I'm using generated texture images to set the individual colors, emission strengths, and sizes of 119,617 stars imported from the Hipparcos catalog. My texture images are each a single row of 119,617 pixels and I'm wondering if Blender will accept it without capping it at certain maximum.
(I noticed in the Texture tab that when I select the texture image, its x-size shows as ~65,000 (going by memory), and that while I can decrease this number, I cannot increase it. This has made me suspect that there is a size limit that I hadn't thought of.)
Thanks in advance if you know the answer and are willing to share it. I'd like to work with even more particles (millions, if Blender will allow me), so size limits of this sort are definitely something I should be aware of!
EDIT: I realize now that the ~65,000 limit appears on Mac OS but not on Windows. The same model that on Windows correctly shows 119,617 pixels for the X dimension of the texture image shows only 65536 on my MacBook Pro. Wondering why that would be? V2.78 on Windows and 2.76 on Mac.
