Feature Request Changing cubemap settings runtime (srgb, mipmap and size)

Hi,

Is it possible to change below settings of Cubemap in runtime?
- sRGB
- Mipmap
- Size

It seems it's not possible and I wonder Unity has any plan for enabling this.

I have a cubemap that is captured in runtime, and want to use it as a reflection probe texture.
(I know there is Realtime type in reflection probe but that will render another cubemap so I don't want it.)

The cubemap is rendered for a different purpose and mipmap is not enabled which disables Standard shader smoothness so I want to change it in runtime.

Thank you

 

It is not possible, because it's not how graphics APIs work.

When you change a texture asset's settings, what's actually happening behind the scenes is that texture on the GPU is being destroyed, and a new one is being created from scratch.

In your case your cubemap is presumably being rendered on the GPU to a cubemap render texture. If you wanted one that had the above alternate settings, the only way to do that would be to create a new cubemap and copy the data from the original one to the new one. This is something you'd want to do anyway if you're planning on using it for a reflection probe on the standard shader, since you'd need to generate the appropriately blurred mip maps.
