Indigo Renderer Forum

Hi all,
We've been working on improving the IES support in Indigo.
A wider range of IES files are now supported, and some IES parsing problems have been fixed. Indigo should now be able to load any somewhat reasonable IES file.

We've also done some work on optimising the rendering when using IES lights, especially for spotlight-type IES files - see the example renders below. Both renders took 30 s. The top image uses the new IES improvements.

Well done Nik! Such a vast improvement on sampling IES is really a great news!

Looking good, but at the slight expense of samples/sec?

This are great improvements and together with the general light sampling enhancements you brought Indigo to the next level.
Congratulations and thanks a lot!!

A better result with less samples
quantity != quality

Great! Any enhancement to IES is welcome!

One question: Is it possible to rotate the IES light? E.g. to the ceiling? or toward to a wall?

Can you post the code?

Thank you.

Its simply controlled by the normal direction of the polygon that emits it... afaik.

Now that is nice !!!

Looking good! Is that example done with plain pathtracing?

Great improvements!

I would bet it only improves the bidirectionnal mode

Etienne is right on the money, as always
