HI! Is there any possible to write real time denoiser algorithm for every graphics card?

zebus3d

I managed to do more or less what I wanted. I know my patch won't be accepted because of my rookie code, but I'm proud of it!

HAY Pablo, And Dalai ,, Is there any other experimental builds apart from particle nodes

Have you guys thought about adding an RBF( Radial Basis Function) Solver to Blender, it's a great solution for complex 3 axes rotations..?

In the episode with Ian, I was so happy to hear you say "EEVEE motion blur in 2.9" that I wrote it all over my walls in my apartment. Can't go back now!

Joking aside, glad to see EEVEE motion blur getting pushed up a little more on the priority list, and perhaps onto the road map. In animation EEVEE is becoming a legitimate force and motion blur is a must. Thank you Blender Foundation and devs for all the hard work! :)

How's Multires refactoring going? Any news on new booleans? Any plans for Quadriflow update, so it actually could handle hard edges?

Hello. I'm interested why documentation of blender is so limited and almost without any visual examples explaining how things work it would be very helpfull? Is it because all learning should be obtained from blender cloud? If people would like to volunteer and contribute documenting and connecting references to the features (F1) how could they join? Pablo Dobarro makes such a wonderful short videos explaining sculpt features, something like this could be used in documentation it would be great help for people. Also features like edge slide have undocumented shortcuts like E or Alt how to find info like this? Are features like those hardcoded ?

Hi Pablo oh man blender is awesome! I was using 3DS max for 10+ years and its nothing but a blessing to have made the switch to blender. Thanks to all the teams great great work!

My question, I would like to use an .ai file or similar vector graphic (.pdf, svg) as an image texture... to benefit from its infinite scalability? is that possible somehow?

Thanks J

Hi Pablo! Hi Dalai! Hi Blender development Team. You're awesome!

Last time on "Dive into the code" stream I learned sooo much new! Thank you!

The question: why doesn't blender have "Displace" modifier for curves? It is easy!

Just add "eModifierTypeFlag_AcceptsCVs" flag! And it'll perfectly displace curves along X, Y or Z-axis. Take a look at the picture.

Cheers! Stay safe and sound!

P.S. Okay, okay, I know the answer... "Everything Nodes" :D :D {attachment 456876JPG}

Testers: Are you looking for testers? I am not talking about using blender as a artists and bug reporting but as a scripter thoroughly testing a particular change from a daily build for example. I know about posting in the forums but ... Not me so much. Would a developer like a tester etc?

Hi * @lets4done * !

Testers are always needed! Please meet us at #blendercoders to see how we could organize it.

** Precision Modeling + Some Suggestions

Hi Pablo!

Many people would like to use Blender for everyday task like 3D printing, design ecc.

  • Are planned new features for CAD modeling, precision drawing or to enhance the curves workflow?

  • I would suggest to enhance two tools: the wireframe modifier and inset operator.

Wireframe modifier , how is actually, in my opinion those wedges are ugly: wedges

better, both aesthetically and topologically in particular when adding a subd modifier: better

The inset operator : I would suggest to add an option to obtain the second topology, especially useful in archiviz:

inset

  • In some layout configuration (without the navigation widget for example) the negative and positive axis are indistinguishable. Their color is customizable in some way (maybe via Python)?

axis

thank you!!

* @Mille Porte * 1. topologically second one have 8* 2. new vertices. If you want to use it for fremes, try solidify+rimMask+solidify.

Hey! When can we expect another blog post? I also love reading these! Thanks!

When are you going to fix the equirectangular render for grease pencil?

​Is there an option to add a video to the material?

Image Image Hello Blender developers thanks for all your time and efforts put into Blender. Let me jump to the question right away.

Can we have something similar to EEVEE, which is a fast way to get acceptable results, to generate some effects like in "Effekseer 1.5" project. It is open-source too. May be looking at this project blender team can get some ideas to implement in future. (extension to or Addition to everything nodes?)

Please check "Toon Effects" made with Effelseer 1.5 to understand my question better. Such effects possibility will compliment "Grease Pencil" and Game developers.

Thank you once again.

* @Bharat * Generate — it is for addon. Achieve same look — yes, EEVEE, NPR (shader to RGB)

Hello Dalai, hello Pablo! Please answer, is it difficuilt task to make zebra-stripes in keymap? Small change, but much more usable keytab.

{attachment 1a46354019f74d83ac8aa968f08c5941-hjpg}

Old request, and ppl like it: blender.community/c/rightclickselect/CDcbbc/

And is the second thing difficuilt: rearange modifier`s buttons in strict vertical rows. picture and explanation: {attachment 78ac4893c7ed45c98ef35519bfc3db3d-ljpg} blender.community/c/rightclickselect/tsdbbc/ (HOT topic)

is there any particular technicality that prevents the developers to integrate luxcore by default (as an in-built addon)?

Pablo <3 Can we expect faster compositor anytime soon or any updates? Autotrack addon was awesome tool for VFX guys till 2.79... it got ported as 3rd party addon but is bugged, why its so underrated?

Hey youuuuu guuuuys, just wondering if there are any thoughts on replacing blenders data structure with USD in future? Looks extremely performant, and would also solve the undo issue:

This shot has 80 thousand Mesh and 52 Million polygon include Cloth simluation And Rigs just 3 second To open and Real Time shaders

Pablo, which mic do you use for these streams?

Hi * @3d illusions * !

It seems like the original question has been altered. so this answer does not match with the question anymore.

