Large m3i-file won't load (Mandelbulb3Dv189x1)

[subarachnid]

I am trying to load a very large m3i-file (~2,2GB). My System has 8GB of RAM. Whenever I hit load, MB3D just shows loading: myfile.m3i in the info-panel, but nothing happens at all The program remains completely responsive, showing the previous formula. Has anyone else encoutered this issue? Is there any way to open this file?

Hello and welcome to the forums   

Your file may be too large to load.

MB3D is a 32 bit program and as such is limited to about 3GB of RAM (some can use 4 if Large Address Aware). You can have more RAM on a 64 bit system, but all 32 bit programs are still limited by their nature. They simply can't use any more. It's possible the overhead has been reached by the processes needed to load it.

It's best with such large files to save the parameters as m3p parameter files so you don't lose the information needed to re-create them later. Sometimes the m3i files are simply too big for the system.

Or it may be a corrupt save.

Has it ever loaded before and just stopped working, or is this the first time trying to open it after a save?

Wow, thank you for this fast response! Yes, it is the first time I tried to open the file after saving it.
It might be a corrupt save. I just noticed that the preview-image in the open-file-dialog looks scrambled

Sorry to hear that   

Best advice I have is to always save an m3p file with your m3i files - they only contain the information needed to generate the image and are usually only a few kb.  They don't waste much space and make a good back-up in case of these sorts of problems.

Can you recreate something close from memory?  If not, there may be people here who can extract the formulas from the corrupt m3i file - though how to transfer such a huge file may be problematic

Check in the History Folder, you probably have it in there somewhere I'd bet....load it from there then when saving M3i Files that are huge with downsized Images instead of Full size they are easier to load. I've saved large image M3i files that work later but the largest I ever saved was about 350meg and 7200x4050 that must be one huge image to take Gigs, no wonder MB3D had trouble saving and loading it.

Thanks for the save as m3p tip. I also had a problem with a large rendered image that gave me an out of memory message when I tried to reload the m3i, but I just lowered the saved image size and it was good to go. Thanks for the History Folder tip. Works great. I thought they were gone forever. I would load a large M3I with a corrupted image, it would ok the parameters and then nothing would happen. Using the History Folder m3p, I was good to go. Thank You!
