Is there a "transmission_exit_color" in Arnold 5?

[flow001]

Hi guys,

sorry if this has been asked before, but I couldn't find anything... What I'm trying to do is setup a few (translucent) objects that will exit to a specific (per object) color when exceeding the rops raydepth. This was easy to do in Arnold 4 by simply setting a refraction exit color in the standard shader and turning off "exit to environment" - now in Arnold 5 there is still the checkbox to turn of "exit to environment", but as there is no exit_color slot it will just turn black... Is that expected behaviour? Am I missing something? In the docs (on standard_surface) I found this :

Exit to Background

Specify whether to use the environment color for reflection rays where there was insufficient ray depth (true), or the color specified by reflection_exit_color (false).

But I'm guessing this is a leftover from Arnold 4 as there is no "reflection_exit_color" either...

So, is it possible to exit to a color? I couldn't find it in any plugin I tried (mtoa,sitoa,htoa)

Updated the description. Thanks for the feedback!

Thanks Lee, so there is no way to exit to a custom color anymore?

[flow001]

By the way - if you are at correcting the docs, the next part about "indirect diffuse" is just a duplicate of the "exit to background" section...

Indirect Diffuse

This will cause the Standard Surface shader to trace a ray against the background/environment when the maximum GI reflection/refraction depth is met and return the color that is visible in the background/environment in that direction. When the option is disabled, the path is terminated instead and returns black when the maximum depth is reached.

seems to be a glitch there as well 😉

Cheers!

I don't see that. Can you post a link, please?

Just following your-description-link .... this is what it looks like (at least on my end - hope this is not some website-caching-issue 😉 😞

[lee_griggs]

Fixed. Thanks again!

@Lee Griggs sorry, but I have to ask again: Am I right to assume, that there is no way of assigning a custom exit color per object in Arnold 5? That's very sad, as in some cases it would allow us to use a lower raydepth with just little impact on the look.

[lee_griggs]

Not that I know of.

That's really a pity I hope that "feature" finds it's way back into the core sometime. Kinda hard to belief I'm the only one missing it

Anyway, thanks for clearing that up
