All objects on base layer not showing up on layers

Kate - 

By chance did you add a background graphic (shape, image) to your slide layers?

Or, did you format background on a slide layer and fill it with a solid color?

Those are the two most common reasons base layer objects are hidden on slide layers.

Thanks David. I went in to have a look at some of the layers on a few different slides, right clicked on slide, checked format background - and no solid fill. No image either ... is there another way to check for this?

The strange thing is that it has happened to all slides in my module with layers and each layer on a slide - including each individual screen-recording slide and other types of slides with buttons etc - so for example, on the screen recording slides when you get a tip - you see the tip caption on a white screen ... weird. See below in screenshot with a layer open... All base layer objects visible but nothing in them... and what you see on the slide is what you see in publish mode.

Thanks for the info and update, Kate.

Can you try selecting a slide layer and then, in the far left scene column, right clicking the slide thumbnail and changing the slide layout.

If you want to post your .story project, I'm happy to take a look at it.

Thank you so much David.

When I go into a slide layer and right click on a thumbnail to choose layouts - a custom design series of layouts displays. None of them seem to be applied (none of them highlighted). When I select blank from those custom design layouts ... the objects on base layer show up again. I've done this to a few layers on different types of slide interactions and it's the same for all of them.

Then I created a new slide, put a shape on it, and created a layer with a shape, and I can now see the base layer object. The layout for the layer has come from the Custom Design series of layouts and the blank was automatically selected. Before when I tried to do this - the base layer objects didn't show up (and I guess no layout from this series was being applied?).

I did try to customise my feedback master before the issue occurred. I did think it may have caused the issue. So I deleted my custom ones from Feedback Master. Now when I go into Feedback Master, there is one lot of layouts, and the base layer object is called Custom_design and they are the ones that show up when I look at layouts for layers from the thumbnail. But they look like the standard clean version.

Should I go to each slide and reapply a new layout to each layer? Is it okay that my Feedback master Clean version has been replaced with a custom design? 

Thank you so so much - I think you've solved it.... 

It all seems to be working. As I go through and tidy up slides I am reapplying a layout to the layers. You're the best and thank you so much for taking that screencast for me. I'll be more careful next time when working with feedback masters.

Dave you are an absolute genius, the issue has been driving me crazy for weeks, cant believe this was such a simple fix.

My work around was to copy every object of the base layer to each of the new layers for that slide.ha. Thanks again.

Thanks a bunch. This information totally helped me out!

Hi DK! I love when these old posts help others out! Thanks for sharing :)

I was having the exact same issue and it was indeed solved by applying a different slide layout. Thanks!

Hi there - I've just encountered a similar issue - a bunch of random images have vanished from my Storyline course. I can see them in the thumbnails in the Storyline view, but they are not visible in the Slide view, nor when I preview or publish the file. If I view the file Storyline_unsupported.html, I can see the missing graphics. None of the workarounds given in this or other similar threads has worked for me, so I'll lodge a support ticket. Thanks.
