rendered polarized images are the same with different polarization angle

[jiazhangW]

Hello,

I am rendering polarized images. Basically, I put a linear polarizer in front of the camera. But when I rotate the filter, the rendered images are the same. I attached my xml below. Please correct me if you find anything wrong. Thanks!

<sampler type="ldsampler">
    <integer name="sample_count" value="64" />
</sampler>
<film type="hdrfilm">
    <integer name="width" value="256" />
    <integer name="height" value="256" />
    <rfilter type="gaussian" />
</film>

<transform name="to_world">
    <scale x="10" y="10" z="10"/>
    <translate x="0" y="0" z="-2.9" />
    <rotate x="0" y="0" z="1" angle="90"/>
    <rotate x="1" y="0" z="0" angle="-90"/>

</transform>

Are you sure you're rendering in a polarized mode? E.g. scalar_spectral_polarized?

Yes, I did. Sorry I didn't notice that the attached code is incomplete. But I already solve the problem by checking your previous reply. I didn't specify a material for the conductor bsdf. Thanks!

Hi! @jiazhangW
I am trying to do the same thing as you do. I also put a polarizer in front of the camera to simulate the polarized camera but i meet different problems. Can you please help me figure out why this problem happend? i already opened a issue here #832 (comment), thank you!
