BUG - Mip Mapped Exr Displacement

[Zach Gray]

Win7 x64 - Build 14240 and pre

Mip mapped exr files read as diffuse textures just fine. Break as displacement.
Displacement works fine if normal (not tiled) exr.

Used exrmaketiled for conversion.

See linked exr files.

We are having the exact same problem when using tiled mipmapped exr for displacement (x64 build 14024) .
I flagged the problem to Vlado few weeks ago, still waiting for a solution.

Any idea on this? I'm a bit stuck with rendering my scenes, I tried reverting back to a previous version, sp1, but that had other problems with normal maps.

Still working on it, but I think it should be fine for the next build tomorrow.

Best regards,
Vlado

I checked 14309, and the changelog

[bug] Crash when using tiled OpenEXR files for displacement - resolved.

I even tried a conversion using img2tiledexr instead of exrmaketiled. Still crashes on my 4k map during vray render. 2010x64.
