ram memory and mudbox

Dastan

OMG! I got Introducing Mudbox 2011 book and the first chapter lead us into creating an egg, an 1.5 million polygons egg, so you can use it later to create and export maps to use on a low poly version, but man! I am now in the painting process and it got 1GB of memory.. a simple egg! O.O

What about a character' s face, armor, or a very high complex object? I ask because I upgraded my computer's memory to 4GB and that is its limit but, if an egg is so memory consuming.. I' ll soon have to get a new computer..

Is there any solution to optimize memory consumption when sculpting high frequency detail in Mudbox?

And one more thing =[ I have memory left but I keep getting this message all the time when I start to create paint layers =[

Basically, it is telling you that your video card isn't powerful enough to handle that. Drop down a few subdivisions then paint on it. Mudbox is very memory hungry. Much more so than Zbrush. Also, the reason it is using up 1gb of memory is because you have 1.5 million polies. That is a ton for a simple egg.

Mudbox uses the memory on the video card to store textures while you work on them. You need to unload some of the textures while you work, use smaller texture sizes, or invest in a better graphics card with more onboard memory.

The system memory (your 4GB) is what is being used to store the geometry subdivision levels.

I though the system could normally share its memory, but in this case 1GB of video card memory is going to be a must for my next computer =o

i recommend a geforce 460 with 2gig of ram...

what does you mean with slow..?
during painting or sculpting..?
are you using large sculpting brushes at 1,5 mio..?

sli wont affect mud or maya...
only if you are using gpu renderer...

PolyHertz

Sli uses memory concurrently, so 2 cards with 512mb of vram each wont give you more then 512mb of usable mem.

Mudbox sometimes will run VERY slow on some meshes (to the point of being completly unusable), But i don't know if theirs a consensus on exactly what causes this. Does it run very slow for you on the default meshes that come with it at those division levels as well?

Also last I checked consumer gpus were not officially supported by Mud.

You should definitely be fine with those specs, maybe it is a driver issue.
