Juan Gea (juang3d) added a comment to T68914: Cycles adaptive subdivision.

What is this about? An improvement, a confirmation or a recovery of part of the 2.79 adaptive displacement?

Juan Gea (juang3d) added a comment to T60695: Optimized per-datablock global undo.

Undo is bad in both, this is not a regression, any complex file makes undo nearly a torture to use. Just animating a camera for example, you are just transforming the camera, and making undo in a big scene takes A LOT instead of being instantaneous as it should be

Yes, I have not found the problem yet, still looking at particles code when I have some time, I would like to do some proper debug and profiling as Antonio did to find if I found the bottleneck, but I don't think it's a bug, it's just something to be improved.

I'm afraid this is not an inestability problem, I mean... it is, but it's not a bug, it's due to defaults being wrong, and also the haird collision system not being the best in the world, it's not too precise.

Juan Gea (juang3d) added a comment to T65133: Selection not snapping to mesh generated from curves with modifiers.

@Germano Cavalcante (mano-wii) well, right now this is a pretty important feature, I'm not sure what areas do you think that need more attention in snapping, could be great to know :) (really, no pun intented) but a common workflow in any software is to snap things to curves, since for example CAD data come in curve form and some parts of a CAD model may be constructed based on the CAD curve to allow an easy iteration.

Juan Gea (juang3d) added a comment to T65228: Quick Fur particles enter in infinite loop and crash.

It seems to be related to some kind of capping, with 100.000 particles * 100 interpolated children all CPU's are being used ina multithreaded task, while with 100.000 * 10 interpolated children it seems that is not running the multithreading, so it's doing a single threaded task

Juan Gea (juang3d) added a comment to T65228: Quick Fur particles enter in infinite loop and crash.

ok, so in 2.8 is also working, so this may be just the result of having faster particle creation and now having a much slower children creation, which in reality it's not slower, it's that now it's more obvious, I'm not sure, still doing some more tests though

@Sam Van Hulle (sam_vh) probably what you want is a blue noise distribution pattern, this will give the impression of random and organic but at the same time will give the particles evenly distirbuted without forming clumps, somethign that now happens, I wish this could be implemented
