Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

From the command shell use the flags -tw and -th. The valid value range is between 16

From the command shell use the flags -tw and -th. The valid value range is between 16 and 256 ??

Need more explanationd please
Can anyone help??

The -tw and -th render flags does not divide the final rendered image. It will only affect how big "tiles" the renderer will render at a time during the rendering process. Smaller tile sizes allows larger textures to fit in the RAM. Normally you don't have to touch these...

?

tx 1000 (start point (left corner) of the tile)
ty 1000 (start point (left upper corner) of the tile)

Now you got the left upper corner-point where the tile should start, normally left upper corner is tw 0, th 0


Next thing is to define, how big the tile is (to the right and down-wards)

tw 1000 (=tile width)
th 1000 (=tile height)



so the command for the first quarter is:
render -tx 0 -ty 0 -tw 2000 -th 2000 mySceneName.mb

2nd Q
render -tx 0 -ty 2000 -tw 2000 -th 2000 mySceneName.mb

3nd Q
render -tx 2000 -ty 0 -tw 2000 -th 2000 mySceneName.mb

4nd Q
render -tx 2000 -ty 2000 -tw 2000 -th 2000 mySceneName.mb

Is that not a way do divide my images to get a higher resol for each Q . I don,t understand how maya could render the Q's separatly
Do yu understand wht i mean??

I think you're (or me user added image) mixing regions and tiles. I think you're talking about regions. From the help:

xLeft -xl <int> set X sub-region left pixel boundary of the final image

xRight -xr <int> set X sub-region right pixel boundary of the final image

yLow -yl <int> set Y sub-region low pixel boundary of the final image

yHigh -yh <int> set Y sub-region high pixel boundary of the final image

So if my final resolution is 6000x6000, and with 4 Squares, then:
In command prompt, not in script editor; after closing Maya;



Render -x 6000 -y 6000 -xl 0 -xr 2999 -yl 0 -yh 2999 -im lower_left myfile.mb
Render -x 6000 -y 6000 -xl 0 -xr 2999 -yl 3000 -yh 5999 -im upper_left myfile.mb
Render -x 6000 -y 6000 -xl 3000 -xr 5999 -yl 0 -yh 2999 -im lower_right myfile.mb
Render -x 6000 -y 6000 -xl 3000 -xr 5999 -yl 3000 -yh 5999 -im upper_right myfile.mb





"Render -x 6000 -y 6000 -xl 0 -xr 2999 -yl 0 -yh 2999 -im lower_left" C:\ "Documents and Settings" \ "filou" \ "trial" \ "balls.mb"

"Render -x 6000 -y 6000 -xr 2999 -xl 2999 -yh 2999 -yl 0 -im lower_left"'
n'est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.

Which means:


"Render -x 6000 -y 6000 -xr 2999 -xl 2999 -yh 2999 -yl 0 -im lower_left"'
is not recognize as an intern or extern command or(?) an executive programm.....

Please help

Got it ,at the end with c:\tmp

Quotes " and spaces for first part of the command and then:



C:\temp\myfile.mb !!!

But , how would you name 6 or 8 different squares??
