Mudbox Displacement Map Blues

[james-thompson--2]

I'm trying to figure out why every time I attempt to make a displacement map of my new project I get Mudbox hanging and "Not Responding" ...

So I've finished my modeling,
http://www.highend3d.com/boards/index.php?showtopic=252963

BUT, I never worked out the UV mapping before I imported the base mesh. Was that a big mistake? It was my first real project where I've tried to generate a base mesh. If I haven't, am I screwed or will I just have to retopologize and sort out the UV map.

When I reduce my mesh down from level 7 (15,600,000 polygons) to level 0 the UV map looks like this;

Then I set up my map just like the video says...

Then I get all 8 CPUs hung up in huge page files at 89% usage for ever till I shut them down.

So what is the solution?

                             *    *    *    *   *

OK so I managed to extract a displacement map for another model that was UV mapped so that was ultimately the problem.

So now how do I go about fixing this mess with the Renaissance coin? How do I retopologize from this point? Do I somehow do it in Mudbox or do I take 15.6 million polygons into Maya and attempt it from there (Fat chance).

yes.

Uh-oh..

So what can I do now? Can I retopologize? Or am I without hope?

I havent tested, im stull working the mudbox workflow. But yes you can bring in teh ful mesh in maya and trasfer the attributes in here. But obviously if its HUGe your going to have some rpoblems unless your in 64 bit mayas
