Hi Ryan
Can I make a render region in tiles?
It seems that the “enable tiles rendering” and “enable region rendering” are incopatible, when I turn one on the other comes off.
It would be great to implement this feature! 
Thanks
Mario
Hi Mario,
Currently, we only support one or the other. We’ll add this feature request to the wish list.
Cheers,

Hi Ryan, again…
I thought that the solution to my problem passes for using the “re-render User-defined” and specify the only parts of the image that I want.
But…
I think that the “User-defined Tiles” windows as two major problems. First, the window is to small and can not be resized, if I have many tiles I can not select then. And second (and much worse) the windows as a 4x3 proportion, if I have a hd render (16x9) the tiles do not match the right proportion and are away from they right place!!!
You can and this to the request wish list because this is very important!
If I only select several parts of the image on the “re-render User-defined”, will deadline assemble them on the end or it will be missing all the rest?
Thanks
Mario
If you have rendered all tiles already and then specify Re-Render User-Defined Tiles, the new tiles will be saved at the same location as the existing ones, replacing the previous tiles, then will assemble updated images. If you changed the output filename, obviously the new tiles won’t find the rest and won’t assemble.
The 4x3 proportion should not affect how tiles are rendered. The window loads the last rendered image (if existing) as a preview and guide and STRETCHES is to to fit in the 4x3 aspect, but should still represents correctly what will end up in each tile. It is just a fancy editor to specify a list of tile coordinates (X and Y index) to be passed to the jobs. Of course, picking very small tiles might be a problem - how many tiles do you use in X and Y?
Hi Bobo and Ryan
The “re- render user-defined tiles” option is very good, and I know how it works! 
The problem is that it could be even better! 
The preview window is limit to a 4x3 resolution and it stretch any image that goes out of this. As you may know, no one works any more in 4x3, we are in the HD 16x9 age!
Besides that the window is to small, and can not be resized.
Other great option would be to tell us, as we put the mouse over, which tile we are selecting. On the other day, I had to use this to re-render 2 tiles and it was very difficult to guess that were the tiles that I really wanted!
Another great option would be to select several tiles by dragging the mouse, or by window, instead of picking one by one.
I have to render several very large images, the bigest that max could render (32768px), but I just want a slice of a 16x9 image. So I really want is to render a region in tiles!
I thought I could uses the “re- render user-defined tiles” option to select only the part of the image that I want. As the image is very large I’m thinking of divide in 100 tiles in X, but now I have very small tiles and I will have to select one by one!!!
Do you have any suggestions?
Thanks
Mario
Sounds like a bug.
If the same frame is on, I would have expected it to work with both aspect ratios. It obviously does not.
Keep in mind the whole SMTD is a script and there are certain limitations to what can be done with rollouts and bitmaps in MAXScript.
I will try to make it respect the safe frame, aspect and allow resizing, but it might turn out to be more difficult than it appears.
Also, some better selecting modes would really be useful, including Ctrl+click to always add, Alt+click to always remove tiles, region selection, paint selection etc.
Thanks for the feedback!
Ok! Thanks for taking note of my sugestions
I imagine that it will not be easy, but you with your vast knowledge in MAXScript are the right man to do it!
