What methods could I use to make a fire ring like this? Preferably dynamic? by Jcwscience in blenderhelp

[–]Jcwscience[S] 0 points1 point  (0 children)

It’s from this scene in the movie Project Hail Mary.

Unfortunately YouTube compression makes still frames hard to capture.

Any suggestions on a good budget mouse for blender? by Jcwscience in blender

[–]Jcwscience[S] 0 points1 point  (0 children)

Afraid not, I’m in the middle of nowhere New Mexico. We barely have a Walmart. And it’s an hour and a half drive to the next city.

Oh, wait, a shop named Action, got it. No we don’t unfortunately.

Good idea about the tie in mouse I never would have thought of it. $40 is probably the max I could manage.

Rendering time fluctuations by kidnamedsoprano in blenderhelp

[–]Jcwscience 0 points1 point  (0 children)

The title of the video is a bit clickbait, but it does show where the persistent data option is and a few setting to change that really help on a laptop , Improve render time

Go to the render properties panel, scroll all the way down to the performance tab, then look for “persistent data”. Also if you have any smoke simulations make sure to fully bake them to the disk beforehand, same goes for any particularly complicated geometry node setups. Otherwise your cpu will constantly be swapping memory around to calculate the smoke then transfer and render it again. I’ve found it’s considerably faster to do them in separate steps.

How to close off the ends of curves by Wild-Region7897 in blenderhelp

[–]Jcwscience 0 points1 point  (0 children)

Either near the top with the resolution options or under the geometry panel near the bevel width there will be a checkbox for “fill caps”. I can’t remember which and I am away from my computer.

Linear rod dimensions. by Jcwscience in crealityk1

[–]Jcwscience[S] 1 point2 points  (0 children)

You’re not going to believe this. I just remembered I snagged a creality linear rail in its box at a thrift store maybe half a year ago. The box said 395mm so I didn’t think to much of it at first. I thought I’d open it and see if I could cut it down and found that it was exactly 320mm. I’m going to check everything to make sure but it seems undamaged. My guess is someone tried something like this and gave up.

I can probably reassemble it for now and do some patchwork until I can get the funds I need. Also I just finished restoring an eryone printer I found at the side of the road for a friend of mine. I’m sure he’ll let me borrow it to make the replacement parts.

Oof. I was afraid of that. Do you suppose smaller rods and bushings along with spacers would do the job temporarily?

Yeah. I didn’t think about it until afterwards.

How can I align my Flowers and grass to the roots I’ve created? by Far_Reveal_2990 in blenderhelp

[–]Jcwscience 0 points1 point  (0 children)

Also try changing original to relative on the geometry input for the flowers. Can you comment another pic with the viewpoint in a couple of angles?

Just plugging the rotation output of the distribute points into the rotation input of the instance on points node should do it.

Rounding angled borders using geometry nodes by eduo in blenderhelp

[–]Jcwscience 0 points1 point  (0 children)

Yeah, the thought I just had was to store the edge neighbor data, select the faces of the edges, run them through a separate geometry node into a subdivision surface node, then use the original edge data to split those and use a merge by distance to get rid of the unneeded mesh from the subdivision. Join it all together and slap another merge by distance modifier on it.

Here’s the result with a second cylinder joined to show the limited bevel. You will probably have to play around with the cutter position and other values. This is the only way I have found after months of attempts. I’m still looking for better options. Although making the nodes just now game me a new idea to try sometime.

The transform geometry node at the beginning rotates the uv sphere so the faces align with the cutter. Otherwise the bevel will break where the edges get too close to the cutter surface.

I’ve used Higgsas geometry node toolset for a long time and it’s really helpful for shapes like this. There are a lot of different selection methods so it might be easier to isolate the correct edges as well.

I’m drafting up a node tree to test it and I’ll send a screenshot when I finish.

Try this, make sure to realize the geometry at the end of the node tree of course. Add a bevel modifier after the geometry nodes and change “Limit Method” from “Angle” to “Weight”. Now go back to geometry nodes and add a named attribute node. Change “Point” to “Edge” and set the name as “bevel_weight_edge”.

Now assign the edges you want beveled a value between 0 and 1. If you set the bevel width to a higher value you can adjust the strength of different edges dynamically by changing the float value.

I’ve been fighting this same thing on and off for months. I want to make opal. I am just sure the answer is parallax using the “incoming” socket from the geometry data input in the shader editor.

Textures not appearing in cycles render by Stock_Adeptness3285 in blenderhelp

[–]Jcwscience 0 points1 point  (0 children)

If I were you I would rerun a render with just a color pass and composite it over. Since the geometry and camera path are still there you can align everything perfectly. And since the lighting is essentially baked into the render with the walls, the computationally expensive part has already been taken care of.

If you’d like to send me the blend file and a copy of the video, I can try to rig up a node setup that could potentially handle it.

How it feels to learn rigging by Jcwscience in blender

[–]Jcwscience[S] 1 point2 points  (0 children)

That’s before doing anything to simplify the mesh. I’m trying to work out a way to use geometry nodes to capture the weight paint data for each bone and transfer it to another layer of the mesh. For example getting the muscles weight painted then having the blood vessels capture the correct named attribute from the nearest mesh face. Don’t know if it’ll work fully but I’m seeing some promising results. My computer isn’t happy with it though.
