32 bit rpf files...

[rfellers]

I've been trying to experiment with some post-processing dof in combustion using rpf files and lenscare. Am I doing something wrong, or is there a bug that will not allow me to save 32-bit rpf files out of max? I am using a Vray sun and sky and VrayPhysicalCamera.

8-bit works fine...

32-bit does not...

Is this a gamma issue? Clamping? Bug?

Thanks in advance,

There was thread in cgtalk about this. If I remember
right, 32 bit rpf is clamped if you import it using
premultiplied alpha. So, if you want to use 32 bit
float rpf in Combustion, you have to build alpha from
other layer.
