Have you tried to enable legacy mode(multi layer) of exr? I have to check this option in most case to see those aovs in nuke.

I'm trying to render a 150 degree fisheye with the physicallens shader, tweaking the quadratic distortion type(curvature at 0.51), don't know how to match the same result as the equidistant projection(150 degree), the best result I can get is a similar render checking with eye.
Is there any tips? thanks anyway.

Is karma physicallens made with vex? if so, is it posible to add the fisheye mode to it?
#pragma opname fishLens #pragma oplabel "Fisheye Lens" #pragma hint x hidden #pragma hint y hidden #pragma hint P hidden #pragma hint I hidden #pragma hint valid hidden //CUSTOM #pragma lable fov "Fov" #pragma range fov 0 180 #include "math.h" cvex fisheye_lens( /*equiangular fisheye lens shader with adjustable FOV and circular image format*/ // Inputs float x = 0; float y = 0; // Outputs export vector P = 0; export vector I = 0; export int valid = 0; // Shader arguments float fov = 180.0; ) { float radius = sqrt(x*x+y*y); /*calculate distance from center of image plane*/ /*following if statement means I is only computed inside r<=1, so that areas of image outside circular format aren't rendered*/ if (radius <= 1){ /*using 1.0 produces blurriness(bug?), but 1.01 works fine*/ float phi = atan2(y,x); float theta = radians(fov/2.0 * radius); I = set(sin(theta)*cos(phi),sin(theta)*sin(phi),cos(theta)); valid = 1; } }

Hi, can we make fisheye lens shader working in karma xpu 1.0? since physicallens is working, how to render a 180 degree fisheye image?
Thanks for any help.

This chart shows what is in Karma CPU and Karma XPU compared to Mantra:

Xpu does not surpport (Cvex)Lens Shader for now, will it be surpported in the near future?

Hi,everyone
I am very distressed for rendering the Deep Output file,that is very big ,
Now,how to compress it ? I am used to do rendering for exr or rat.
thank you! thank you everybody!
