Hi All.
It’s probably been discussed before. Sorry for that.
How is that possible that a lot of native Flame nodes don’t work in 32bits???
I mean it’s impossible to maintain a 32 bits flow graph for more than a few nodes.
Action handles it very nicely but how is it that Comp node doesn’t?
I keep using Actions nodes to make basic operations like subtract or so just because Comp can’t do it (working with ST maps).
Actually, I also use Crock_Logicop that keeps thing in 32 bits but I really don’t understand how native nodes don’t all support 32bits.
Reminds me years back when it was the exact same situation with 16 bits float.
Arghhhhhh!!!
I currently work with a 2023.3 flame on a linux box.
Most of the reason is that 32 bits are overkill for all but a select few specific data passes (UV maps and CryptoMattes) and those data passes should not be filtered.
For images it is functionally impossible to cause a 16 bit image to band up.
Like you can do it, but if you’re doing it you are well outside reasonable behavior.
Mainly 2 things. 1st is the UV Unwrap trick shown here that is really useful in my current project.
2nd thing is not a subtract but I use a UV map to apply a distort to an image and easily keyframe power of the distort by just blending the distorted UV and the untouched UV.
As 32 bits is useful for data passes, I don’t understand why Comp node degrades to 16 bits…
Fair point. It is kind of strange when the “newer” nodes (circa 2013) don’t have the higher functionality.
You could use Actions, but there are like two “no I really mean it!” Safety switches to get them to render 32 bit. I believe one is in the batch prefs, the other in Action itself.
Yep, there are 2 and they are exactly where you said.
I do that with action but it’s (as 32 bits for most cases) a bit overkill to just add or subtract 2 layers.
I mean, I understand that 32 bits are way to much for 90% of the cases but event if all nodes should by default work in 16 bits, we should have the ability to choose to stay in 32bits for certains tasks. We need a switch to allow that, especially for everyday use nodes like Comp!!!
