Assuming your radiance installation is in C:\Radiance, you should place the cal file in the c:\radiance\lib folder. At runtime Radiance searches for .cal files in the folder specified by RAYPATH , which usually is the c:\radiance\lib.

You have a couple of options:

1. Place the file also in the lib folder.

2. Hardcode the full path name instead of keeping it relative i.e. something like c:\project\images\surfpic2.png instead of surfpic2.png .

By the way, did you write your own cal file ?!

I didn't get the 2. point ( hardcode the full...)

no, I got it from Relux Software. I am not able where the .pic files are saved there so i can copy them to radiance folder...

Can you tell me which material it is ? My Relux is in English and I can't see a material by that name in my materials list.

Texture Library, Miscellaneous, then Glass 01

I am not exactly sure what Relux is doing with Radiance. I think it is running Radiance within a process from C++ and lot of the functionality is actually hidden from the users. You can find the cal files and rad files in this folder :

C:\Users\Sarith\AppData\Local\Temp\radSources  (replace my name with yours).

However, the pic file which is created in that folder crashes. So, I tried to hack the process and get an image through a screenshot and ra_bmp.

This is the rendering that I got through Relux:

This is what I got from my own renderings with image that I got:

This is surprising because the material is called Glass. However the radiance definition of the material is :

void colorpict mat_104~1
9 red green blue surfpic2.pic alignpic.cal tile_u tile_v -s 0.58500
0
1 0.975

mat_104~1 plastic mat_104
0
0
5 1 1 1 0 0

The colorpict on the the first line only modifies color patterns and does not make the material transparent/translucent. Similarly, the plastic type implies that the material won't be transparent anyway.

I don't think this material as defined in Relux is a physically based material. You are probably better off importing the Raytracer materials to Honeybee. Andy Mcneil had an excellent presentation about GlassBlocks in the last Radiance workshop: http://www.radiance-online.org/community/workshops/2015-philadelphi...

The pic file that I generated is here : https://www.dropbox.com/s/5c32layqehdns72/surfpic2.pic?dl=0
