Hi John,

'oconv materials.rad test.rad > test.oct'

still produces the error message 'xform: cannot find file...'

I have added a screenshot (error1) to the folder below:

https://www.dropbox.com/sh/uyokuvxiu9s1ifb/AAB5TXbez6p8-FAgl3EeR4f2a

With regards to 'objview' I don't actually have that program.

I downloaded a windows version of radiance from the link below and it wasn't included.

Hi Thomas

'rad test.rif' runs and produces and HDR file but it is completely black.

'xform test.rad > test_combined.rad' again gives an error that it can't find the file 'test.rad' which is clearly at the location.

I have put a screenshot of the error into the my dropbox folder (error2)

https://www.dropbox.com/sh/uyokuvxiu9s1ifb/AAB5TXbez6p8-FAgl3EeR4f2a

The huge number of materials was because I had previously imported some DAYSIM results. These have now been purged off an the export files updated.

Hi Ross,

You need to include the materials file in the oconv command, and have it before the geometry. Try:

oconv materials.rad test.rad > test.oct

or, to view the scene 'on the fly':

objview materials.rad test.rad

For a beginner it's usually easier to use the rad command with the *.rif file to get scenes rendered.

$ rad test.rif

That will start rendering all scenes and create the images - in your case only one.

However, looking at the *.rif file I see that there is a warning at the end:

## total number of objects too large

Unfortunately I don't remember why I put this message there. There may be a built-in limit for oconv or another process in Radiance. What happens if you combine all the output files to a single file with the xform command?

xform test.rad > test_combined.rad

If this works you can run oconv with the test_combined.rad file:

oconv test_combined.rad > test.oct

BTW: Is there a specific reason to have so many materials in your scene?
Most of your scene files contain only a few polygons. You can also try to export the scene by group or by layer in su2rad. That (probably) reduces the file count and can solve your problem.

Regards,
Thomas

Hi,

I am now looking to use radiance after learning daysim. I have
successfully completed the tutorial and am now looking to produce
renders from scenes set up in SketchUp.

Here is a link to the SketchUp output file:

Dropbox - Error - Simplify your life

My approach is to apply the OCONV function to the ?test.rad? file.

However unlike in the tutorial, materials and geometry are housed in
separate directories.

And I get the following errors:

oconv test.rad > test.oct

xform: cannot find file "objects/Material133.rad"

oconv: warning - (!xform objects/Material133.rad): empty file

I don?t quite understand why the file can?t be found.

Am I using the correct approach?

Thanks in advance for your help.

Ross,

Ah, I (wrongly) assumed you were using UNIX (linux or Mac).

I was surprised at the number of individual materials / rad files until I used objview and saw that this is how results can be displayed: as a false-colour 'grid' with each tile having its own material (i.e. shade) and rad file.

Yes, if you try to run oconv on the contents of the objects directory it will complain: "oconv: internal - too many scene files".

Ross,

I think this is because you don't have the current working directory in
your RAYPATH.
This is a fault in the instructions on setting RAYPATH on NREL's installer
page. I'd tell you how to rectify it, but I personally don't know how to
indicate current working directory in a Windows environment variable (on
*nix systems it's a period). a work around is to use the whole path in the
rad file (starting with c:) but you have a space in one of your directory
names, so you'd have to do something to escape the space (on *nix it's a
backslash before the space - Don't know if it's the same on Windows).

Can any Windows Radiance user help with including the current working
directory in RAYPATH?

Andy

If you install the latest open studio version, it will install radiance with
the necessary settings, then you do not need to set the paths manually.

Hmm, I thought the dot worked on Win, too. This is why we have that direction on the OpenStudio page. But then again, I recall writing the Radiance translator so that it makes references to scene files like so:

!xform ./scene/shading_building.rad
!xform ./scene/shading_site.rad

So I guess somewhere along the way I found the dot to be lacking.

Perhaps it's time to update that page, eh? Thanks for the heads up, Andy. Oh, and yeah the backslash escapes the space in the filename on Windows too.

P.S.
This may be a breadcrumb trail for someone to follow, if interested in reliably referencing the CWD in your Windows environments:

Ross,

I think this is because you don't have the current working directory in your RAYPATH.
This is a fault in the instructions on setting RAYPATH on NREL's installer page. I'd tell you how to rectify it, but I personally don't know how to indicate current working directory in a Windows environment variable (on *nix systems it's a period). a work around is to use the whole path in the rad file (starting with c:) but you have a space in one of your directory names, so you'd have to do something to escape the space (on *nix it's a backslash before the space - Don't know if it's the same on Windows).

Can any Windows Radiance user help with including the current working directory in RAYPATH?

Hi John,

'oconv materials.rad test.rad > test.oct'

still produces the error message 'xform: cannot find file...'

I have added a screenshot (error1) to the folder below:

https://www.dropbox.com/sh/uyokuvxiu9s1ifb/AAB5TXbez6p8-FAgl3EeR4f2a

With regards to 'objview' I don't actually have that program.

I downloaded a windows version of radiance from the link below and it wasn't included.

Message 2

Hi Thomas

'rad test.rif' runs and produces and HDR file but it is completely black.

'xform test.rad > test_combined.rad' again gives an error that it can't find the file 'test.rad' which is clearly at the location.

I have put a screenshot of the error into the my dropbox folder (error2)

https://www.dropbox.com/sh/uyokuvxiu9s1ifb/AAB5TXbez6p8-FAgl3EeR4f2a

The huge number of materials was because I had previously imported some DAYSIM results. These have now been purged off an the export files updated.

Hi Ross,

You need to include the materials file in the oconv command, and have it before the geometry. Try:

oconv materials.rad test.rad > test.oct

or, to view the scene 'on the fly':

objview materials.rad test.rad

Cheers

For a beginner it's usually easier to use the rad command with the *.rif file to get scenes rendered.

$ rad test.rif

That will start rendering all scenes and create the images - in your case only one.

However, looking at the *.rif file I see that there is a warning at the end:

## total number of objects too large

Unfortunately I don't remember why I put this message there. There may be a built-in limit for oconv or another process in Radiance. What happens if you combine all the output files to a single file with the xform command?

xform test.rad > test_combined.rad

If this works you can run oconv with the test_combined.rad file:

oconv test_combined.rad > test.oct

BTW: Is there a specific reason to have so many materials in your scene?
Most of your scene files contain only a few polygons. You can also try to export the scene by group or by layer in su2rad. That (probably) reduces the file count and can solve your problem.

Regards,
Thomas

Hi,

I am now looking to use radiance after learning daysim. I have
successfully completed the tutorial and am now looking to produce
renders from scenes set up in SketchUp.

Here is a link to the SketchUp output file:

Dropbox - Error - Simplify your life

My approach is to apply the OCONV function to the ?test.rad? file.

However unlike in the tutorial, materials and geometry are housed in
separate directories.

And I get the following errors:

oconv test.rad > test.oct

xform: cannot find file "objects/Material133.rad"

oconv: warning - (!xform objects/Material133.rad): empty file

I don?t quite understand why the file can?t be found.

Am I using the correct approach?

Thanks in advance for your help.
