This is one of the joys Microsoft Edge and Explorer. Edge does not support audio formats of the moderne era. I have already relegated Edge to the junk pile so I have not tried this, but you might try some different audio formats.

Hi,
If you scale your object on one or two axis, you should apply scale. If you scale your object on all axis evenly, this is not necessary.



Shortcut: ctrl-A click scale.

Welcome, sounds like you made some great progress for one day!
Have you seen this video on the Project Manager?

From what you say, I wonder if you are using the built in server that starts up with Blender (assuming you have Blend4Web installed). You can use a simple Python server but there is no need with the one that ships with Blend4Web.

Very nice cube. I think the distortion is partially due to how the camera moves. In your sketchfab mode, the camera pivots on its location to look around, similar to the 'Eye' setting in Blend4Web. With the camera in 'Target' mode, the camera pivots around a central target. This means that the camera is in essence, moving side to side which will reveal the 3d aspect of a scene (or lack of 3d in the case of a photosphere). I have chosen this because I insert 3d objecst into my scene and a camera in Eye mode would not show a 3d object, it would appear flat. This is like if you look at a tree with one eye and hold still, you get no 3d perception but if you move side to side you can perceive the depth.

I do map them to a sphere. But in some cases you can alter the shape of the sphere to reduce distortions. For example if your spherical image was taken on a flat plane with no objects like trees or buildings right next to you, flatened out sphere mesh can give good results.
Have a look at this video:

The shape I am describing is shown at about 10:20 in the video.

You can achieve different effects by changing the camera mode to 'Eye' or reducing its range in the 'Target' mode. Also by making your sphere larger it seems to reduce distortions. But you are in effect making a 2 dimensional image on the inside of a sphere and sort of tricking the view to feel like it is 3d. It can look good but it won't be real 3d. There will always be some distortion.

In this project, for the "Home' and 'Main Map' links, I made the letters and the background plane into hot links. There is not much chance to see a glow but the red flags on the map are links that have a glow.

Nice trash drums by the way

Hi trepaning,
You can do it with logic nodes. Look at this video:

wpostma,
In Joomla, can you upload an HTML file?
The most simple thing to do might be export your Blend4Web project from Blender into a self contained HTML document then upload it to your Joomla site. You could also load the HTML file in an iframe.

Hi friends,
I have been busy with a commercial application. This is a fairly simple project that did not require any coding. It is however quite large and I plan to change the model from this prototype version to one that uses code to dynamically load the assets. This app will expand to include spherical photo sets from other dates so it will become unworkable eventually without using dynamic scene loading. As it is now, I use the default player and then load the required JSON scene into it.
See it here.

Hi ben,
Can you attach a .blend file? You can use the "Attach" button when writing your post. Also in Blender go to File > External Data and check "Automatically Pack Into .blend", then save. That way your images will be part of the .blend file.

Also, here is a video where I put an image texture on a sphere at about 5min 30 sec in.
