Povray rendering error

[egon]

I attempt to render to a povray file and get the following:

Error: can't read "render_command_param": no such variable.

The text of the error shows:


can't read "render_command_param": no such variable
can't read "render_command_param": no such variable
while executing
"set ns " $render_command_param""
invoked from within
".render.f.ok invoke"
("uplevel" body line 1)
invoked from within
"uplevel #0 [list $w invoke]"
(procedure "tk::ButtonUp" line 22)
invoked from within
"tk::ButtonUp .render.f.ok"
(command bound to event)


Any hints or ideas?

Is this on Windows or Linux?

Please post the contents of the other fields in the render dialog.

This is on linux. The other fields are:

Output file type: Povray
Output filename: ac3dpovfile.pov
Render program: povray
Render parameters: +UV +UL +A0.2 +FT32 &

I've just had a look at the code and it looks like there is a bug that shows if you don't put a %s in the render parameters.

So - please could you try adding a %s in the render parameters and trying that (you will need it anyway - this is where AC3D inserts the filename for povray).

This bug is in tcl/ac3drender.tcl:

# if render comand is not empty, look for %s and replace %s with the render_filename
if { $prefs_render_command_param != "" } {
set pos [string first "%s" $prefs_render_command_param]
set pos1 [expr $pos + 1]

if { $pos != -1 } {
set ns [string replace $prefs_render_command_param $pos $pos1 $prefs_render_filename]
} else {
set ns " $render_command_param"
}
} else {
set ns ""
}

The bold text should be $prefs_render_command_param
