Vray and Maxwell produce quite similar results. They are both far ahead LW or Artlantis.

Misinformation I guess! Why do they choose Autocad too?

hi all,
1) look at the poll - only 32 votes (and only half of those want it)
2) high poly models - to make photoreal renders, scenes (models) have to be prepared accordingly. once you're through with placing furniture, accessories, plants, filleting edges etc, a typical residential scene could have anywhere between 200k - 1m polys (many have more). the ac engine simply isn't ready for that. just click on a 3d tree in the object picker and depending on settings your pc may crash there and then let alone if you want to create some instances of one.
3) even if ac could handle polys, there aren't many tools for creating them in the first place. does anyone here use ac for furniture building (other than square furniture!)?
in short, 'photoreal' renders out of archicad just look too bare. this is why the sketch engine is the preferred one.
IMHO before archicad gets vray (or maxwell for that matter) it should have a robust modelling toolset.

"v-ray best rendering engine!!!" (sorry, don't know how to use quotes)
vray isn't the best, it's the fastest. have you seen the maxwell render gallery lately?

"I seem to recall having heard the same about Maxwell.
Waht is the real difference betwen Vray and Maxwell?"
maxwell is an unbiased renderer = takes into account ALL light interactions. this is why render times are so long
vray is a biased renderer = approximations are made. most approximations are controllable but can take ages to tweak, maybe longer than it takes maxwell to render. also, you are able to adjust maxwell lighting after the render is complete avoiding the need for rerendering
just my 2p

polygons are not a problem for archicad. it can easily handle over 1milion poly scenes. the lag you are geting in 3d is only at rebulding the scene. it comes from gdl interpreting. try to save gdl objects as binary and wou will see the difference. I had many scenes over 1 million poly all created in ac and had more problems after exporting in max than in archicadok, this sounds good, but how do i "save gdl objects as binary"?
Filleting is not a problem in vray - it has an "edge texture" feature that fillets at rendering time without creating any more polysi tried this when i first used vray, but gave up on it because it was also filleting edges that i didn't want filleted. i will be experimenting with this again over the weekend.
you don't need to create furniture in archicad. also if you are working in architecture and not interior design you don't create furniture in max either. you just use professional furniture models. Do you have the time to model even 1 piece of detailed furniture when you are in fact selling the house? I don't think soi only model projects that i go on to build myself, so while the houses are being built i do have the time (and i also enjoy) to model some of the furniture that we will include in the finished house. this helps us to sell the house with the furniture included and make money on the furniture too.
vray is the best rendering engine for architecture - this is my opinion.don't get me wrong. i too am an avid vray user and i think it is an excellent renderer. i don't use maxwell, but i think if you compare the very best vray renders and the very best maxwell renders, maxwell produces truly lifelike images. when i said vray is the fastest, i meant the fastest 'photoreal' render.
It is not the fastest - i think artlantis does that job.
as for the quality you should also check vray gallery. I can tell you for sure that for any good software like maxwell or vray - quality is not an issue if you know how to handle it
about the time to tweak - if you know what the settings are for you need just 1 minute or 1 click for activating a preset. If you don't know what wou're doing you need to read the manuali'm getting decent results a lot faster nowadays, but i still think that you have to play around with quite a few settings if you want to get the most efficient render, which is kind of a contradiction in terms. can you honestly say you haven't spent many hours re-rendering the same image trying to get that perfect render?
vray also has an "unbiased" tracing engine - it is called PPT (progressive path tracing) - and you can use it to let it render an image until you are satisfied with the result. however nobody uses it because it is just as slow as maxwellyes, i have tried PPT but this does take a very long time... this is my point, the most accurate (and therefore the most realistic) renders take many hours to render. vray is so good because it allows you to make compromises in the areas that you tell it to to bring down render times. but how long will it be before computers are powerful enough to get maxwell renders in a few hours? then we will all be using maxwell for archicad, and by then maybe archicad will be a great modeller! oh, if only...
