Hi! Sorry for the delay. Which version of Blender are you using? Unfortunately I haven't had time to update it to recent releases yet

This is very old! I have another video that uses more modern methods here: ruclips.net/video/nzyz_AyM6oQ/видео.html

@@blendergilads5796 it worked, instead of using colorramp node, use float curve node

Thanks! This is old though, there's better ways to do this now. See for example this ruclips.net/video/nzyz_AyM6oQ/видео.html

Hi! B-renderon respects the output file settings in your scene. If you want to change it from B-renderon side, the extra arguments window offers some common parameters but you can add your own (for example in this case --render-format OPEN_EXR). You can also save yours as presets. That said, OPEN_EXR has indeed been added as a builtin parameter in the upcoming update, for which there's already builds available.

@@blendergilads5796 Oh that's good to know! So if I were to add a project to B-Renderon and not set any frame ranges, output, or extra arguments, would it just use the scene default then?

@@Kaeden_Hahn Yes exactly. That's the main workflow, when you have your scene ready just drop it in B-renderon and click render. The options are there to make it easy to change parameters without affecting the original blend, but users don't need to change anything unless they want to.

@@blendergilads5796 Great, thank you for this! This addon is a real game changer!

how to use LANPR ?

To use a material you need to add a "set material" node. If you need UVs you can generate them procedurally. One way would be to capture the curve factor of the rolling curve (the one that conects to the curve to mesh node as curve) and the curve factor for the quadrilaterla, and with a combine xyz node set those as x and y coordinates respectively and store that as a named attribute.

Use a "set material node"

@@blendergilads5796 Thanks.

Ah you don't need to enter edit mode to create shape attributes actually. Here I was demonstrating the convert shape key to shape attribute functionality but it also has a direct shape attributes saving functionality. For the time being it doesn't use the evaluated mesh though, so not sure if it will help in your case. There's another operator in the add-on that does use the evaluated geometry, aimed at baking animations to attributes, but maybe that one could be of use to you? The initial version of this add-on is available (free) here: blenderartists.org/t/shape-attributes-geometry-nodes-alternative-to-shape-keys-add-on/1465167

I think I had seen your project before, interesting stuff!

@@blendergilads5796 If that does what I think it does (Saves the entire thing as a new shape attribute), that'd be *incredibly* useful for saving specific characters and creatures, like "orc", and "werewolf".

@@eclecticgamer5144 Yes, sounds like it would work for that. If you try it let me know. I'd also like to expand functionalities to cover more workflows so if it isn't suited for that use case for some reason, I'd like to try to make it work.

@@blendergilads5796 Oh man, that would absolutely be awesome! I'll definitely try it out later this week.

Thank you!

Thanks, I'm working on it, I'll share it soon hopeefully

there's an initial version released now, you can download it here: blenderartists.org/t/shape-attributes-geometry-nodes-alternative-to-shape-keys-add-on/1465167

@@blendergilads5796 thank you! I can’t wait to try ..

Instead of chaining several fillet curve nodes, try using only one but in poly mode, then the higher the count the more rounded it will look. Also make sure to use an appropriately high count in the resample node so it looks smooth, and if the profile is not looking smooth try also raising the resolution of the circle that you use as a profile in the curve to mesh node

Thanks a lot!! Very glad it helped

Thank you! yes, there are several ways. Generally I like to use the float curve node to handle easing and simple bounces and overshoot. I show something like that here: ruclips.net/video/nzyz_AyM6oQ/видео.html In this case you might not want to make it overshoot but the same principles apply, the float curve node lets you visually remap the factor that is driving the animation

Thans a lot! It's essentially the same afaik, maybe a tiny performance/memory advantage to using boolean since it's always treated as a boolean and not as a float, but I don't think it would be noticeable. Regarding the math formula, I explained my reasoning in the video, but it's not perfect. The ideal would be to have a transformation from a straight line to a spiral, that keeps the length constant, and starts rolling from one extreme with a min radius and keep that fixed.

@@blendergilads5796 thanks ♥️

There are ways but they're a bit involved currently. For example, you can have the bones follow empty objects with constraints, and parent the empties to vertices of the mesh with vertex parenting. Then the armature does respond to this shapes attributes that I'm using here. What you are saying sounds different though. Changing a geometry nodes slider acording to the pose of a bone is a bit more simple, using the reverse of the method I just mentioned: you parent empties to bones and then bring those empties as objects in the geometry nodes setup with an object info node. But I'm not sure I'm understanding correctly what you intend to do.

​@@blendergilads5796 So the two things are separate but ideal work in tandem The GN 'shapekey' sliders would work with a model thats posed. atm if you make a 'shapekey' from a model in its base pose then enable the shapekey then pose the model the shapekey overrides the pose Would your suggested method be automatable or it it just too complex The posed model would have vertex groups of the bones sot hats a way to do the parent thing of the bone to the vertices? The the second part is to make a pose in pose mode then 'save' that pose so that a GN 0-1 slider can set that pose, which i was thinking the GN slider is just responsible for driving the bones to make the pose just like you can do with real shapekey sliders in blender by default The idea is I 'save' a bunch of poses so GN can have sliders for each pose where the slider goes from base pose to the set pose we can mix and blend poses with different sliders set. The we have a bunch of shapekeys available these would have all been saved under the base pose, so make having GN modify the model into a pose after the shapekeys Do you have a discord i might be rambling too much on here lol

@@speaker6060 Actually with the current way I'm doing thins shape keys are not overriding poses. That happened because in the previous method we set the absolute position to the one stored with attributes, now I'm setting an offset while subtracting the basis shape, so now it respects poses. One thing I was thinking was adding an operator to bake poses/animations to atributes. So the add-on would create a copy of the mesh and save a new attribute per frame in a set range and automatically create a nodegroup that animated between those attributes.

