Rendering large exterior animation

V-Ray V-Ray for 3ds Max General

Hello all,

wondering what would be the rocommended settigns for rendering large flathrough over the developement with loads of trees?

do you reckon classical LC and IRRAD precalc and AA at 1/16 0.008noise would do?

how so i estimate there is enough LC subdivs for computation of the whole scene whole precalculationg light cache?

Would you recommend precalculation IR with camera path checked to avoid having to choose multiframe incremental?

there r no moving objects in the animation, the only thing moving is the camera.

thanks for your help and suggestions

best regards

I really think it would be worth testing out the vrayambientlight, although not having used it much, it might be a gamble.

ha :slight_smile: gamble is something i cant really afford in these timescales :slight_smile:

can anyone share a good setting please? or comment my idea of settings please?

Thanks a lot

As was said, VrayAmbientLight is probably the way to go, we used it recently on large-scale 26x17km landscape visualization. After few modification to vraydirt map ( mainly radius - set to high value ~>100m), it was usable as a very good fast fake GI alternative.

could you post some images ?

Maybe later, cause I’m off from the office for a few days.

For big externals I tend to go with BF with low settings instead - it’s a bit more reliable than LC. Tend to like i’ve done more than 2…

Either way the IR map should be doing most of the work.

I’ve not gone up to 1/16 - tend to stay around 12 tops which does produce some slight noise but it usually gets hidden under a bit of post work.

We also used IR+BF before SP4, it`s very reliable, but at scenes with a lot of tiny details and objects there is still possibility to get nasty flickering if the settings are not `upped` enough. Not to mention precalcing IRmaps and so.

We `gambled` with AmbLight - and it proved worthy. The speedup of scene rendering was >50% , mainly because there is no precalc of indirect lighting. Not to mention no flickering at tiny details at all ( all as expected .. ).

Of course AmbLight is restricted in the terms of being `fully` fake GI alternative, but if it will get the ability to sample the environment, then it will be again a lot more close to `real` fake GI.

ok you must be back by now :slight_smile:

can we see some examples murko-sk?

Hello,
sorry for the delay, I absolutely forgot this thread :roll_eyes: . Here are some thumbs for example :

Wow - first one looks fabulous!

great work!
this is a really old post :)))

wow, looks awesome

14

Very good…

Can you give some info about Ambient Light?
What is the diference from Environment Skylight? Is it some kind of a environment skylight that can produce direct lighting?

16

its very useful when cheating with ambient oclusion :slight_smile:
basically a vray light, where you can apply a dirt shader and control the amount of AO (sort of)
in heavy distantexterior scenes, you can use it together with vray sun to create illusion of GI with drastic rendertime improvements compared to GI
it also doesnt flicker if you set it up well :)))
