triplanars in combination with texture refrence objects causing nan/inf errors

Attempted to bake these triplanar nodes with render selection to texture and the nans actually baked into the maps(blue spots). They also dont occur in the same places every time. removing the reference object seems to get rid of them but the reference object is required to stop swimming?

Arnold 5.3 is binary compatible for custom shaders. Custom operators would need to be recompiled.

@Stephen Blair,

Thanks for the response. When is the relese date or Arnold 5.3?
Will it be a smooth transision /upgrade from 5.2.2.1 or will we need to rebuild our shaders?

Kind Regards

triplanar doesn't work with Pref, so you can't expect correct results

If you can wait until Arnold 5.3 is released, there's a fix

Good day Arnold Answers,

I was wondering if you could shed more light on this topic.

Right now our Studio is running on MtoA 3.1.2.1 with Arnold Core 5.2.2.1.
How unstable it the aiTriplanar in Pref at render time?

How unstable it the aiTriplanar in Pref when baked and is there a workaround for the NAN/INF errors?

What version has a working aiTriplanar in Pref?

This implicates our Pipeline decisions and scheduling predictions.

Kind Regards

ok so then if pref doesn't work with the triplanar you can't use it for animating objects?

You can't use it for anything where you want to use pref to prevent swimming

Hey Stephen, thanks for the response. So when you say "pref", do you mean the coordinate space setting? So if this was set to object or world it would work with the texture reference object?

Pref is the reference position that MtoA gets from the texture reference object.

If you use object or world, then you're not using the texture reference object, and you should see texture swimming.
