vray sky visible in viewport?

[greysheep5]

hi!

as i kind of remember this was somehow possible back a few years/versions... can one enable a realtime sun/sky background in a perspective view? and if it works how, because i can´t get it running!? if i enable viewport background/show/use environment with an active sun/sky system, nothing is happening in the viewport?

asking for max design 2012 with vray 2.0.1 by the way!

any suggestions?

best regards,

christoph.

I think it cant show up VRay Sky, but maybe iam missing something.

[greysheep5]

ok, so it´s not possible i guess?

wasn´t there a script or something like that back in the days, maybe i misread those infos? i never tried it till last week so i have no clue if it´s possible or not! any other suggestions? and why isn´t it possible? would be cool and make the sun/sky system so much better, especially with the 2012 version and the kind of cool nitrous viewports. very nice for quick client presentation of architectural outdoor scenes to have a sky in the background...

best regards,

3ds max viewport support sky for mentalray, so I think it would be good. But if you use hdri map, you can show that.

search for Lele's old threads about his scriptpack, I'm sure he mentioned somewhere how to do it

[greysheep5]

well, than showing the vraysky in the viewport is a thing for the wishlist i guess!

@ DVP3D... thanks! and... well, i´m not sure if lele´s scriptpack would work with vray 2.0 and max 2012? but i am no scripting expert either. at least from what i see it´s from 2007 and for vray 1.5? kind of hesitating to try that. it´s not the end of the world not to have it in realtime, but would be a very nice addition to see the sky in the viewport. i mean, that´s what all this nitrous viewport initiative is about, getting the most out of your viewport in any way. don´t you think?

@ Jiri.Matys... yes, that would work for us i guess, adding a mental ray sunsky system for viewport previews. kind of awkward, but why not! but most of the time i would love to see the sunsky (vray´s) just for convenience in our lightning/rendering phase of the projects. we normally don´t use anything besides vray lights and materials.

Just switch on Vray RT?

[stef.thomas]

It does show in viewport, you just need to have show safe frames enabled.

[greysheep5]

i tried it one more time, and yes... thanks for the tip stef. it shows, just not in max 2012, at least with the nitrous viewports!

in max 2010 the sky displays (in the standard directx 9 mode). there it does not really depend on whether show safe frames is active or not. it just does not refresh instantly all the time which is no big deal. but all that may depend on the gfx card and drivers, in my case a gtx 460 2gb.

anyone got it running in 2012? and is anyone using other display modes than nitrous?

@dave wortley... of course, i could do that. and we do that all the time instead of rendering previews like we used to, at least for outdoor scenes. but it´s not really what i was asking for on the other hand...

update:

must be a problem with max design 2012, in 2011 it also shows up.. but maybe i am to dumb, i wouldn´t rule that out completely.

I think there is a problem with Nitrous and VraySky, I can't get it working either, with max 2012.

Does it work in DirectX/OpenGL mode?

hello vlado!

yes, it also works in max 2012 if i try it in directx mode! so it´s nitrous´s fault i guess... maybe you can fix that?

besides... one more question vlado:

how is viewport exposure control supposed to work? enabling vray exposure control in the environment settings doesn´t do anything to the sun being totally overbright in the viewport. it works best if i set the sun intensity to about 0.01 or 0.02, as we used to back in the day before we began rendering with vraycams and real exposure values. nowadays we normally have the sun multiplier somewhere around 0.5-1.0 which works quite good for outdoor scenes with the standard vray camera settings of f8 and 1/200 exposure. so shouldn´t the viewport in vray 2.0 reflect this if i activate vray exposure control? at least in max 2011 and 2012 (with directx, otherwise i don´t see any sun in the viewport) it stays bright white if i don´t lower the sun intensity to above mentioned values...

but maybe exposure control works, just not for the sunsky? i must confess i haven´t figured that fully out yet!

best regards,

christoph.

We are waiting for some additional info from Autodesk on whether we can make the exposure control to work in the viewports...
