Scenes that make use of displacement mapping can quickly exceed what fits in current higher end graphics cards. Displacement mapping is a technique often used in archvis.
In Blender it is very easy to see how many polygons a subdivided model uses and how many levels of subdivision are needed sometimes to show finely detailed structures without tessellation artifacts.

Just start tinkering with sculpting tools and see your free memory disappearing rapidly due to the high number of polygons needed for the fine detail that you are trying to carve!

Tom, I guess that answers your question ?

Modern architecture sometimes use large flat surfaces with textures and few polygons, but sometime more detailed and modelled meshes are requires if you want to model gothic churches for example.

When doing organic modelling or modelling complex scenes with both characters and highly detailed subsurf models, the polygon count quickly increases.

In the scene I am working on (Rough render made with Octane - I don't remember the poly count : I am not on my workstation right now), there is only a detailed car in a desert, and the memory required amount is already 750 MB on my 860 MB available on my GTX260 ! I have no more room for my character which is detailed an subsurfaced ! And the set is only a desert made of a low poly deformed plane with a texture !

So you can imagine the memory requirement for a scene with several characters and some trees for example !

It was a rhetorical question as it's also because of high resolution rendering + shitloads of vegetation. It's silly to say that 'most scenes' can be fit within the 1-1.5Gb memory of a video card. But yes, displacement can make the amount of polys in your scene explode very easily.

Will the program allow GPU rendering across multiple computers? Say for example, on a render farm.

Indigo has great networking features, and is already supported by the Ranch Render Farm. It will simply leverage available GPU power (if any) on each node :)

At this stage in devolpement of the GPU beta, it only works with Nvidia CUDA cards.
OpenCl support (for ATI etc. Cards) is planned at some point...

If you try it out on a Nvidia System, you need the latest (beta?!) Drivers, since CUDA also develops
with each driver release, and older drivers that maybe use CUDA aren't supported...
I have nvidia gtx 295 1800mb..I think that this card should be fine...is this?
sorry for my poor language

Hi Filippo! Your video card should be good for GPU rendering.
Make sure you have the latest CUDA drivers installed for Indigo to work properly.

Yes, that card works Filippo, though keep in mind you can only utilize one of it's GPUs at a time.

Sorry Godzilla: you seem to have the thing cleare than me.
Could you spend a couple minutes to explain us what do you mean? How does Indigo andle the video card's power? I have a GTX480: what is its actual power used?
Thank you a lot!

Hey Pibuz,

the gtx 295 is a dual Chip Graphic Card. Something like two cards on 1 board.
Indigos latest Betas only support 1 GPU per system, so this beast would only be used with 50% (1 GPU crunches rays, the other sleeps)
