Some time ago I posted that M3 had a weird problem with the left bicep.  I had installed all the service packs, but the problem was still there.

Someone mentioned a temporary file that poser creates.  Remove that temp file, they said, and then Poser would create a new one with the fixed M3.

Does anyone know that that temp file is?

the left bicep problem is that you need to reinstall new versions of both the morphs and M3, go to your DAZ, account history, and reset both M3 and the morphs, and download them. the problem was a very early issue, which as I recall was fixed less than a week after he was released, and if the figure in your poser runtime that you are loading isn't Michael 3 SR1 you are using the original figure which was where the problem was.

oh the temp file was an .rsr file that gets created in the geometries folder but you wouldn't get that unless you are still using Poser 4

I reset and reloaded back when I was first encountering the problem.   That didn't solve the problem.  The figure I use is Michael 3 SR2, and it still has the bicep problem.

You need to redownload the morphs then too

yep if you are still getting the problem than you need to redownload the body morphs. also if you are using more than one poser runtime, make sure that you only have one Libraries/!DAZ/Michael 3 folder

I had also re-downloaded and installed the morphs. 

There are two Michael3 folders...one is in the default runtime and one is external michael3 runtime I use.

Both have the problem.  Just noticed the left calf is unaffected by morphs such as calf bulge.

I've tried deleting everything, re-downloading and re-installing.  The problem is still there on the left arm, as well as the left leg.

you have deleted the files from both runtimes? including the !DAZ/Michael 3 folder? I would try an experiment, since you have redownloaded and reinstalled, which runtime did you reinstall into? hopefully into your default. now try removing every other runtime from your library list other than your default, and downloads(Becouse you cant remove the downloads folder). now close and reopen poser and try loading and injecting M3. is there still a problem? if not than I would say you still have a runtime containing an old version of the morph deltas somewhere.

I got completely fed up of trying to fix this about a year ago: like flibbits I've downloaded the latest versions of M3 and his morphs, deleted the old ones entirely, and I still get the problem described.

And since my most recent attempt at this was on a completely new system, I am completely baffled as to why this problem persists.

These days I use D3 as he's a better mesh, so I'm not that bothered, but it would be nice to know what the hell the secret is for getting M3 working properly.

don't know what to tell you, as I said this was a technical problem that the M3 files had on innitial release that was fixed extremely soon afterwards, so I have no idea why you would be having problems if you are sure you are using new versions of the base figure and bodymorphs becouse that problem hasnt existed since.

I never installed M3 until last year, which should have been well after these problems.

However I think I fixed it.  I overwrote the M3 geometries in the default runtime with the M3 geometries from the new download.  Not sure why reinstalling it didn't fix it in the first place, but maybe I was somehow not overwriting that old file even when I thought I deleted everything.

Bottom line is check the

runtime:geometries folder (default runtime.)  Look at the DazPeople folder, that's where it seems to be loading the geometry regardless of whether you install M3 in a different runtime.
