To normalize the position coordinates of particles for an Image Texture node, I have to divide 1 by a very large number (119,617). After running some tests, I see that the colors of my image texture are off by a factor of about 1e-4 (0.0001).
This has me wondering: how many decimal places does the Math node retain in its output?
I've noticed that some fields (e.g., the values for a
Divide operation) accept up to three decimal places (and that everything beyond that third decimal place is simply rounded up or down). Is the same true for the output of the Math node? If so, is there anyway to change the output precision so that I get at least 6 decimal places in my output?
Many thanks if you know the answer and care to share it!
EDIT: Jaroslav pointed out that color is shown in the
Data-Blocks view of the Outliner panel with six decimal places. However, when I look at the same view of my outliner, I see only three decimal places. Compare my screenshot (below) to that posted by Jaroslav. This is under Blendfile Data > Images > StarCol > Pixels.
Is there a reason for this difference? Am I looking in the wrong place in the
Data-Blocks view? Can I trust that under the hood the full RGBA color values are being used (at least to six decimal places)? I would post this in a separate question, but as I'm only asking for clarification, it seemed best to do it here. Thanks again!
EDIT 2: The Python output for the pixel color values, on the other hand, has far more decimal places than just six! I assume that the values shown in the Outliner panel and in the fields of the Math node are shown with three decimal places for conciseness only? It would be disappointing to have the full precision stored in the Blender file and not using it!
