funny that the speed difference is almost exactly a factor of two ... did you perhaps use 1 thread on linux and 2 on windows ?

the tex index means multiple .exr for 'env maps' if desired?
Hmm, the background and env-map XML code will stick around for now.

Yes, you can do all kinds of crazy sh*t like multiple env map textures, or even use shaders for the background if you want :)

I did some little experiment about render speed at my computer, and tbh im really suprised
As dougal2 said, please check you are using the same number of threads in both tests. The speeds of the linux build and windows build should be pretty similar.

Have a look in log.txt, just before it starts rendering.

Make sure that the Indigo folder is not write protected; the svn folders can be safely discarded.

Look in the manual in the renderer settings section, the option called num_threads. The number of threads used is specified in the output/log when the scene has finished loading, and before the render starts.

ok ono done that or at least 1st approximation - now what about the lat-long case...
what is the xml for that please - or is that still coming?

called it Skymap until I remove the old stuff ;)

edit:2nd approx :)
edit:3rd approx :D

ok no.4 ;)
attach also here is a simple scruffy trial render with a shader used as a background - this is ono's grid shader from the 'shader' thread
not sure why it started out with a bright square in it though :?:
possibly will hard code this in with some settings for grid size..

Looks like for me that you are stuck, Anthor, by luck I'm no expert in that field :) And I'm of no help at all if you use linux, but you'd have said 'root' not admin !? Maybe setting application paths in linux is trickier

I presume you can find this line into the <renderer_settings> section of the igs file:
<logging>true</logging>
or Indigo would not look for it... :?

Despite admin rights, I believe you should check the write access of the folder Indigo resides in (right-click on the folder > properties. admin access doesn't remove write protection byte), some portable drives might mark their content protected by default when coping it out ...

Well that's just a hint, never heard about this error before.

Well i can confirm problem with logging - i deleted log.txt, it reappeared but message was still the same - cant open for writing. And log.txt is always empty.
