What does clearing the cache do exactly?

Sorry about spamming the forums with multiple issues but have a cache question - took me tons of attempts and 3 days to render my scene but I’m now getting RC crashes (not OS like before) whenever I try to texture.

I just had a massive hard drive failure - though no files changed for this project EXCEPT for the RC installation drive. When I analyze the dump file from RC in Visual Basic I get

Dump Summary

Dump File: RealityCaptureCrash_6278_81716-668_1_0_2_2393_Steam RC.dmp : C:\Users\xxxxxxx\AppData\Local\Temp\RealityCaptureCrash_6278_81716-668_1_0_2_2393_Steam RC.dmp

which makes me think that pre HD crash it has references to the RC installation directory somewhere. So I have to blow away my cache…

I have a 986M tri colorized model, have singled out a 700M component to work on, simplified it to 6M.

When I blow away the cache, what processes that I have left in my workflow (component out a part of the big model, simplify, unwrap, texture, export, import reconstructed, unwrap, texture, export, etc. etc.) should I expect to spike now that the cache is gone?

This is important as this project is meant to measure time (hours spent in post and hours spent rendering) - I want my notes to reflect that I spent extra rendering time if one of those processes above spikes due to the cache removal.

Thanks all yet again…

EDIT: Ughhh, clearing the cache didn’t remove the problem. Oh well, I would have been thinking about it until resolved anyway… Any ideas? Can’t texture my model at the moment.

Sorry to bump this, but I need some help. I have all my computer problems squared away but RC is crashing with a dump file every time I try and texture a model for export. I’ve tried importing new models, clearing the cache, uninstalling and re-installing RC a few dozen times.

Any suggestions? Dump file’s header is in the original post. Thanks.

Hi Castlenock
can you post details on the UNWRAP settings and texturing options used?

Wishgranter,

Thanks for looking into it! Attached is a picture of what I like to default to - I have played with these options a bit in hopes to get past the crash but to no avail.

Also tried fixed texture on a simplified cut-out of a 25k object (reduced from 3M), and that crashed as well.

Hi Castlenock
and the UNWRAP parameters ? click on the MODEL to display the UNWRAP info…

Ugh I’m an idiot. Here you go.

Any suggestions? I’m up against a deadline here and at the end of my rope - the first 7 days were due to computer issues, but this is squarely RC at this point. I’ve tried everything, what can I do to fix this?

I have an old save file of a good re-alignment, should I reconstruct on high (2 to 3 days) to continue? I don’t want to do that as I don’t have the time, but I have exhausted all other resources here.

Hi Castlenock
and when you use the FIXED TEXEL size and set the OPTIMAL TEXEL VALUE in the UNWRAP tool ( recalculate UVs ), do you get in the same issue ?
Please, let me know. If not, could you upload the whole dataset so that I can process it here for you ?

Wishgranter,

You’re the best! Yes, when I used fixed and set optimal to the best value, unwrapped and tried to texture I got the same error.

I’m still not-where-I-normally-am and make a physical move next week so am starting to prepare for that - getting the dataset up would be difficult, but not impossible (I’ll ask the local university I was on contract with to use their pipe, my upload pipe is laughable). I’ve started a high reconstruction with 2 GPUs (and a proper power supply) that bugged out after hour 20 and think it salvaged about 20% of that render… If I get another high-recon off of the initial alignment by tmrw morning CST I can try texturing from that, and if it doesn’t work I’ll chase you up for potentially looking at the data set. (That’s such a gracious gesture and I hope not to take you up on it).

Even though it’s an RC error and my image, RC, and other data sets weren’t on the drives, I’m sure my ‘SDD and HDD Backup Drive Apocalypse, 2017’ fiasco is at the root of the issue. Are there any suggestions on making sure RC is completely re-installed and that there is no residual references to the installation of the program anywhere in a Windows 10 OS? While the content was on a stable drive, RC’s installation drive was on one of the failed drives.

Wishgranter,

Thanks for all your help, including the PMs on the matter. I sent you a few PMs but to be honest the PM interface with this forum is so confusing I have no idea if they were sent or not (if I sent multiple, my apologies).

The High-recon redo didn’t work, some changes in the registry didn’t work, and a registry removal and re-install didn’t work on any of the save files for the project on hand. At this point, I’ve uninstalled, cleared the registry, reinstalled and started a new project from scratch to make my deadlines. If I can get the University to grant me access to their up-pipe I’ll load whatever source files you think relevant.

For anyone listening in, I think this is an outside issue that is more to do with my computer melting down mid-project than RC… But if this recon run doesn’t work than I have zero idea of what the next step would be to fix it.

Today’s world every people are using computers and mobile phones to access the internet for surfing, downloading, chatting, social media, etc. So, some files are generated in memory of computers or mobile phones which are called cache and cookies. Web-pages can only communicate and interpret with browsers. There are different types of browser likes Internet Explorer, Google Chrome, Firefox, Safari, etc. Each and every browser has own privacy policy and history. It is more crucial to think on browser’s cache and cookies when we talk about browser’s privacy and history. how to clear cache The cache file is a temporary and small file which consists of a copy of visited HTML webpage’s code and images when we surf on the internet. So, next time when you again visit the same website then your browser fetches some data from previously stored Cache file and render it to users rather than its website original location. Cache files are used to speed up web page process by fetching same data rather than re-downloading again. So, it saves users time and quicker system performance while surfing.
