Wrong Point from Camera information in V-RayMtl Refraction

[flat]

When "Affect alpha" of Refraction is set to "All channels" in VrayMtl, the Point from Camera information [blue channel] of SamplerInfoElements does not output the correct value.

Point from Camera [blue channel] is multiplied by -1 and used as depth information.

Confirmed with V-Ray 3.60 and Next for 3dsMax

I sent a sample etc. (ticket number is: 163-314-2594) Was this problem confirmed by CHAOS GROUP?

Thanks for the report, you may be onto something. A question - what is the reason for not using the Z-Depth channel instead?

This is for use in compositing work.
