That is what I tried, but /RENDER accepts only single argument. Passing
"/RENDER model.pov povray.ini" ends with povray's error message and failure to
do the task.

New test: Unfortunately, this is very tricky. "/EXIT model.pov" does not read
povray.ini in the model directory while "/RENDER model.pov" does. Uff. Luckily,
/EXIT accepts more arguments, so I can safely pass "/EXIT model.pov povray.ini".
So, both of them can work for me.

Although it is tricky, I can go through.

Can I do it programmatically? I expect "stupid" users that are able just to
install povray and click on a button in our application. I expect that they are
not able to do any customization of povray.

I see. This gui is actually too complicated for our customers. All they want is
one pov-ray button and to see pov-ray generated image. We are very very happy
with povray on Linux. Do not worry that we will not give POV-Ray a credit.

You are right - I expected that what I see is error message, but it is only a
dialog about "One instance *feature*". Hm, the dialog actually blocks the
rendering... and POV-Ray is kept running after the rendering...

Yes, but this is what I do not want. This advice is actually not for me (I am
advanced IT person etc.) but for our users, thus it should be given to doc or I
should visit each person and tell him this.

Seems, that there is no way to minimize it programmatically...


I am from far happy with linux povray. I guess the reasons why you want to keep
POV-Ray gui on Windows. Maybe, the possible compromise could be to enhance the
command line.

Anyway, povray is cool, I am just struggling with its interface.
