Blender doesn't work with SpaceNavigator (Ubuntu 7.10 64bit)

Post by lopez » Mon Jun 02, 2008 12:41 pm

Hi,

I am happy (?) user of the Space Navigator. I've chosen it because of blender but unfortunately I have some small problems making it working with this particular application. But let's go from the begining. My system is Ubuntu 7.10 x86_64 (kernel 2.6.22-14-generic). The blender version is 2.46 which is supposed to work with NDoF devices via plugin. I've installed and run proper drivers for 64bit platform and Blue Light on SN switched ON, nice. XCube test application works fine and detects device without any problems. I was able to move the cube. XValues test application works as well. Then I've downloaded 64 bit version of plugin for blender (from blenderbuilds site because there is no such plugin available on your site, hmmm... why? ;>) and put it to manualy created directory 'plugins' inside my ~/.blender directory. So far, so good. When I start blender I have NDoF specific icons available but NO interaction between SN and blender. It seems no events go to blender when I use device. I was trying to use also sapcenav open source drivers. The light on SN was ON, spnavcfg was recognizing the driver but blender wasn't working. I was trying to modify xorg.conf file adding InputDevice section - no success. I'm using Wacom tablet and I thought it can generate problems. I removed it from system but - no success. The device itself works fine with blender but on Windows XP 32bit. But I'm not Window's user. I'm really confused and don't know what's going on. May be I do some stupid mistake? So, I decided to ask you for help.

BTW, when I start blender from terminal it seems the driver is also properly recognized:

Code: Select all

lopez@blaszak:~$ blender
Compiled with Python version 2.5.1.
Checking for installed Python... got it!
X Display: :0.0

When I start xcube app I have:

lopez@blaszak:~$ ~/Downloads/3dxware-linux-v1-3-0.x86_64/xcube 
3DxWare: xdrvlib.c 
3DxWare MotionEvent = 487

you mentioned you created a "plugins" directory inside ~/.blender : you shouldn't need to create a plugins directory, and in any case that's not where the plugins directory should be.

When you install blender 2.46 the plugins directory is already created. Find where your blender executable resides and in the same directory you should also find a plugins folder (containing texture and sequence plugins). It's in that folder that you should put our plugin.

After this, verify our driver is running. Don't run other drivers like spacenavd or others. Click Restore Defaults just to be sure, and set the Buttons to "Button 1" and "Button 2".

Hope this helps.

Hi,

Thanks for reply,

Yes, in fact I have in my system a directory /usr/lib/blender/plugins where texture and sequence plugins are stored. But moving that plugin file from ~/.blender/plugins (that's blender's hidden directory directly in my home dir) into this directory didn't help. As I mentioned before the plugin seems to be loaded by blender during startup when it is in ~/.blender/plugins. I have that information when I run in from terminal level and NDoF specific buttons appear in blender. When I move plugin to /usr/lib/blender/plugins there are no icons and no information during startup.

Yes, your driver IS working. XCube application cooperates with SN.

But I solved that problem in different way. As I wrote to you I was using a plugin downloaded from blenderbuilds site. That was a standalone plugin dedicated for 64 bit platform (3DxBlender-linux-amd64). In meantime I took a plugin provided together with older version of blender 'blender-ndof-2008-03-15-linux-glibc27-py25-x86_64' also taken from blenderbuilds. I put that plugin to ~/.blender/plugins directory and surprise, it worked. SN is recognized and supported. And it doesn't work if I move plugin to /usr/lib/blender/plugins, btw. There is slightly difference between this plugin and the one I used before. The working one is of size 10830 bytes, the second one - 11076 bytes. So, it seems that all of those problems was because of not valid plugin. And as long as you not provide a valid and working plugin for 64 bit linux systems nobody will be sure that he has a proper one, I'm afraid.

Thanks,

Where can I find the blender-ndof-2008-03-15-linux-glibc27-py25-x86_64 plugin
Using this now http://mirror.blenderbuilds.com/plugins ... -amd64.zip
Icons working in blender, xcube works, but nothing happens in blender :cry:

Get this message when I start blender 2.46, same as lopez

I am running Suse 10.2 on a DuoCore system. The SN did not work till I loaded the plugin in the reply from CasperN. Thanks.
