Been struggling with this one for more than a week now, as I can't work on it more than about ten minutes at a time, due to my poor old laptop constantly crashing Daz. I have 4GB of RAM, but am running at full CPU capacity with only Daz and Garibaldi open, and 100% memory usage.....have to continuously accept and save scenes with each adjustment, but until I can afford an upgrade, this is how I have to operate.....anyway, have yet to work on the second horse, but here it it so far......
4GB should be more than fine. Email me the scene and I'll have a look into if you still feel that a unusual amount of memory is being used.
A few tips to save memory are:
* Only active character surfaces you will be creating hair on.
* Reduce the Garibaldi hair preview percentage.
* Don't use hair width preview.
* Increase the Garibaldi style interpolation segment length.
* Reduce the Garibaldi Undo/Redo limit.
....my laptop freezes trying to use uber environment, so if anyone has any suggestions of lighting that resembles uber environment, but won't kill my PC, please let me know....much appreciated, and beautiful renders from everyone so far!
The uber lighting tools in Daz will cause 3Delight to do various on the fly caching operations to speedup rendering the more advanced lighting effects. Although these caching operations make things quicker than simple ray-tracing but they may need quite a lot of memory.
If you want to render lots of hair with not much memory then use deep shadows with spot lights. Deep shadows were designed for rendering things like hair.
If you want to reduce the memory usage and increase speed of the UberEnviorment the try reducing the 'Maximum Trace Distance' (maxDist), reducing the 'Occlusion samples' (samples), increasing the 'Shading Rate' and increasing the 'Max Error'.
The UberEnviorment almost certainly uses the 3Delight 'occlusion' and 'indirectdiffuse' shader functionality, the technical docs for these are here: http://www.3delight.com/en/uploads/docs/3delight/3delight_35.html#SEC134
