Hammer doesn't like it when I use HDR skyboxes.

[JoeKars]

I get this specific error every time I use a skybox that has HDR properties like sky_gravel_01 (the one I want to use) according to the sky list on the developer wiki. I don't get this error when I use a non HDR skybox like sky_badlands_01 (the one I've been using to avoid the error thus far)

Here is the error from the compiler:

*** Error: Skybox vtf files for skybox/sky_gravel_01 weren't compiled with the same size texture and/or same flags!
Can't load skybox file skybox/sky_gravel_01 to build the default cubemap!
*** Error: Skybox vtf files for skybox/sky_gravel_01 weren't compiled with the same size texture and/or same flags!
Can't load skybox file skybox/sky_gravel_01 to build the default cubemap!

I used the interlopers.net error checker and the solution offered by it from this forum post seems very complex and doing things I'm not sure I'm comfortable doing to my game files.

If anyone has another way to fix this or a better way of explaining how to do the forum fix I'd really appreciate it.

This error you can ignore. It happens to everyone and doesn't actually mean anything. Don't worry about it

Well now I feel a little silly cause my map loads it just fine.
Thanks for clarifying that, otherwise I don't think I would have figured it out.
