We have trouble making flame read exrs.
Are there know channel name problems?
So first guess that channel names RGBA are good
A, 32-bit floating-point, sampling 1 1
B, 32-bit floating-point, sampling 1 1
G, 32-bit floating-point, sampling 1 1
R, 32-bit floating-point, sampling 1 1
and these arent:
DiffuseDirect.b, 32-bit floating-point, sampling 1 1
DiffuseDirect.g, 32-bit floating-point, sampling 1 1
DiffuseDirect.r, 32-bit floating-point, sampling 1 1
