Simplify3D User Forum

Since 2 days Simplify3d keeps crashing when i select a new material profile.

It ask to save the current one and after that it crashes.

Tested with 3.0.0, 3.0.1 and 3.0.2

Still crashes, this is a huge problem and not workable anymore!

Some more info:
- Windows 8.1
- Happens also when i update a profile
- It happens only with certain (newer) profiles (not all profiles)
- When i export them as FFF they are 0KB

Any thoughts?????

Works fine for me. It probably means you have a typo or something corrupt in your profile. I would delete that bad profile and start over.

I've been seeing similar problems lately. Here's what I (think) I know now.

BTW, I'm running S3D on a Windows 7 Pro, 64-bit PC.

If I look at all of my exported (saved to local disk) .fff files, I find that if they aren't zero-length, they have one of three lengths:
-- 8K - 9K (these turn out to have been created in S3D 3.0).
-- 21K (these turn out to have been created in S3D 3.0.1).
-- 22K (these turn out to have been created in S3D 3.0.2).

Those lengths also apply to .fff files that I'd derived from .fff files of those lengths, also.

Only the 22K-length files represent profiles that are stable when editing their contents (they don't crash S3D).

When I make a copy of a 22K-length profile by using "Save As New" in the profile-editing window, I can then change the copy all I want with no crashes.

BUT, I've found that if I've run a "crasher" .fff file with S3D, to get things back to normal I have to shut down S3D, bring it back up, immediately load a "good" profile, then I usually have to shut down S3D again. When I restart it, it automatically restarts with a "good" profile as the current one, and it's in a good state.

After that I can copy the profile to a new name using "Save As New" as mentioned above, and it always seems to be a clean file that I can edit, save, export, etc. And if I do export it, it'll be a proper 22K-length file.

So it appears to me that ever using any profiles created with earlier versions of S3D, or copying and modifying them, generates .fff files that will -- sooner or later -- crash S3D. But following the process above, in my limited testing (I just figured this all out this evening) SEEMS so far to give stable operation again.

I'd be interested to see if this is your experience, also, if you decide to try it.

UPDATE: that's not the whole solution, I'm finding out.

When I "Save As New" a known-good profile under a new name, and then try to modify that and do an "Update Profile", the program crashes.

Also, if I Export a known-good profile (and see that it's a good-looking 22K file), change its name in Windows, and then Import it, S3D says it imported it successfully. But if I try to select it from the drop-down list, the program crashes.

EDIT: Even if I select the Default profile, save it as a new name, and try to modify any settings, the program crashes.

So that all tells me that I can't save ANY new profiles now! I assume that means the Windows Registry for the program is trashed, or something similar.

Sigh. Back to the drawing board. Probably time to delete and re-install the program, to see if that helps.

Do a Help > Reset All Settings. That will restore program to all stock settings and delete any bad profiles.

Woohoo! That seems to have fixed it!

I'd exported all my profiles to a safe spot on my hard drive before doing that, which turned out to be a good idea, as doing that deleted ALL of my profiles. But importing them back in seems to be working fine, and now I can make changes and save them, etc. normally again.

Thanks!!

Little update: Indeed, Reset all settings solved this for me.

Thnx all!

Same with me. WIN10 64 Bit.

Has S3D commented on this?

Read above. It probably means you have a corrupt profile that is doing something the software doesn't like. So either find and remove the bad profile or just do a Help > Reset All Settings to clean them out.
