HeightMap Texture Not Loading / Applying?

[Rolento]

Hi All

I am experimenting with heightmaps and have encountered a strange glitch (but more likely a noob mistake!).  Basically when I use certain image files (supported file formats) for the heightmap and/or texture I discover that the heightmap does not work.  See below:

Test 1: Here I am referencing two files from WikiMedia for the heightmap and texture (SUCCESS)

Test 2: Here I am referencing a different texture file but the same heightmap as above (FAILURE)

I thought the problem might be a permissions / security issue - therefore I did two additional experiments; (a) copied all JS and image files locally and reran the test (failed), and (b) copies the image files on to my own web server and tried to reference them from that location (failed).  Therefore, its possibly an issue with the file format or image format?  So I am left wondering why the texture file in the above example wont work - if anyone can shed some light on this matter I would appreciate - Thanks...

Looks like it was a CORS issue.

Hi Adam

So it appears that (in my case) our Apache webserver is blocking external sites from accessing resources (e.g. image files).  I will investigate to find out how to disable that.

I guess what really confused me was when I copied all image and source JS  files on to my local computer - and then proceeded to run the code, but I still found that the files would not be referenced.  So it appears there is some other security issue occurring when running locally... 

Thanks for your help.
