Vray Sky and Environment Question

[Dave Buckley]

In house RMJM team??? Cool, i was down at the RMJM london offices the other month and was amazed by the visualizations on show all around the office, i was wondering who created these things

[Dave Buckley]

weird, i have the scene setup with sun, sky and plane lights in windows, physical cam, lighting looks good.

 

however, if i remove the plane lights the scen goes a lot brighter??? surely if i am taking lights out of the scene it should go darker?

[Stephen Thomas]

so if i'm using a vray sun, i do not need it checked, and also if i am using vray sun and decide to change the intensity in the scene, it becomes not pysically correct right?

If you're using the physical camera you should always have it set to 1.0 and adjust your exposure settings on the camera.

Can't take the credit for all of that, glad you liked it though.

here is the tests, you'd expect the inclusion of plane lights even at multiplier 1 to brighten the scene, although they could be doing, perhaps its just the colour that i have them at giving the more orange tint and therefore making it look darker. am i going mad or have i been looking at it too long

if you are using plane lights with phys cam you are going to need to jack up the intensity alot. anywhere between 10-30 depending on camera.

cheers stef, the scene is actually an evermotion scene that i am tring to break down and understand why they have setup it up as they have done.

 

what i notice in a lot of interior scenes is that, the background plane are often done by adding an image to a vray light material?? i can't figure out why this has been done either because there are also plane lights in the windows, surely these are providing the environment light???

 

and if they are then surely the sky and the environement overrides are not needed either

 

there's a lot i would like to say about this subject, but instead, i will bite my tongue and just say, i don't recommend using evermotion scenes to guide your work

As someone that's not using VRay but considering picking it up and about the validity of the evermotion stuff, I've been wondering about this exact thing. Thanks for speaking up Brian.

[Dave Buckley]

well the conclusion i have come to is that there is no logic behind how they have set there scenes up. it just seems to be a random combination of lights to make whatever looks good. some of the lights they have in there scenes could be easily avoided, and also there doesn't seem to be any consistency between scenes. there exposure settings are also far from real world which i guess defeats the object of using the sun and sky in combo with the physical cam

 

anyway this is what i came up with after deciding myself not to use those scenes as guidance

 

personally i don't think the use of plane lights is that necessary to get good illumination in the interiors, if you can get the exposure right on the phys cam then just the sun and sky work

 

in this image, i have plane lights, sun and sky and phys cam the plane lights have a multiplier of 1 so basically i suppose i could take them out, but i heard it they do help to give a cleaner GI solution, and the colour changes also if i take them out.

no need to bite the tongue brian, i was merely interested in how they went about setting there scenes up, don't worry my to main resources (not so much for vray - although still good) are your two books.

 

perhaps the next one (if there is) should be Architectural Visualization with 3DS Max Design 2009 and VRay Advanced to Expert

evermotion are one of the worst things to ever happen on planet earth after WW2 imo.

[Derek Forreal]

oh come on, they're not that bad are they?! ok, so a lot of renders look the same nowadays, but EM did take rendering to a new level at the time (and probably still do - haven't really looked at their stuff in a while)

 

just because their 'look' has been copied (or at least attempted to copy) so much, doesn't make them

by the way, i've got nothing to do with EM. but if i'm a better artist today it's partly thanks to them and i have no problems saying it
