Juan Gea (juang3d) added a comment to D2613: Cycles: Implement persistent storage for all scene data.

OK, I did my best to try to update this for 2.81, since it's super important to save render time in big scenes with animation, but it's too advanced for me, I have no idea on how the new depsgraph work at all or how to apply this patch, I went file per file doing the changes manually to each file and trying to adapt it, but I reached a point that things have changed so much that I don't know what to do, my programming level is not so advanced.

Cool, @Martin Felke (scorpion81)! 👍 Looking forward to try the new Remesh modifier. When can we expect it in the Blender master?
Thanks!

True, then the best thing would be to do what you say, focus in finalizing this patch so lights are not transparent :)

Juan Gea (juang3d) added a comment to D5769: Continuation of D3433 - Visible lights in cycles.

Well, I would not clutter UI with fakes that someone may, or may not use. If you don't want to see the light, then you can simply turn off the Camera ray visibility flag. If you want to see the light but don't want it to occlude other lights, then simply turn of Shadow ray visibility flag. All that's really needed here to cover most of the production scenarios is that every single of these flags works correctly with area lights :)

I tried to find where is the alpha of the light managed, but I'm unable to find it, so I'm very curious with your evolution on this patch @Lukas Stockner (lukasstockner97) :)

Juan Gea (juang3d) added a comment to D5769: Continuation of D3433 - Visible lights in cycles.

Well, I agree in that having the light as a opaque object should be the expected behaviour, I imagine that if the problem is that is stacks two lights then one of them should be disabled or at least disable it's emission capabilities, that we we would not have double light, but the alpha should be 1.0 as soon as we make the light visible, at least I cannot imagine any other situation where I could want to have a 0 alpha light.

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.

@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.
