I'm running out of memory on the farm on one of my comps. I don't remember running into this kind of thing with a comp of this size on nuke 6.3x and I'm wondering if I have missed something.
I've precomped all the branches that I can. I've also turned off all postage stamps. I've also tried turning down the cache memory usage to 10%, along with turning all memory settings to very low. Renders consistently run out of ram on the farm. The farm nodes have 16GB RAM. On my comp station, this comp eats 22GB of RAM, until I clear the buffers. It's a somewhat large comp. 781 nodes. 762 channels. About 75 read nodes (reads are CG passes) HD inputs are between 2MB/frame and 8MB/frame Rendering zip1 16 half EXR Environment: Windows 7 Nuke 7.0v6 same config on farm, except 16GB RAM Looking at my buffer report, I'm noticing a large amount of ChannleMerge nodes reporting memory usage of 300-400MB each. For example: ChannelMerge total usage: 339MB user data: cacheRegion 1920x1080 channels [... lots of channels listed here ...] usage 100% lossage 19 weight 0x0 another example: ShuffleCopy total usage: 247MB user data: cacheRegion 1928x1088 channels extraTex_vrayUserColor_restaurant01.g,nigel.body,props.dump,lloyd.body,linus,extraTex_vrayUserColor_set03.r,reflect.red,reflect.green,reflect.blue,refract.red,refract.green,refract.blue,specular.red,specular.green,specular.blue,GI.red,GI.green,GI.blue,SSS.r,SSS.g,SSS.b,diffuse.r,diffuse.g,diffuse.b,lighting.red,lighting.green,lighting.blue,extraTex_vrayUserColor_interiors.g,extraTex_vrayUserColor_restaurant02.r,extraTex_vrayUserColor_set01.g,extraTex_vrayUserColor_set01.b,extraTex_vrayUserColor_set02.r,extraTex_vrayUserColor_set02.g,extraTex_vrayUserColor_set03.g,gush.a,normWorld.r,normWorld.g,normWorld.b,gg.body,gg.hair,bldg.green,bldg.blue,bldg.alpha,lloyd.stripe usage 100% weight 0x0 Is this normal? Why are there lots of channels listed in the ChannelMerge node, when it should only be evaluating two input channels, and outputing one channel? Why is this comp so heavy? What am I missing here? Thanks for your help, Ryan
