ogs TextureCache

[Justin_DeSilva]

Beginning 02/08/2017 my machine began slowing down while using Inventor. More recently the application crashes, notifying me of limited memory. I noticed I was exceeding my hard disk space of 230GB but thought this was unusual because all my data is stored on another drive and only the OS and applications are on the local disk.

When reviewing local disk files I noticed a large portion of memory being reserved for Temporary Inventor files, over 66GB.

C:\Users\sesa207478\AppData\Local\Temp\ogs109245592\109245592_TextureCache

I don't recall this ever happening in the past and was curious why Inventor is saving large amounts of texturecache to the temp folder, and whether or not I can disable it from doing so.

Hi Justin_DeSilva,

I don't have any useful information, but did find this link: these links:

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Hi Justin,

We have seen such behaviors. 66GB seems a bit extreme to me. It could slow down all processes. Could you clean up the folder? In the meantime, I will work with the project team to understand the behavior better and see what we can do with these cache files.

Many thanks!

Hi Johnson,

Thanks for taking the time and analyzing the problem. I will also mention I notice a large amount of appearances being added to the Appearance drop down list, far more then I've seen previously. And, while editing features the TextureCache folder is overflowing with SimpleTexture***.dds files.

Justin,

Do you do a lot with imported step files,etc...?

Or how about a "custom" appearance library?

Or using the "adjust" tool to modify appearances?

Hi mcgyvr,

Do you do a lot with imported step files,etc...?

Yes, often with electrical components like USB ports, Modular Jacks and Terminal Blocks.

Or how about a "custom" appearance library?

Not a custom library but I've added 5 custom appearances to my Favorites.

Or using the "adjust" tool to modify appearances?

Previously yes but lately no. Only when modifying a default color to a Pantone RGB using the "Appearance Browser".

So I guess where I was going with that is that Inventor (for me anyway) still has issues/bugs if you aren't using the "out of the box" Autodesk/Inventor appearance/material libraries.. Which you seem to be doing I think BUT then you are importing step files and tweaking appearances on top of that so these kinds of things weren't as "solid/issue free" as just straight out of the box..

I've had numerous issues since 2013 when the big colors to appearance change happened.. Most have been resolved but a few still have not.. It used to be a big bug with another folder in Windows getting full of "protein run" image/textures not getting deleted after an Inventor session was closed,etc.. Seems like they may still have a few issues like that one or when "tweaking" the out of the box stuff..

Thanks mcgyvr,

Here's a screen capture of my custom appearances. They're rather basic so I wouldn't think they'd have a big impact on performance.

Hi Justin, 

Thanks for you posting this issue and letting engineer team know this case. 

Could you please help to provide more information about such issue for investigating from engineer team side? Thanks in advance.

1. What Inventor version are you using? 
2. Could you please capture one image for the folder structure of that folder, eg,  ogs109245592? Then capture one image for the files which reserving the disk?
3. I noticed that, there are ton of SimpleTexturexx.dds in temp folder, do you have any steps for how to generate these?

Any information are appreciated. Thanks. 

Thanks,

-Rui

Hi mcgyvr,

When selecting the material and appearance drop down menus I notice "Material" libraries listed under Appearances. It seems odd that Inventor points to these Material libraries when seeking only an appearance. Does this seem typical or odd to you?

[Justin_DeSilva]

Hi Rui,

What Inventor version are you using?

Autodesk Inventor 2015

Build: 223

Release: 2015 Service Pack 2 Update 6

Could you please capture one image for the folder structure of that folder, eg,  ogs109245592? Then capture one image for the files which reserving the disk?

See attached.

I noticed that, there are ton of SimpleTexturexx.dds in temp folder, do you have any steps for how to generate these?

The files are being created a variety of ways but most commonly are editing feature geometry and updating.

Hi Justin, 

Thanks for your information, but more information are demanded from your side. Thanks for your help. 

1. How did you import 3rd CAD file? And how about the configuration setting about import? If possible, could you please share some datasets with me?

2. Are you using Express mode and saving files? And, did Inventor exist immediately without any dialogs during that? 

You can send more information by mail, below is mail address. Any information are appreciated. Thanks.

Mail address, rui.wang@autodesk.com

Thanks,

Hi Rui,

1. How did you import 3rd CAD file?

When importing I drag and drop a .step file into Inventor, then save the file as a native .ipt file.

And how about the configuration setting about import?

When importing I don't see any configuration settings, the file will simply open. 

If possible, could you please share some datasets with me?

Will send to your email.

2. Are you using Express mode and saving files? And, did Inventor exist immediately without any dialogs during that?

I'm not familiar with Express mode but perhaps this is what's selected currently. I think so but I'm not certain.

Note: I should mention some .step files are edited using Rhinoceros 5 before importing. Let's use a USB PCB connector for an example. When downloading .step files from manufactures the original multi-body part is merged into a single solid body. To correct this I will..

1. Open the step file in Rhino

2. Explode the object or block instance

3. Separate the components parts like metal housing, plastic interior, pin contacts etc.

4. Create closed solid poly-surfaces from the geometry

5. Save as .3dm

6. Import .3dm into Inventor

Possible conflict: In the past I would save a .step file from Rhino for import but recently discovered Inventor will import the .3dm file. I stopped creating additional .step files to reduce file redundancy.

[Justin_DeSilva · Accepted solution]

Possible causes and solution:

After Inventor sessions end and machine is shut down the ogs TextureCache folder and cache dds files should be automatically deleted. If the folder and dds files are not being cleared there is a problem.

After deleting all unused appearances from individual part files, and assigning default or custom appearance colors (not textures) I'm identifying two possible causes for the dds error.

1. Custom appearance texture with image mapping (Approximately two months ago I created an appearance with a custom texture for mapping.)

2. Imported part appearance colors (Approximately two months ago I also began importing .3dm file parts directly from Rhino so as to avoid creating additional step files.)

I don't know which of these caused the disruption but I found both remaining in the unused appearance list. One of these will cause the system to hang, including after the appearance or part itself was removed from deriving or assembly.

Solution:

If a part, body or feature appearance was imported or user created including a texture, apply a default or custom appearance with no texture mapping and delete all unused appearances. After correcting individual parts and updating assemblies and master part file including the derived parts and assemblies the ogs TextureCache folder and cache dds files are being cleared.

I don't even use Inventor and noticed a tmp folder of 32Gb junk? Someone knows why?

[johnsonshiue]

Hi! The folder name seems to indicate it was created by the common graphics system shared by multiple Autodesk products. You mentioned that you don't use Inventor. Then what Autodesk products do you use frequently?

Many thanks!