@@blendergilads5796 Ah sweet thats good to hear, makes things easier

You can chain the mix nodes, and for the factors, use different map range nodes with clamp on. So say you want to change between 4 shapes controlling it with a value between 1 and 4. You can plug the value to a map range that maps from 1 to 1.9 to 0-1, and connect that to the first mix factor, and in parallel to that map range another map range that maps from 2 - 2.9 to 0 - 1 and feed that to the second mix node factor, etc. In my latest video ("turning a bird into a flying flock of birds) I mix between three shapes (see around Minute 4:00). That's a bit of a special case because it's fed with a sine node but maybe the example helps clarify the logic a bit. Let me know if that's clear

@@blendergilads5796 I made need a picture, tried to follow but isnt working The idea is to have them blend when each are set to a value just as real shapekeys do

@@speaker6060 Ah I misunderstood your question before. In that case instead of using mix nodes you should use vector math add nodes and since those don't have a factor, you add a vector math scale node to each "shape key" and that controls the factor for each shape. One thing to notice, since we are saving and setting absolute positions of vertices, you need to subtract the base shape every time you add a shape, otherwise the mesh will grow. Here I uploaded a quick and untidy example of what I'm saying: imgur.com/IJ25RVd (You could alternatively save the relative shapes instead, with the base already subtracted, to avoid subtracting each time)

@@blendergilads5796 Hay just saw this, its working perfectly now, this is amazing We can now have instanced meshes that can also use there own shapekeys separate from eachother. If i need to edit the base mesh it updates to all instances. Perfect! I wonder if an addon/script could be made to automate this, like add and option to the shapekey menu to convert to attributes. That would be alot smoother of a workflow for sure. Anyway thakyou so much for showing this off!!!

@@speaker6060 Yeah, I might make a little add-on to simplify this. Though I'm sure a native solution will come not too long from now. For example, the "node operators" devs have been talking about would probably help.

Thanks a lot for your comment! Sorry I wasn't that clear about radius. In the map range node I show around minute 7, the To Min value defines the radius, and the to max should then be set in relation to that and the rug thickness so there's no empty space between the folds

@@blendergilads5796 appreciate the quick answer, as i am still trying to figure it out. That's the value i had in mind too, but if you change the To Min to anything other than 1, the mesh starts to deform and loses it aspect ratio, as it gets rolled up. So it's not really working this way. Do you have any other idea to influence the radius of the roll? Without having to have a 20 m long curve.

@@RomanJahns Ah that's right. Let me check

@@RomanJahns I checked it. To add radius control you can do this: Add a value node to define the radius. Add a math multiply node after the map range node to multiply it's value by the radius. Also plug the radius value to the subtract node that feeds the z component of the combine node, replacing the current 1 value. And finally, add a reroute to the links that feed the sine and cosine so you can change both at the same time, and divide the value that's fed to both by the radius. Then the to max value needs to be adjusted to avoid empty space. A bit hard to explain in a short message so let me know if it's clear. Otherwise I could upload a file.

@@blendergilads5796 simply amazing! Works perfectly! And it's a pretty powerful setup. you should maybe consider releasing an updated video including this feature. Thanks a lot for your quick Response!

Hi! This video is very outdated. In more recent versions you indeed select scenes from a list. Check the B-renderon page on blender market to see current screenshots

​@@blendergilads5796 Awesome! I am checking it right now.

Thanks a lot for your comment!

Thanks! That's a good point. I'll try to make some time to adjust that

Hi! this was never published but I expect to release an updated version soon

Hi! In 3.5 there's a selection socket in the store named attribute (also an exists socket in the named attribute node) so you can mask the parts you save the position of. Another possibility that works in 3.4 also is that each "shapekey" except the base one has the vertices it doesn't mean to affect collapsed at the origin, and then apply each shape key by adding the base to a mix between the shape key and 0,0,0, the fac of that mix working as the shapekey factor.

ahh nevermind i figured it out! wasnt in edit mode haha. thanks for great tutorial!

@@redmiqo Glad you figured out! Sorry if I go a bit quick, I struggle a bit with English so I try to keep the videos short.

@@blendergilads5796 no worries i can follow it! theres just so many little things to keep track of with blender :) love it though

Thanks! It's a bit outdated though (for 2.93), thankfully we now have the string to curves node. I made an updated video for 3.0+ ruclips.net/video/nzyz_AyM6oQ/видео.html

Hi! You need to use a curve with enough subdivisions for it to be able to fold. An alternative to the resample node would be a subdivide curve node, maybe that's better for your case?

@@blendergilads5796 Thanks for the reply. I've tried subdividing the curve multiple times before and I believe its simply the property of bezier curves in particular interpolation that prevents the roll effect unlike a poly spline where the control points are evenly distributed. I have one more question regarding controlling the animation if you dont mind answering. I'd like to draw more than one curve but I'd have to keep duplicating empties which makes this process not very procedural. Do you know another way to control the transformation that relies on something like vertex groups and not empties? Or maybe a mesh primitive within geometry nodes that can do what the empty does? Thanks.

@@tsun8267 I used an empty because I like the convenience of animating an object in the viewport, but you can control by value directly by just not using the object info -> separate nodes that bring the x location of the emtpy in my setup.

@@blendergilads5796 Sorry for the late reply but I was hoping there may be a way to drive it similar to an empty but in this case the empty is outside geometry nodes. Thought perhaps there may be an internal way such as creating an object within geometry nodes that can act as the empty. However I don't think GN can do that at the moment.
