Hi all,

Sorry for my English

Me and my Team using Adobe Dimension for packaging presentation. The program is easy and make an amazing and beautiful rendering picture. But I want to create an advance presentation.

 

So I use .GLB format file from a program sent to Adobe Aero for making an AR and import to Power Point for making 3D presentation. I found some problem. When I place graphic on the translucence body like glass material. When it show on Aero and PowerPoint the transparency is disappear, But the glass body that not place a graphic still translucence.

 

Me and my Team try to do many way but can’t solve it. I want to asked to Supporter did you have some special technic or solution ?

 

I hope that will be useful to us both.

Thank you&Best Regards,

Hi

I've just tested this and to take any other apps out of the equation, I tested exporting and re-importing from and to Dimension.

When I exported and re-imported using GLB the translucence was not re-imported as a map, in the same way that Base color was  (suggesting it had not been exported that way). Instead, on re-importing, translucence was set to 0%

 

 

When I used OBJ format instead, the translucence map was correctly exported and re-imported. On import it looks like this:

 

 

I did a bit of digging and there were suggestions the GLB does not support maps for translucence (which would explain why no map was re-imported) but I've not been able to confirm that definitively.

I like to think of it as the difference between a mirror and a window, they both (normally) made of the same glass material

    Thanks for your answer, Dave.

    May I ask you more question? If I want to use .obj files in Aero and Powerpoint to have the translucence and graphic as intended What methods can I use?

    I don't see any of those balls as being translucence... well maybe the one with no graphic but the very fact there isn't a graphic [or any other difference] makes it pointless anyway

     

    to say something has translucence is to show how the light reacts to the material i.e, is changed as it passes into it

    my example

     

    this ball flips the light, i.e, the logo is upside down on the 'inside' back face... if you can't see a copy of the logo [or any difference at all] then the ball can be transparent [opacity] but not translucence

     

     I'll ask Dave to have a look to because he is a better teacher than me

      Maybe what you told me is correct.

      But because of my language proficiency And an understanding of the differences between translucence and transparent that I still do not fully understand

      For every answer I receive, I will keep it as knowledge and case studies. It will definitely be useful in the future.

      Thank you very much

      does tranparency = translucence?

      if so Mac machines have major trouble with it and the real world fix is to use Windows instead because Microsoft is not having a silly war with Nvidia like Apple is

       

      if transparency = opacity then I assume the error is because you jumped from Dimension to Areo and then into power point which means your Glb file got converted along the way

        Thank you for your advice and yes transparency is translucence.

        I try to use Dimension on window but it not translucence too.

         

        This time I make the sample picture for easy to understand what I mean.

        So what I want it to be is translucence body like D. but have a graphic like B.
