SERGYI

Hello! I tried to reproduce the problem, but no luck – in Linux Ubuntu 9.04 and CentOS 5.5 the dialog worked without crash. But during testing another issue had been fixed. If external editor had point in its name then 3D-Coat couldn’t run it. Now it can. I see that both of you are using Linux Ubuntu 10.04. Maybe it is something specific to this version of Linux. So I’ll try to install it.

Hello, there! As it turned out, NVIDIA CUDA Toolkit on the system should be exactly of version 2.3 (June 2009) to work correctly with 3D-Coat. Maybe in the next releases of 3D-Coat CUDA libraries will be included within 3D-Coat package (the same linking as with Intel TBB libraries within “Libs” folder of 3D-Coat). But it is suspicious, why NVIDIA offers different CUDA Toolkit packages for different Linux distributes? Maybe there are different libraries for different Linux distributes? If so, the most optimal solution would be compilation with NVIDIA CUDA Toolkit 3.0, which will be done in the next update.

Hello, Linux users! Thanks to Flytronik, several days ago we fixed old and critical bug – on some Linux systems, 3D-Coat had distorted manipulators, distorted models after any import from “obj” files, and crashed from time to time. As it turned out, the problem was because of standard “C” library function “atof” (converts ASCII strings to float values). When system language is other than English, “atof” uses comma instead of point as decimal separator. In every place of 3D-Coat, where “atof” function has been used, under non English Linux systems we get incorrect results when converting strings to floats. The latest version of 3D-Coat on the FTP server should work correctly regardless of system language. So everyone, who has such critical problems on non English Linux systems, please download the latest version of 3D-Coat!

Hello there! 3D-coat crashes and freezes the computer because of the NVIDIA driver’s version. Please, install any NVIDIA driver except 195.36.15 and 195.36.24. Here is the discussion of this known problem: http://www.3d-coat.com/forum/index.php?showtopic=5576

Hello! We received answer about two weeks ago by email from NVIDIA engineer, that they found the problem and fixed it in the upcoming driver update. Until next release, please use any driver except 195.36.15 and 195.36.24.

Hi digman! NVIDIA driver since 195.36.15 contains critical bug. I created post on NVIDIA forums but didn’t get any reply. http://developer.nvidia.com/forums/index.php?showtopic=4540 So please install any driver before 195.36.15 for now.

Hello. I encountered with that problem several weeks ago under Fedora 12 (64 bit) with NVIDIA drivers 195.36.15. After investigation it was clear, that was bug in the driver version 195.36.15. I submitted appropriate post on NVIDIA forums a week ago. http://developer.nvidia.com/forums/index.php?showtopic=4540

Hello Flytronik! Thanks for your participation. I was messing around with openSUSE 11.2 (64 bit) and 3d-coat for several days. As you may know, the NVIDIA driver isn’t integrated into openSUSE because of license. There are two ways to get NVIDIA driver: through repository or with manual compile. The last option strictly requires the same header files and libraries which were used during kernel compilation (http://en.opensuse.org/NVIDIA/The_hard_way). So within “YaST->Software>Software Repositories->Add” I added repository “http://download.nvidia.com/opensuse/11.2/” . Then launched “YaST->Software->Software Management”. The driver “x11-video-nvidiaG02” for my NVIDIA GeForce 8800 was automatically selected, as well as new kernel file. After installing no issues with 3d-coat were discovered (see attached screenshots for microvertex mode, per pixel painting, reference mesh option, and voxel sculpting with manipulators). Such issues with 3d-coat under Linux have been reported several times on this forum, but after installing Linux version specified by the user we were unable to reproduce the glitches. Therefore I think that such cases are related to improper video driver operation (maybe with such trivial things like vertex attributes input from vertex buffer within vertex shader). Please try to use specified repository to get driver.

Helmut S. Thanks for your participation. Yes, I was thinking about static linking. But according to the “makefile” the only dynamic libraries are these two: 1. OpenGL which is dependent on graphics card driver vendor, version, and should be dynamic; 2. GTK+, which during runtime links to a lot of other system libraries. Maybe among them are some, which lead to such graphics issues. But most of them are system specific. And static linking against them is the same, as static linking under Windows with “GDI32.DLL”, “USER32.DLL”, “SHELL32.DLL” etc.

