Liquid acid

[Pim]

I am trying to simulate below picture / animation.
It is a simulation of fluids mixing (often used in light show at pop concerts).

So the main thing is how to 'mix' textures in cinema?
I started using the Proximal shader, but it is very complicated.

I hop someone can help me.

Hi Pim,

Here is a starting point. Explore how different Noise and Seed versions affect the distortion (animated), while the scale is surely a strong influence.

I have set the ramp to match your reference image.

Back in the days when I made stage light shows for bands for many years, I had one of these Oil projectors that created this effect. There was a round double glass chamber, each filled with two tinted oils. After the light warmed the oil, it produced all these psychedelic patterns based on a little motor rotating the unit with the oils, and the patterns changed. When combined randomly with my other nine projectors, it created a nice blend. Why am I talking about stuff from decades ago? Because the two chambers are a key point here, and I have set the Material up in that way, with two sources mixed in the Color Layer.

All the best

Yes, back in the days with those Oil projector light shows, those were the days.
And exactly what I want to do!
I have a close look at your example and get back to you.

Pim

Thank you Pim.

Please let me know if there are any other ideas or directions we should explore.

Enjoy your project

@Dr-Sassi Now I want to add another object, here a sphere, and let the two textures mix.
I see various options to 'mix' the textures:

• animate the transparency of the objects / textures
• use the proximal shader
• feather the object. For example the sphere texture is too sharp
• add transparency in 'areas' of the textures

Here an example of an extra sphere with an vibrate and transparancy in the texture.

What do you think is th best method to 'mix' the textures and could you give an example?

Hi Pim,

My vision for something like that might be completely different than yours. What is your target with that? What do you like to express or achieve? Where is this shown?

Some pointers:

• You can use another Maxon Noise as Mask - source

• Feather or Displacement would be my question

• There is no Proximal Shader in Redshift; this might be more something about Vertex Values.

We will get so into a different theme, and I would think that should be in a new thread. Mixing follow-up questions that move in a different direction can be difficult to follow after a while, especially if the initial idea or question is mixed in from time to time.

Besides, perhaps explore Liquids now; when you asked the first question, I was not allowed to talk about it, but that would be the next level from my point of view

I want to create those 'old fashion lighth shows' for a music video, initially.
And perhaps later on for the live shows.

I am not sure with what you by 'a new theme'., my main theme is how to 'mix' textures?

Liquids looks great, but I did not find yet, how to mix texture using Liquids.
I know Houdine is capable of doing this, so I guess Liquids will be able to do the same.
Could you make me an example?

I will explore Liquids and your other options (noise as mask, feather or displacement and Vertex values) in more detail.

Thank you,
Pim

Hi Pim,

Here is a different way to produce some old light show effects, perhaps a late '70s feel.

I hope they hold some ideas for you.

Beautiful effects!
I will try to combine them using Maxon Noise as Mask.
I will post the results.

Pim

[Dr. Sassi]

Thank you very much for the feedback, Pim!

Here is a (very) quick fluid example. Needs more work. Increase the mesh resolution (segments) for a finer result.

It needs a little bit of time; render it and use the result perhaps as texture.

Enjoy

Please new themes in a new thread. Thanks.

Hi Pim,

Please continue with the new Question in the thread linked above. Thank you.
