When opening a large model (about 29M faces), 3D Coat 2024 (and 4.9 as well) crashes when application memory usage reaches about 4 Gig. Just before the crash, it displays a rather ridiculous message about increasing VM size in the OS settings (which isn't even possible). This is a 64 bit app, on a 64 bit OS, on a machine with 160 GB of RAM and about 8 TB of free disk space. Full crash reports and a sample file can be provided. Let me know what you need to help debug this issue in your code. --------------------------------------- Process: 3DCoat [13840] Path: /Applications/3DCoat-2024.31/3DCoat.app/Contents/MacOS/3DCoat Identifier: com.Pilgway.-DCoat Version: 2024.31 (1) Code Type: X86-64 (Native) Parent Process: launchd [1] User ID: 501 Date/Time: 2025-06-13 15:12:23.3744 -0700 OS Version: macOS 14.6.1 (23G93) Report Version: 12 Bridge OS Version: 8.6 (21P6074) Anonymous UUID: 096D5B68-B94E-63F0-17DD-11136D1F6B88 Time Awake Since Boot: 2300000 seconds System Integrity Protection: enabled Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000 Exception Codes: 0x0000000000000001, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 Terminating Process: exc handler [13840] VM Region Info: 0 is not in any region.

Hello I bought an alpha pack from artstation and I usually just add the .psd to 3Dcoat with the "Add Existing Folder" button on the brushes window but this time I get an instant crash when loading the psd folder, and even if I leave 1 psd inside the folder it still crashes, attached the psd and the error window What would I need to do to load all that alpha pack succesfully? Thank you 155_Mech_Alphas Set_02_001.PSD

3DC crashing when exporting gltf files. I updated to the newest version and its still happening, i have done everything as per the video Carlosan posted about exporting gltf files for SL and its worked on other models but this one it says resave as this file is corrupted as it gets to a certain uv set, then i save to a new file and rinse repeat. Can anyone suggest something to me or know why this might be happening? Thanks

I just installed 3dcoat textura on my Linux system. Trying to import a mesh closes the system or opening a file or doing almost anything

After a few seconds, 3D Coat crashes immediately with no pop-ups. STEPS TO REPRODUCE: Download 3D Coat 2023.17 for Linux Unpack 3D Coat download Double click on 3D Coat executable file Load object for per-pixel painting Open or import an image file that isn't included within the 3D Coat build (i.e. textures and previews) Navigate to the directory of the image file to open Wait a few seconds Log copy.txt

Hi. I'm brand new to 3D Coat and want to learn it so I can teach my students. I've downloaded the free trial so I can use it at home, but when I try to launch it the program crashed before it even loads up. I've tried launching both the OpenGL and DirectX versions but the same thing happens to both. I'll attach a screenshot of what happens when it crashed to this post. I hope someone out there can help me with this as I don't have any idea of why this might be happening. I'm running Windows 10. Thanks.

I've reported this a bunch already. My last resort is posting here. Can anyone help. System; i5 6600K, GTX 1070, 16GB DDR4 This is what keep showing up. Nvidia drivers are up to date. Not sure what the hell is going on.

So since 4.8 when I go to bake from Retopo room, there's like a 50/50 chance my whole Pc will just shut off. I make sure -There's no NGons -I'm in Global space - I fill voids I was even restarting 3d Coat before the bake everytime which helped but now it seems to be crashing everytime. Not sure what the problem is, would appreciate some help.

Hey everyone. I've been running into this strange problem where my model keeps disappearing when I hover it. The model isn't actually gone, it's just a visual glitch and I can usually get it back by hitting one of the preset camera positions. This time it really bugged out and I was able to screen cap a video of it. Has anyone else run into this problem? My models are pretty low res and my machine is brand new with up to date specs so I don't think it's hardware. Not sure though. Let me know if anyone has any suggestions. Thank you!

Ive used Z brush and so I know modellers crash , but the question is always why. Using curves in 3dcoat looks easy in tutorials but my system , which is quite big wont go there. Is there a setting in prefs or something that keeps down file size , my system is overloading before Ive even built anything . Ive got windows 7.... 6 gbs of ram.... 6 core phenom and use DX not GL as GL shut it down. Any info welcome Im still on trial and so far can only use paint .

Last night I downloaded the trial for 3D-Coat, which would mean I have the latest version of 3D-Coat, but after I installed together with DirectX, 3D-Coat is unusable with the crashes. I launch the program, and it loads fine, everything appears normal. On the main splash screen that opens on the program's launch, if I click any of the options there (Voxel Scultping, Hard Surface Sculpting etc etc etc) the program crashes. For example, if I click on Voxel Sculpting, I go to the next splash page where it has the various options - the primitives and the bust - yet if I click any of these, the program crashes. If I bypass the splash screen by clicking the X in the corner, I can then be in the program, but as soon as I click on anything, the program again crashes. There are no error messages beyond the standard Windows "The program has stopped responding" This was last night, and after I booted up today the issues persisted. I launched the program 4 times to the same result. However, and this is the kicker, as I have been typing this message, I have managed to not only load a primitive but also the bust and I have been able to roughly sculpt on it just to determine the program is working. Is this a quirk of 3D-Coat, with the clap-on clap-off crashes, or could it be a compatibility issue? Admittedly the problems with 3D-Coat crashing for no apparent reason and giving me no error messages is making me uneasy about getting Zbrush next month. (There aren't any trials for that, to make sure it will work on my system.) My machine is Windows 7 64-bit, 32GB RAM, Intel Core i&-4960X 3.60GHz processor and NVIDIA GeForce GTX 690 videocard.
