Feedback Disabling clamping for HDR textures

Feature request: it would be nice if there's an option in texture importer to disable clamping between 0 and 1 for hdr textures even if current color space is gamma. For example, I have a custom height map generated for rendering terrains, which is in EXR format. I'm targeting mobile devices, so I have to choose gamma color space, but Unity clamps my values to 0 and 1, which makes it unusable.

 

You can select the texture in the assets folder and set the "Wrap Mode" to "Repeat" in the inspector. If you can't select it because it gets generated at runtime, you can call

myTexture.WrapMode = TextureWrapMode.Repeat;

 

I'm talking about Unity changing my values in my EXR texture into numbers between 0 and 1, but I need negative values for my shader to work. It's heightmap data used for water rendering.

 

I'm currently using a bug to prevent Unity clamping my values:
1. Change color space in player setting to Linear
2. Uncheck Auto Graphics API
3. Check Auto Graphics API
4. Change color space back to Gamma

You'll see all HDR textures being reimported without values being clamped. It would be really nice if the editor gives me an option to uncheck "clamp between 0 and 1" in texture import options instead of using this bug.

 

Just reviving an old topic because debugging why my loaded textures had incorrect values took up most of my day. It's very strange unity has built in methods to export to EXR, a format that seems purpose built for HDR, if on import it's going to throw away all values above and below the 0 to 1 range.
