[SOLVED] Cube Map error in Chrome

Hello, I am rather new to PlayCanvas, and I have one little question. While uploading texture image to Editor - it’s all fine. Then, I create new Cube Map and try to attach uploaded texture to Cube Map, but Chrome Browser every time give me an error: “Uncaught SecurityError: Failed to execute ‘toDataURL’ on ‘HTMLCanvasElement’: Tainted canvases may not be exported”. It happens with any texture/image on Cube Map. And as the result, I can’t test my app. What can I do to solve this problem, except changing the browser to something like Firefox?
P.S. And, please, sorry for my English :smile:

Hi, could you please share the project url or link to file giving you a trouble?

OK. Draft of this project is public and it’s named “1911”, but it has not published yet. So, I have some good news - if I delete prefiltered data from Cube Map, the app is loading well. But now Cube Map placed on the scene is black, I don’t know why, it looks like reversed normals in Autodesk Maya or something like that. So, please, help me.

I noticed that, in Chrome’s JavaScript console, there are a number of errors when I run your project:

So I looked at your project in WebGL Inspector:

You’ve put the same 1200x765 image onto all six faces of a cube map. This is not the correct way to set up a cube map.

The user manual for cube maps is here:


What the manual page doesn’t seem to say is that each cube face must be power of 2 in dimension and square (32x32, 64x64, 128x128, 256x256, 512x512, etc)

There are a few samples cubemaps already in the PlayCanvas Asset Store. You could simply import one of those if you can’t find any online. Here are some that I found with Google:

Thanks, it was my fault. Last question: how can I attach whole skybox texture to PlayCanvas Cube Map? Or I need to divide it to six square textures and then import to project?

PlayCanvas can’t slice up cross format images into the 6 individual faces for you. You have to upload 6 separate images. Hopefully, the Editor will get the ability to import cross format too some time in the future.