Hello Helmut S.! My favorite is Linux Ubuntu 9.04 (64 bits). Standard drivers 180.44 are just what 3D-Coat wants :-D

Hi Helmut S.! Thanks for your feedback. Frankly speaking we are aware of that problem. Several users complained to those issues. You know, we observed what they have in common – Kubuntu and GeForce 9 / 2xx GPUs. We tried to install Kubuntu. With GeForce 8 there were no problems. In the same time there are a lot of users on Ubuntu with GeForce 9 / 2xx and they have no problems. Can you try to install Ubuntu instead of Kubuntu? Of course we are very interested to workarounding that problem under Kubuntu with GeForce 9 / 2xx GPUs, but couldn’t reproduce such issues on our workstations. Those issues are definitely somehow connected with graphics card drivers.

X-13 Thanks for your feedback. Have you tried the “3d-coat-64-TEST” executable? Does it contain the same manipulator / mesh distortions like in regular “3d-coat-64”?

puddie RC4 has been updated just now. It contains additional executable “3d-coat-64-TEST”. Please report do you still have manipulators / mesh distortions with that executable?

Please attach here “Log.txt” file from the 3d-coat root folder. And screenshot would be nice too.

cuffins Morpheus haikalle RC3 has been updated again. There should be no Increase Resolution crash. Please test it !

haikalle RC3 has been updated now. It contains fix for small interface on start up (that was illustrated on your screenshot). cuffins Morpheus haikalle Regarding to “Increase Resolution” crash… Is this “feature” only of 64 – bit version of 3d-coat, or 32-bit version also has it?

RC3 has been updated now. vil There was some mess with file / folder permissions set: folder got permissions for file, which is inacceptable for Linux. That bug has been fixed. Thanks. cuffins To reveal those bugs I installed today Ubuntu 9.04 64-bit. Per pixel painting really crashes, but only if texture size is 8192 x 8192. In Windows there is the same behavior, and it is really because of “out of memory” case. Please try to set texture size to 4096 x 4096 and see the behavior. About increase resolution… Tried dozens of times but with no luck to see the crash… Morpheus Which of?

Thanks for your report! Please download RC3 which has been updated today. If you still will not be able to use eraser and pressure features of the tablet, please post here and attach “Log.txt” file from the 3d-coat root folder. Maybe it will be possible to figure out the problem.

haikalle RC3 has been updated just now. Please try it. If you still have the problem, please report here and attach “Log.txt” file from the 3d-coat root folder. And everyone! 3d-coat should support tablet in Ubuntu 9.04 out of the box. If it doesn’t on your computer, or your tablet is not “Wacom”, please report here and attach “Log.txt” file.

jim Thanks to your hint about title bar flickering the problem has been localized and solved. Also that bug could damage 3d-coat files. So please delete version and download updated just a few minutes ago RC3 archive.

haikalle geothefaust RC3 has been updated again recently. This time it contains fix that enables 3d-coat to use Wacom tablet under Linux Ubuntu 9.04 out of the box, i.e. w/o “xorg.conf” file modification. kay_Eva Don’t be afraid of Linux. Latest version of Linux Ubuntu is absolutely amazing. Drivers are installed automatically through Internet. Updates are also automatic. This is OS for which productivity, stability, maintenance-free ability, and efficiency in accessing and using user’s applications are in the first place. Frankly speaking, tuned Windows XP also has those abilities, but in Linux Ubuntu you get all those out of the box.

haikalle geothefaust About problems with “Right Control”, “Right Alt” and “Numerical Enter” under Ubuntu 9.04 you were right… Moreover, for some weird circumstances hardware codes in Ubuntu 8.04 and 9.04 are different for “Insert”, “Home”, “Page Up”, “Delete”, “End”, “Page Down”, “Left”, “Right”, “Up”, “Down”, and “Numerical Divide” keys. Uploaded RC3 version contains appropriate fix. Thank you!

Thank you all for your positive feedback on the game – it is very important step for the engine cross – platform evolution. Roger_K The game itself is real-time for sure - 50 – 60 FPS on Xbox 360. The Net animation is calculated based on 4 animations: stand, jump, fall, run. Because of animations weighted blending transitions are smooth. Now the engine has been completely ported to Linux. Every function works as expected. We’re going to the last step: compiling the whole project – the engine + platform independent 3d-coat files. P.S. Do you know that installing Wacom tablet under Linux is not a simple task!? To enable eraser and pressure support you should perform several user unfriendly things.

Hi all! I’m porting engine on which 3d-coat is based to Linux. Sorry for delay , but I was very busy with my another project – platformer game for Xbox 360 and PS3 ( ). It is really difficult to work simultaneously on two different projects. But for now I’m totally focused on Linux port, so beta testing will begin shortly (I hope ). Most probably for beta testing there will be only 64-bit version compiled on Linux Ubuntu 8.04.
