IV2018: Studio Rendering Of Fade Animation Not The Same As Preview

[Anonymous]

Hey All,

I'm not exactly sure what's going on here. I've got an assembly which I'm trying to render an animation of in Inventor Studio. The animation starts by immediately fading out all of the parts in the assembly so that I can essentially start the final render at 1s for example and fade in the parts piece by piece as they would be assembled. The preview looks correct as far as visibility goes, however, when I go to render, many of the parts that were faded out appear in the rendering anyway. Once the keyframe in which that part is meant to fade in is reached, the part will disappear and slowly appear again just as the animation was meant to do. I'll render a brief example of this in a moment and follow up on this post if needed.

So, for example, let's just say:

                 Time: 0s-------1s--------2s---2.5s----3s-----

Part1.Visibility: 100%---0%-------0%--50%--100%---

And yet when I go to render, Part 1 is visible from 1s to 2s and then disappears and fades back in from 2s to 3s. So the second behavior is correct, but the part should not be visible from 1s to 2s. Hope this makes sense.

Has anyone else experienced this?

I hesitate to attach Inventor files due to the proprietary nature of what I'm working on so if we can discuss the solution without having to attach files, that would be great.

Thanks in advance,

Hello @Anonymous you might try setting the initial Fade of the part to be 0% Instantaneous at 0 seconds.

Then you can create a 0% to 100% Fade from 0-3 seconds. It should start off and then fade in. 

Hope that gets you going!

Unfortunately I’ve tried that. I’ve tried both the instantaneous fade and the fade out (over 1s) method but the parts still show when I hit render when they’re not supposed to be there.

Thank you for your reply though.

@Anonymous have you installed the most recent Inventor Updates?

Can you repeat this on a dummy model? If you can attach the files with Pack & Go that would be helpful.

So long as the latest update is 2018.3.1, then yes. I recently installed them to see if that would fix the issue. So far that hasn't done the trick.

As for a dummy model, I'll see if I can recreate the issue after I'm done with what I'm working on. For the time being, I've got a method I'm going to try in order to fix the issue in post. I'll post back on here when I can.

Thanks again for your time.

I need to issue a correction @kelly.young. I said "So far that done the trick". Left out the word "hasn't". So far that hasn't done the trick. I've still got the same visibility issues.

Hi Will Mann, 

This issue may be related to override appearance. Here is possible workaround solution.

1. Open the assembly and find the part which cannot be rendered correctly
2. Open the part and go to Appearance browser, double click the Active Appearance for editing, edit any parameters and revert changes, click OK to save the Appearance. Save this part
3. Now, do render with Inventor Studio. See it works or not. 

Here is my email, rui.wang@autodesk.com. Please share your data if you still have such issue. Thanks a lot. 

Thanks,

-Rui
