wattage.
I have used Kerky and it rocks, however being a lazy ex-vaalie, Podium is a one app build and render solution. Considering that it only launched in December, it has come a far way, and word has it that the future looks bright. Now with TBD the designer at the helm and he has always got a script up his sleeve for a tweak here or there, so I can only imagine what's next...internet streaming music using suave technology, while it renders (nothing like muzak for those paint drying moments)..realtime modelling maybe...hey see the new directX 10 products that are coming out, in a year or so over night rendering will be all but a relic of the past (at least thats how it seems)And for the record all free productive software rocks!

While I'm obviously a big fan of a certain render engine, I think it is bad form for people to suggest other render engines when a person has a request about another.
For instance, if someone has a question re: Vray... it should be left alone until someone that knows the answer is able to respond.
Telling a user that they should basically dump it to go to another render engine is not an answer, but a testimonial.
That said, in some instances I can see where it would be appropriate if the person specifically asks - "hey, if I want to quit using X software, what would you suggest to replace it?"
Vray is an exceptional render engine, and it takes time and effort to learn it... much like any other professional endeavor worth pursuing.
as my father used to say... "If it were easy, everyone would do it."

Hi everyone... i am a new user of vray for sketchup... and i am having a hardtime using the rectangular light feature
for some reason when i render the image the rectangular light renders as 'black' and instead of casting a light on an object it creates a shadow... does anybody know why? -
alley,
if using the physical camera try increasing the exposure or else turn of physical camera!!!

If you only want to have the rectangular light cast light but not be seen then set it to invisible in the light's properties.
Always use the physical camera!
-
Thanks for the quick answer... can you please tell me how to shut off the SU sun's GI ? i played around with the properties in the rectangular light option...such as the mutiplyer and with the invisible option. but when i render the light seem to not take effect... when i render with multiplier of 5 and then render the multiplier of the 30. the final image looks the exact same???
i have no idea why... could i be missing somthin in my settings? i just can't seem to get the light to work....in the image. -
I am having the exact same problem and becoming really frustrated.. From some reason whenever I have tried to render with the rectangular light.. no light renders.. I have tried playing with the intensity and playing with physical camera (off and on) and nothing seems to be working.. Can anyone help??
-
iirc the intensity of the sun in vray is approx 364. To turn off thee Sun you need to untick Default light in the vray system rollout. Now you should see the effect off the rectangular light. try them with a intensity value of 200 to start with.
-
if the vray physical camera is on and less value for your rectangular light. you wont really see them. physical camera works together hand in hand with the the vray sun. if you are using night scene better to turn off the physical camera. all lights (omni or point lights, emmisive and rectangular lights will appear)
if you insist in using the camera try lowering your fstop value, decresing the shuterss speed or even makign your ISO higher, but lo be careful because if your using ISO more than 800, the image will become noisier.
