How To Change the Opacity of An Animated Human Figure?
Hello,
I’ve created an animated human figure in Adobe Fuse/Mixamo. Then I opened it up in C4D and it animates and looks good.
But, what I want to do is reduce the opacity on the figure so that it is semi-transparent throughout the animation. I’ve attempted to apply the Display Tag to all of the elements of the figure and set the display at 70%. However, when I observe the animation in playback and after render it still displays at 100%. How can I adjust the opacity of the animated human figure so that it is semi-transparent throughout the animation?
Thanks!

The Display Tag visibility setting will only affect the rendered image, so you will see no change in the viewport during playback, and you must have Transparency enabled in your Render Settings:

Have a look at the fresnel shader/settings as a transparent option. With straight transparency you don’t get that build up at the edges or where things overlap. But Fresnel adds this volumetric feel to things.

I highlighted all of the elements of the figure and applied the Display Tag set to 60%. Then I made sure that Transparency was enabled in the Render Settings and rendered the animation. After the render was complete, the figure in the render still showed up at 100% opacity even though visibility in the Display Tag was set to 60%.
Any other ideas why it is not displaying as semi-transparent?
Thanks.

Is there something in the background for us to see through to? Unless you have an alpha (and even then I’m not sure) if there is nothing in the background the transparency may not show up the way you think it should.
( you can also just put the display tag on the parent and that will filter down through all the other children unless they have their own display tag) -
Yes. In the C4D file I have a green background. When I view the rendered QuickTime movie the green background is not seen at all through the animated figure. Also, when I import the rendered movie into Final Cut and apply a Keyer to it, the green background is keyed, however, the animated figure appears at 100% opacity with no transparency.

James, can you upload the project file or at least a screenshot of your scene with all of the object hierarchies expanded? That might help us locate the problem.

What is your raytracing depth set to? There might be so many layers that the rays peter out before they get through all the objects.

I haven’t uploaded anything yet in this forum. I’m not sure how to do it and what file size limitations there are.
Please let me know the file upload process and file size limitations. The size of the C4D file is about 16.5 MB. If that’s too big perhaps a screen shot like you suggested might work instead.
Please advise.
Thanks!

The limit is 100mb so you’re well under. Hit the little floppy disk icon above the text entry field when you go to reply (its the last one on the right). Then follow the instructions (which aren’t great) Hit the browse button, choose the file on your drive, then once its found it the file name will appear on the right hand column. Select that file and then hit upload. The system will zip that file and generate a link for you to copy and paste into the text of your reply (choose the top one it gives you of the two to copy) . It will be a link to the file in the forum with HTML stuff around it.
You can close the uploader windows to get back to the reply text entry area and paste it there. -
You can also just drag a file into the message window.
