Then I saved the file in .max format and opened it with Deep Exploration. I saved the scene with Collada format and reopened it into Deep Exploration to see if the animation was saved. It was ok. I imported the .dae file into Ventuz Basic 4.7, the model was imported without camera and animation. In your help file there is no mention to Collada format. Why you don't upgrade the manual too? Does exist a simple example to understand how can I import a collada animation scene into Ventuz 4.7? The user Chriss told that with XSI imported a scene with inverse kinematics too (!) into Ventuz, I use 3ds Max 9. Regards    Report

01-21-2008, 14:32 saudade Joined on 03-29-2007 italy Posts 129 Re: Collada animations I installed the latest FBX plugin for Max 9, it saves in Collada format too. Deep Exploration opens the files exported from Max very well with animations. If I try to import a file generated from Max 9 through the FBX plugin Ventuz says: "Import of primitive failed! Can't import polygons with more of 4 sides!" Deep Exploration opens this file very well. I have to re-save this file with Deep Exploration but in Ventuz I don't see any animation. What I have to do?

They are disabled by default. Make sure that 'Rotation->Euler Parameters->Axis Order' is set to 'ZXY' in Max for all objects which are rotated in any kind. Ventuz only uses this rotation order. If you use different rotation orders in Max, the imported animation will look different in Ventuz. Ventuz does not (and will not) support all features and capabilities of COLLADA. For example we can not import n-gons. So always triangulate your meshes before export. We are currently working on the missing and outdated sections in the manual. Best Regards karol    Report

01-24-2008, 13:48 saudade Joined on 03-29-2007 italy Posts 129 Re: Collada animations Attachment: SLIDE1.jpg From about two years I'm asking you to have the possibily to import animated objects. Finally Ventuz has the Collada importer...but doesn't work or probably is buggy. About the 50% of architects, engineers, designers, artist use 3DS Max, and like me, would like to use a 3d realtime software to do presentations. Ok, now we have Collada, but I knew that it works only with XSI exporter. What software you tested? I would like to understand why it's so difficult to import inside Ventuz a so simple scene with two elementary animations. Deep Exploration export very well the Collada format exported from Max, why don't Ventuz????? I have to use Deep Exploration to resave my scene again to be compatible with Ventuz...but inside your software nothing appears. I will attach some screenshots to show you what steps I followed. I hope to read your answer and  I need to have an help because I have to do a presentation. Best regards.    Report

Myself and a couple of other Ventuz users know have been using the Collada importer without ANY problems. I totally understand that you are frustrated because you can't get it to work properly but that is no reason to be so "unfriendly". I downloaded the Maya Collada exporer and immediately got it running. And MAX is not the de facto standard. In my opinion it is the worst of all 3D applications out there. In your screenshots I can see that you are exporting in FBX file format from MAX. Why on earth are you doing this??? Install a proper Collada Exporter for MAX and directly export Collada without using Deep Exploration. I do not know which collada exporters you tested, but i am sure you will not have any problems with the one from Feeling Software (www.feelingsoftware.com). I am using their Collada Exporter for Maya and it works very well. Let me know if this one works or if you need help with it. Krix    Report

But..., you don't know (probably), the Autodesk FBX plugin saves in FBX and DAE format.... I'm not a programmer like you, to use Collada exporter from Feelingsoftware I have to download libraries from Nvidia, that won't install on my 64 XP, then the FCollada tools, then again the plugin, and again compile for my system (!!!!!)....Sorry but I can't learn the programming, I have no time. If I got the right plugin inside Max and it's programmed already by Autodesk I don't understand why Deep Exploration opens perfectly my DAE files and Ventuz doesn't Ok, I can understand that Collada has a lot of options, but I will be happy if anyone will export with succes one single, basic and good animation from Max to Ventuz. Best wishes. Gabriele    Report

01-24-2008, 22:29 saudade Joined on 03-29-2007 italy Posts 129 Re: Collada animations I missed something.... very strange effect....I didn't need the compiler or other Nvidia tools, the Feelingsoftware plugin worked but Deep Exploration didn't visualize any objects, Ventuz did it... Now I see the objects but camera is not on the right position.... Is it possible to add in Ventuz a Max option that use the right axes? Regards    Report

01-24-2008, 23:22 saudade Joined on 03-29-2007 italy Posts 129 Re: Collada animations Conclusions: A) With Feelingsoftware plugin for 3ds Max only the camera is animated. In Ventuz there are no animations for objetcs exported with this plugin and the camera is not in the right XYZ (or ZXY) position I set in Max 9. B) Saving with FBX-DAE Autodesk plugin you can't import the geometry inside Ventuz because you have ngons. You have to use an external program like Deep Exploration that imports very good any geometry from the DAE file, and then you have to export it again...but... C) Deep Exploration doesn't visualize any object exported with Feelingsoftware plugin from Max 9 D) There is no way to export  animated objects and cameras from Max 9 to Ventuz 4.7 using the Collada format Regards.    Report

I will install Max and try that all out myself. :) BTW, I am not a developer. I can code a little bit but it is rather pathetic. I really just installed nVidia CG and the plug-in and it immediately worked. If you have trouble with ngons, does it work when you polygonize the objects before exporting? Krix    Report

01-28-2008, 16:50 Karol Joined on 05-15-2005 Posts 281 Re: Collada animations Hi saudade, We tested the Collada-Export-Import with the Feelingsoftware plugin. But that's not the important point! If you want to import the animation data of objects you have to select 'ByObjectGroup' in the Grouping option of the DAE Import Options. This is crucial! Sorry for the missing section in the Help file. This will be added and will be available with Rev. 4.8. If you import and group objects 'by material' their original hierarchy is discarded. So the animation which is linked to the hierarchy can't be imported anymore. Here is an example: you have an complex robot arm which consists of 100 objects. This arm also has a complex hierarchy but only 3 different materials are assigned to all objects. If you export this arm and try to import it in Ventuz 'by object group' you will get the original hierarchy with 100 objects and 3 materials. If you import it 'by material' you will get only 3 objects with three materials. All objects which had the same material in the original data have been merged to one single object. This option is useful if you have to save rendering performance. In this case only one object has to be rendered and not about 33 (100/3 = 33). In this version the render contex has to be switched 33 times. This costs performance. Please try this at home :) The transparency/alpha problem is a Bug in the Exporter. There are some Collada Exporter which mix up transparency (at least XSI and SketchUp). The Collada transparency specification is a little bit confusing. Mind the Rotation order as I mentioned in my previous post! Max uses a right-handed coordinate system whereas Ventuz uses a left-handed one. Best regards karol    Report
