I'm sorry to resurrect a 5 years-old thread, but Sean is correct. Blender exports bad UVs.

a RenderResult contains a list of RenderLayer's (rr->layers)
a RenderLayer contains a list of RenderPass'es (rl->passes)
The naming is exactly what EXR wants. See https://github.com/martijnberger/blender/blob/c359343f8dae6689c955dc1fa700cb26f6cd2e95/source/blender/render/intern/source/render_result.c#L176

Hi James,

Hi johantri, I'm not sure what your question is. If you're uncomfortable using diff/patch you can just apply it by hand, editing render_result.c, and hope it didn't change too much in 1.5 years. Then re-compile Blender (which is too complicated to explain here).
Re-reading the code, it should work with any format (except maybe some exr variants ?). Please let me know if PNG doesn't work.

Hi; this is my first patch on Blender. Please bear with me, esp. if it's not the right place to do code reviews (IRC ?).

Still present in 2.72b.

I can confirm the problem on Windows at least (Win7 64b, VS 1013, latest git tip)
It's the first time ever I look at Blender's source code, but it looks like it has nothing to do with videos or VSE.
One of the "Follow Track" constraints data was deleted and not set to NULL, and deleted again, thus crashing in BKE_constraint_free_data during the undo.
