So what kind of format is *.float and how can I convert an *.exr to *.float?

Oh, I thought a lin to a hdri and indigo tutorial and not just the conversion. The conversion is easy as I already have an exr for hdri...

@fused: could you pls give me the link you were talking about?

@paulo_gomes: That's exactly what I did, but I get the following error:
Fatal Error: ImageExcept: Error encountered while reading RAW image. (In element 'spherical', around line 31, column 9)

blender 2.43

How do I do hdri with kitchen_probe.hdr from the 0.7 test 5 exporter?

@Kram1032: I used no exporter at all as I used the examples, that come with Indigo itself.

@fused: Was that comment for me? If so, where do yo want me to look exactly? Can you pls be a little bit more specific...

I downloaded 0.7 test 5 and tried some of the tests that come with it.

However, it seems to not work with any materials that have an IOR, is that a bug or a feature?