For EEVEE there are two options. In EEVEE the shader nodes are written in glsl files. For each shader tree these files are merged into a larger one (one per material). Adding custom glsl files here might technically complex as we need to preparse the glsl files to see how it connects within the shader tree.

What most users want is to write a shader fully outside of eevee, but that would also mean that all features that eevee provides will not work with this shader. For example lighting, shadows, refraction etc.

Cycles shaders are written in SVM (Shader Virtual Machine) what is Cycles specific and OSL. OSL will eventually support GPU other render engines are working on this. When that released publically we might be able incorporate it in Cycles. We first need to see how GPU based OSL will look like before saying anything about how feasible it is.

Hi * @3d illusions *

USD is very promising, but remember that the video you are referring to is an animation cached played back with very limited shaders. All the animations you see were baked, not sure how that video is representable to what you would want for Blender to have.

* @Jeroen Bakker * Thanks dude.

Rockbard

Hey, Pablo. My question is about the "Disable and keep transform" function for the IK constraint Any progress in this area? If I understand right this function could serve as an IK/FK switch, right? This will make IK/FK switch setup tremendously easer.

Also, any plans for the weight mirror function? Current version returning very strange results. Thanks!

sybren

* @Buster Friendly * Hi Buster. I made the "Disable and keep transform" button, but I don't have any plans to work on getting it to work on IK constraints. The reason is that disabling an IK constraint requires adjusting other bones as well, and not just the constrained bone.

Rockbard

* @Sybren Stüvel * Hi, Sybren. Thank you for the work and the quick response, Maybe other devs will come up with any ideas idk.

sensenku

Hi Pable, I have 2 questions:

  1. When will Shadow pass introduce shadows of objects in Compositing?
  2. Will Blender 3MF file format? (Because it's Free-Opensource with some advantages)
DolphinDream

Can anyone fix the annotation line thickness issue on mac? currently linewidth larger than 1px does not work, making the annotations a bit useless (too thin to see on retina displays)

Buttabean

Is it possible to have manta flow show the baking process in the viewport as it bakes? I find myself hitting cancel to see if anything is causing problems.

Dantewei

A professor here, there's a way to have a small blender for computers of the year 2000? Or a kid version ?? to put on schools with old computers ?? Also mac user, with toch bar the f(n) keys do not apear

wannes.malfait

Hi. I would love to see more video's about blenders code base in the future. Is there a reason why you can't split the viewport into one part object mode and the other edit mode?

phucthai936

I have 2 question:

  1. Why i have 2 shading (Color of Water) but In the render view it doesn't same. Blender 2.8 (Same every thing, Cycles, no texture, ....)
  2. Can Blender next update make more dark?

(I think it a bug or something can you inbox me at phucthai936@gmai.com)

Hello guys! Are there any plans on vanilla blender's animation tools?

virtualanubismaster

Please bring WEIGHT PAINTING back to 2.79 functionality, it's VISIBILITY in 2.8 isn't great .. (Flat View in 2.79 for weightpaint was essential ) Performance is slow because of all the things you have to do to make it visible

At-Mind

Hi * @virtualanubismaster * !

Have you tried the changes I did last few weeks. Please download a daily build and see for yourself.

adrian.newton1066

For the 2.90 Modifiers, shouldn't the Render/Viewport icons be the other way around?

adamadam

Hello! A number of people are having viewport performance problems with 2019-2020 Icelake based laptop CPUs running Blender 2.8x. I was wondering if you were aware of this and if so is there a plan to rectify? Thanks.

At-Mind

Hi * @adamadam *

I have been working on this topic. If you try the daily builds from today you would see that it is a lot faster. I hope to be able to spend more time to improve the performance even more.

You can follow developer.blender.org/T70922 if you want to be up-to-date with all the updates.

reston.stanton

Hi

Any plans for the file browser?

Better python API for the file browser?

Thanks

alex.mitov

Hello guys!

Chaos Group are currently trying to develop V-ray for Blender 2.8x. Are you guys in contact with them to help facilitate this? From what I read in their forum, that they were trying to get in contact with someone from the Blender development team to help with this.

I think that the integration of Vray with Blender 2.8x will be another HUGE boost for Blender's reputation and image as a 3D software for not only enthusiast, but also professionals. It will drive enormous amounts of new users and potential supporters, me included.

Thanks and stay safe!

How can I help on translations for Blender?

rbx775

Hi Pablo & Dalai ! Is it possible to apply an initial rotational force to a physic object. Like it is already rotating at the first simulated frame?

BarfGarbage

Hey guys, for how long will new versions of blender be released as frequently as it has been since 2.80? Will it be a new version every three months until forever or will it revert back to the dark ages with twice a year?

atomizer1001

Will the 2.83 release included with better inbuilt QUADRIFLOW and RETOPOLOGY?

koahku

Hey! So I use a lot of addons from a lot of different places and managing them is a bit tedious. Have there ever been plans to create something like a package manager for addons that would allow someone to update them all with a single click, that sort of thing?

nussscheibe

Is there a possibility to apply the influence of a forcefield to a mesh/volume?

rbx775

Hi Pablo! Love all the Developers Q&A guests! Can we also have one with Clement for EEVEE questions? :)

virtualanubismaster

Please improve Weight Painting , it's very uncomfortable in 2.8 , i always have to go back to 2.79 :(

vanshtyagiharyanvi

Hi Pablo, Actually my question is may be in future updates or next update we get a feature to export Mesh with UV AND Materials to Unity or Unreal. Becs sometimes working with UV,s is soo difficult.
