I have been trying to get to the bottom of why my Flood Fill node is taking 12+ seconds to process. I compared it to someone else's graph, and the only obvious difference is the bit level of the node. We are both using the latest version of Designer. We compared our settings for the node and couldn't find any obvious…
I checked an older graph of mine and copied the flood fill node from it. Here they are side by side: I can find no obvious difference in settings between the two, except that the older (bottom) node doesn't have anything inside the Instance Parameters section, while the newer (upper) node has a Safety/Speed trade-off drop…
The performance drop seems to be due to the fact that the GPU engine is running out of memory with the new Fill node on your machine. The new Fill node requires to use multiple C32f textures internally, which at 4k resolution quickly fills up most graphics cards VRAM. Since the shapes you are working on at this stage in…
Graphs can be hidden from the library - they've done it with the AO node and afaik most of the noises - you can unhide them with a button on the node attributes panel if you want them listed.
They did actually change flood fill so that'll be a bug I should think. If you contact Allegorithmic support directly they should be able to advise you on what exactly to do. In the meantime.. You'll be able to find the original flood fill node in the install directory where the rest of the packages are stored. They don't…
I'm telling you, I took the C16 node from my old graph, plugged it into my new graph, and it produced the exact same result as the C32F node in three orders of magnitude less time. Anyways, I filed a bug report so we'll see what comes of it.
We're working on a fix that reduces the memory cost (and consequently brings the performance back to something more reasonable at 4K) for the for new node for the next bug fix release. It will also make the output C16 as it should.
It's a different node, the old one doesn't have the same sums in. What I showed you above is the new one, altered to allow for changes in bit depth not working if you don't give it signed values.
