Mantaflow: bake always crashes, cannot be resumed

After realizing that there's no problem if I use Uni Cache (what I usually avoid) instead of OpenVDB I've found an answer myself even for OpenVDB. I don't know why nobody else is experiencing these ...

How to create a realistic looking Ink spill from a bottle?

You could also try volumetrics and an image texture. Use an image texture for the color bleed Give your ink spill a Glass Shader and a Principled Volume shader Use a texture to drive the volume's ...

Should I be changing temperature min and max or reaction speed if I want my flames to go higher?

A high Fuel value will bring more fuel and make higher (but also bigger and more agitated) flames. A low Reaction Speed will speed up the reaction and make higher flames as well. To make higher flames ...

Blender - Quick Liquid - Domain is a glass cube

Quick Liquid does 2 things. 1. It sets up a domain object (some cube-like shape) around the currently selected object. It gives this object a default glass material and sets it to be displayed as a ...

Simple water ball simulation?

I agree with Allen Simpson - use a shader something like this for the "water ball" (object is just a simple sphere). Use a Value Node with #frame entered in the field to make the value match ...

How to create a realistic looking Ink spill from a bottle?

Here the resource-intensive approach with a Fluid simulation and Dynamic Paint for running ink on paper (Eevee render). The fluid is a brush and paints on the paper plane. The setup is similar as ...

Manage water flow with Arduino

Blender could interact with Arduino, because Blender has Python API. You could use Pyserial to communicate with your Arduino via serial connection through USB. You would need to install this external ...

Dynamic Paint on Mantaflow Fluid Simulation doesn't work well to create wet map

Timesteps and Substeps in fluid sim are aiming to prevent from leaking due calculation, but result is frame by frame shape of liquid that is totally different object (in meaning of topology) from ...

How do i create this smoothie texture for mantaflow liquids?

Try something like this. It's just 3 Voronoi Textures (of varying sizes) with their vectors warped slightly by a Noise Texture so they don't create such "uniformly circular" dots. The ...

Mantaflow - slow drip

Does it has to be fluid sim? For dropping water from object like icicles ... probably could be enough two meta balls. One main Mball inside the tip and second as drop with just animated Z loc and ...

why is my liquid simulation baked like this?

You need to activate this single thing in your fluid domain: This will give all those particles mesh around them, you need then adjust your settings to fit in your scene

Why are my liquid particles so HUGE?

If you want to make fluid simulation i would recommend first to watch some beginner tutorials. There are a lot of good tutorials on yt. Also you can just give "quick liquid" to the default ...

How to make Mantaflow spawn less fluid without resizing source?

The System Maximum value in the liquid domain properties can be keyframed, and then no more hose effect or tap water type flow. What it does is instead of filling the mesh with points and then ...

How to do small amounts of fluid?

If you are going to create only a few drops so that it's no problem creating them manually, you could do the following: In my example I took one sphere and made it a Flow object. Although I just want ...

I want to have cold smoke emitting from bottle but can't get the settings right

I think what you want to create is physically fog, not smoke. It's cold condensed water in the air that settles down and in this case, dissolves quickly. To simulate cold gas there are these settings ...

Fluid domain is visible before and after the animation start

It is simply a matter of inserting a keyframe to turn on/off the render camera at appropriate times for your domain. Right-click on the camera icon by your domain and it can be keyframed just like ...

No water is coming out after baking the fluid simulation

no wonder: your smallest resolution unit (pink) is much bigger than your inflow(blue). The water will only flow if the resolution unit is smaller than your inflow and fits totally in it (better ...

Rocket Launch Simulation with Mantaflow looks weird

Smoke simulations are a very complex thing and there are many settings which could yield very different results. So, it's not so easy to answer a question like how to make it look like the real thing? ...

Blender - Quick Liquid - Domain is a glass cube

The quick effect operators only set up an object for a given type of simulation, you have yet to actually do the simulation, aka "bake" it. For a liquid, specifically, baking will deform the ...

How to achieve this water splash animation for any solid object ( suzanne for ex)?

here a simple example to start with: general hint: water simulation should be rendered in cycles - looks 10x better than in eevee.

Problems with Materials on imported mantaflow object

Ok! So I figured it out! It was simply the mesh. I just applied a simple remesh to the object and it worked like a charm!

Fluid simulation particles are offset from the effectors

This little box which you can see in your domain represents the "smallest unit" of your fluid. If it is too big, it cannot "see"/recognize your obstacle. So you could either ...

foam and bubbles particles in mantaflow just look like white points moving around

you have to set render as object and then e.g. choose an icosphere so that it will be rendered. each of your rendered objects need to have a material (maybe change it to a plain red just to see it ...

Is it possible to stick fluid particles to a wall?

It is not possible to do this in mantaflow, no. The simulation lacks any setting on effectors that would make such an interaction possible. The problem is that the stickiness bit is actually a ...

Mantaflow doesn't look like water after baking

Yes, just create a new material and in the Principled BSDF move the Roughness to 0 and Transmission to 1. You might also want to make sure the Base Color is pushed all the way up to white, or you can ...

Why does my fluid have all this colors after baking? I assume it's a density/ velocity map but don't know how to disable it

It actually is visible in render mode but I've figured it out. I had the box "velocity" checked on the domain and that for some reason creates this particle system to tell what you said. ...

Is there a way to fill a cube up with fluid?

Create a cube that is slightly bigger that your domain and give it a Flow Behavior > Geometry. If you want to drop an object into the water, give your object a Fluid > Effector.

It seems that you need more resolution devision when using copy location as without using it. As soon as I increased this, it worked now.
