...if anyone has any experience with or knowledge about importing a Revit model into SU? Could there be a Revit-SU marriage?

My objective is to render out of SU (Podium and/or a NPR). I am aware of accurender being 'integrated' with Revit, but thats where my knowledge about accurender ends. Besides there is a deadline looming large and not enough time to learn a new sw/engine.
So was wondering if exporting the model out of Revit, bringing in SU, massaging in SU and running a render is an option?

Thanks

I am not expert on Autodesk products but there must be .3ds export from Revit or failing that .dwg and or .dxf. With the later ones you will loose  textures though.

Rendering has always been integrated into Revit via the Accurender engine. I believe this is still the case. Given that Accurender is a competitor to AuroDesk Viz, there has been speculation for a long time that Viz would become the integrated render engine.

Also, the AR engine used to be version 3, whereas version 4 is has been recently released. I'm reasonably sure that AR4 isn't the engine in Revit, and that it still uses V3.

I participated in the AR3 beta test programme for a long time, and used it for a quite a while after it was released. I like it as a renderer, and the latest version seems quite powerful. It is very easy to use, but not in the same league as Podium

It should have 3d dwg export facilities.

When you say it's not in the same leauge as Podium, do you mean it is harder to use/setup, or it dosn't produce renders as nice as Podium??

Quality of output is comparable, better in many respects. Not nearly as easy to use though, that is where Podium is the undisputed king.

http://www.accurender.com/

Podium's quality will defintely improve though, and I would say it should be quite a bit faster.

[Edit: I just had a more detailed look at the V4 gallery and actually the images in the V3 one were better . There are only a couple of images there that really show what can be achieved. Artificial lighting effects are more subtle, it has bump mapping, ripples (for water), blurry reflections and a procedural texture editor. It has radiosity
which is inferior to Podium's photon mapping & final gathering though.]

I  have seen the image gallery of Accurender.I think podium can produce more realistic images compared to accurender and definitely easier to use....

i dont know if this is the proper thread to use since this thread is about revit and su. sorry iruser. but since the topic tackles the subject of comparing rendering engines may i know some of your thoughts on comparing podium with other rendering engines (vray for su or others, atlantis, and others.) like bigstick, solo and biebel and many others, i know had tried and have tons of experience on these different engines. can you share some of your evaluations so far.

I hope my comments regarding Accurender haven't been misunderstood. I don't think it is a better render engine, just that some of its features are currently superior to Podium's. I also think that certain scenes will look better rendered in Accurender, particularly ones with blurred reflections and/or bump mapping.

If you look at some of the renders which have artificial lighting (default sun still has sharp shadows - not good for V4!) the light distribution is better. It also has a library of landscape and light components you can just drop in. Accurender's lighting library is really nice, you select the fitting, lamp type and light strength and everything is done for you. You can also group fittings and adjust lighting parameters for all fittings of the group in one go.

Podium's GI implemention is far superior however. I am confident that it will be a far superior render engine in terms of quality (it already is in terms of usability apart from the lighting library) and definitely before the end of the year. I just don't think this is the case for all types of scene at the moment.

I think it is always useful to discuss other render engines. Podium does not exist in a vacuum and has lots of competitors. We can learn a lot from some of them, from their bad points as well as their good ones.

But whats great about Podium is that you have complete control over the lighting system depending on your creativity  and technique .For me this  is the ultimate strength  of podium.In terms of textures and materials.There are a lot of materials available on sketchup including its components.Materials and and other 3d objects can be easily made in sketchup compared to other softwares like autocad ( I hate doing 3d in CAD...).The combination of Podium and Sketchup is really nice because it removes the technicalities while enhancing efficiency.After all,"time is gold".In a year or so after podium resolves its problem on rendering speed in interiors. I think it will be hard for other softwares to compete with it.(There are a lot of really impressive podium renders on this site......).

Trust me, you really *don't* have complete control over lighting!
Omni size configurability is limited and falloff can't be controlled at all.
LEM brightness isn't good enough and they render too slowly in any event.

I agree with you in relation to that in a year I think it will be difficult for any renderer to compete with Podium. I have been testing some stuff that may turn out to be the next generation technology for Podium and it is really fabulous! We won't get Maxwell quality, but quite close and definitely comparable to VRay quality.

It's far too early to get excited yet however

i think the real strenth of podium comparing with other engine is it is really easy to use. even beginners will have photo realistic images in just one click. second setup is so easy too. the ui is not complicated and it really suit with the beginners, that is why it suit with sketchup. the quality i should say its coming closer with maxwell and vray. once bump is there, photo realisim will be achievable.

i agree with bigstick and zem that perhaps more control on light should be dealt on the next releases. we all know that once these tweakings are there, men i could not imagine how podium can compete with others. as for further improvement of speed with next release....wow. really exciting. good luck tbd. but always prioritize your family.

oh another thing i think this forum has really friendly and helpful community that you will find pleasure in learning your ways in podium. i wish i can join some other guys there in london. but let me go to my emerald cruise first in the bay of Halong.
