changelog:

* fixed EXR environment maps being mirrored horizontally.
* changed external IOR for phong materials back to one because it was causing some crazy artifacts.
* misc other changes for linux build.

nice -

first to post!

[OnoSendai]

lol, first post!!! woo!!

Everyone - Please let me know of any bugs.

[CoolColJ]

BTW what did the changed External IOR actually do? Supposed to improve something?

[OnoSendai]

CCJ: read the test 8 post for some info on it.

[CoolColJ]

BTW you need to update changelog in the test 9 archive

[OnoSendai]

yeah, oh well

[CoolColJ]

Ok I read that explanation of the external IOR for Phong

That's probably why I was seeing some weird stuff with my reflective phong objects in water, in the parts under water

Are you going to try to find another way around the issue later on?

[OnoSendai]

Yes that's what was causing the underwater phong errors.

Not sure when i'll try to fix it, it's probably a pretty subtle effect anyway.

HI Ono,

thanks for this new rel. 09.9 still have some problems with blending specular material (like to following one). Any chances to have this fixed?

Thanks in advance, Riccardo.

Hi rgigante,
it's forbidden to blend two specular materials together in Indigo

[rgigante]

Thanks ono... please just to be sure everybody is aware, add a little note into the manual at the blend material section.


Regards, riccardo.

[OnoSendai]

It's in the 0.9 WIP manual believe it or not

"
There is one restriction that applies to what materials can be blended together (in the same blend
tree composed of one or more blend materials) – At most one constituent material can be a BSDF
containing a delta distribution. Materials with delta distributions are the specular and null_material
material types.

Thanks a million Ono.
Sorry to bug you with this old chestnut (if one can do that), but could you give us a bit of a state of play on the chances to get MPD, problems, limitations, complications...?

Added win 64 bit build.
