Problem (the button in the following image to add 360 image/video is not appearing)
You may come across this problem with the new VR project/360 image feature within Captivate 2019, where you see the 360 image/video button appearing on most of your machines and on some machines it just fails to load and blank white slide appears.
Before you look for other solutions, I would advise everyone facing the issue to do a basic check on their machines to check whether WebGL (basic pre-requisite to have 360 content working within Captivate) is able to run properly on their machines or not.
What is WebGL?
The problem may arise when your browser does not support WebGL or when your browser does support WebGL but you do not have the required hardware/GPU feature to run WebGL without problems.
What to check?
To verify the same open a responsive project , add a web object within Captivate and add the following link :
Now in the frame loading the link you shall see the following :
If you see the above message, you are good to go, and Add 360 image/video will appear on your system without problems.
