I want to render custom cubemaps for some of my reflection probes. When I attempt to run the Wizard (Unity - Scripting API: Camera.RenderToCubemap) and place an existing cubemap into the slot and click Render, I get the error:
Unable to render into cubemap, make sure it’s marked as ‘Readable’, and it fails
How so I “make sure it’s marked as ‘Readable’”? I am on Windows 7 Unity 5.3.3 pro
I duplicated an existing cubemap, so it would not be “in use”, but I still get the error.
Creating a new cubemap (in Wizard) doesn’t fail, but I need to save it to be able to reuse it.
Do I have to create a new cubemap and save it? How do I save it (in c#)?
Seems like a configuration issue, but how do I fix this?
BTW: my files are set for full access
Thanks,
Doug
