Hi
I am starting PovRay from another application with following command:
%povray% /EDIT Test1.pov /RENDER Test1.pov
where %povray% is
C:\Programme\POV_Ray\POV-Ray 3.7\bin\pvengine.exe
or
C:\Programme\POV_Ray\POV-Ray 3.7\bin\pvengine-sse2.exe
>>> case 1: If PovRay is NOT running, it will be started and following
error message will be displayed:
----------------------------------------------------
IO Restrictions prohibit write access to 'Test1.png'
Failed to start render: Cannot open file.
----------------------------------------------------
But 'Test1.png' doesn't exist - it's the file PovRay should create!!!
>>> case 2: If PovRay is already running, it will display 'Test1.pov'
and start rendering as expected.
I was testing the same situation with PovRay 3.62.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PovRay 3.62 does not show an error messages!
It works perfect in both cases!!!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here are my preferences I set before ...
- Menu: Options / * Keep single instance
- set '+FN' to command line option field to save PNG pictures
And here's the test file I use
-----------------------------------
// File: Test1.pov
camera {location -3*z}
light_source {<9,9,-9> 1 parallel}
sphere {0 1 pigment {rgb<1,1,0.5>}}
-----------------------------------

Yes, and that is exactly what the error message says: It cannot _write_ that
file.

Well, does it have IO restrictions enabled?

Do you mean 'Options / Script I/O-Restrictions' ?
Its' set to * Allow Read, Restrict Write
If I set it to * No Restrictions I'll get this errror message:
----------------------------------------------------------------------
Possible Parse Error: Cannot find file 'Test1.pov', even after trying
to append file type extension.
----------------------------------------------------------------------
Parse Error: Cannot open input file.
Render failed
----------------------------------------------------------------------
And again if PovRay is still running it's working fine without any error
message.
That all is confusing me...
Shouldn't 'Script I/O-Restrictions' only belong to script handling ?
But the 1st error message belongs to the picture file handling.
