Subject: Vue Imports .OBJ Really Small. Why?


LMcLean ( ) posted Sat, 10 March 2007 at 11:34 AM · edited Wed, 15 January 2025 at 5:37 AM

I have made a model in C4D and it is huge, but when I import it into Vue, it comes into Vue really small. Is this because Vue works in Real world measurements? I have created a spaceship in C4D and it is huge. It fills C4D's working area, but it's tiny when imported to Vue. I could leave it small , but Vue's materials will be too large then. Most of the time I just increase the Export size in C4D, but I am wondering if there is another option I am not looking at? Q. Are there any wavefront (.obj.) import options in Vue? My C4D wavefront export options are set to 1000, but I may try to increase it to 10,000 or 100,000 and see if that helps. Just wondering if any of you use C4D and how you work it?

I just made an object in C4D to use in a Vue scene. I left scales in C4D default, which are huge ( a cube in C4D is 200 meters by default in my options), then I exported as 3ds and the size was correct in Vue6 (e.g. huge, really huge); Just tried obj, and the size is correct as well. Are you using real world units in Vue?

I think you must have the units the same on both sides - Vue AND C4D. Then it should work correctly, as Bruno has it.

**LMcLean**: The solution may be down to the object scaling when exported from Cinema -its default value is 1 - adjust as appropriate in Cinemas' edit/preferences menu.

The answer is quite straightforward.

C4D has no concept of real world units - if you have a model 200m by 200m and change the units, all C4D does is change the suffix. 

Vue on the other hand does know about real world units and scales accordingly. If you have set your Vue units to Meters then a C4D object of 200 units will come in at 200m. If on the other hand your Vue units are set to cm, the same C4D model will come in at 2m.

If your models are importing into vue at a very small size, just change the units in Vue to a bigger one.

Steve, if a 200x200 metres cube is exported from C4D, it will load in Vue the same size, so I would say it's important to get the right units in C4D if the main work is to be done in Vue.

Thanks for the tips. let me explain what's going on. C4D wavefront Export is set to 1. (image 01) C4D measurements are in Metres. (image 01) Vue Import scale is set to 1. (image 02) Vue measurements are in Metres also. (image 03) 1. I created a Cube in C4D. 200 metres x 200 metres in size. 2. I then exported it from C4D as a .obj and my wavefront export scale was set to 1 3. I then imported the cube into Vue and only selected "center object". (My Vue measurements were set to "metres default".) 4. My cube which was 200 x 200 metres in C4D is 20 x 20 metres in Vue 6 Inf. Anyone know why it isn't 200 x 200 metres like it should be? What am I missing here?

The cube in C4D is 200 x 200 metres, but when imported to Vue it's only 20 x 20 metres. figure Why the difference?

My Vue units are set to "Metric Automatic". I tried it with straight "mertric" too and the same result. Do you all have this setting set to "Metric Automatic" which is Vue's default or is yours different?


wabe ( ) posted Sun, 11 March 2007 at 9:05 AM

What is when you re-import the obj into Cinema? Or to something else (Poser for example). What size does it have there? And maybe you have another modeller - maybe Blender or Wings3D (to name two free ones) - or Lightwave (I think I know you have that). Does it have the same effect?

What I try to come closer to is wether the problem is in the export filter from Cinema or in the import filter from Vue - in your case.

Now, this is strange, because I have exactly the same settings in C4D and Vue, wavefront export scale is set to 1, and Vue imports at the right scale.

LMcLean: Increase the Cinema object export scale in Cinema - you have it too low. If your objects are only 1/10 of the size they should be in Vue then Change Cinemas' export value to 10. Do the sizes match up then?

Becco_UK Just tried that. I increased the export from 1 to 10 and tried it and the cube came in at 2 x 2 metres. So I will try further tests.

This time I increased C4D's wavefront export from 10 to 100 for a comparison. it seems increasing C4D's export size decreases Vue's import size. (Very Strange) Now the Cube imported into Vue at .02 x .02 metres. I will try Exporting from Cinema at -10 next and see what happens.

Hooray. I finally figured it out! Just set C4D's export to 0.1, then when you import into Vue the cube will come in at the same size. 200 x 200 metres. = : ) Hope this might have helped someone. I know it helped me. Thanks!

LMcLean: You got there in the end - it's very annoying that all these software companies use different scaling.


LMcLean ( ) posted Tue, 13 March 2007 at 1:06 AM

Becco_UK, Yup, I agree can be quite annoying! Thanks for your help!
