I have been using Blender for a while now and i think it’s a fantastic piece of software that just keeps getting better and better. My goal is to be able to make some tutorials especially directed to Renoise users, different techniques to make animations react to your music without too much effort.
First i will try to make something similar to this:
Does any of you have a request to what they want me to make as a tutorial?
A banging cat perhaps? Or a spacship in outer space? Logo animations? Abstract animations?
I don’t know about any way to use MIDI from Renoise to use in Blender, but i will look into it as that seems pretty handy.
The technique i use is simply to render the stems i want to animate and use the audio curve to control just about anything in Blender. By switching out the instruments before you bounce the tracks, with a single cycle wave you can use a AHDSR to get some control of the animations and avoid uneven spikes in amplitude.
That sounds doable, some fractal-ish color stars perhaps and maybe some liquid simulations…i think i should be able to make a simulation of liquid swirling down a drain. Radially symmetric patterns should be quite easy. There are also an addon that makes gears, could be nice for some mechanical animations.
For the video above i used the Eevee renderer which is way faster, but it can’t do as realistic shadows or raytracing like cycles. Using Cycles i’d say you need at least 30 seconds of render time per frame all depending on how complex the scene is. Without a decent GPU it will probably take a lot longer.
Do you want me to focus on Eevee renders or Cycles? Cycles is a lot easier to make things look great, but stylized stuff like the example above could work well using Eevee.
I don’t know all that much how MIDI works, but i think it would be a bit tricky to use to animate things in Blender. You could use volume pots or pitch wheel to move things around, but if you just hit a key it will only send one specific code value while at least most Blender animations needs two or more values to interpolate between.
There aren’t any on/off operations that i can think of in Blender that is useful for animations. I think it would be fairly easy to make a script that takes the single value and turns it into a curve that you could use to animate stuff, but i don’t know much about scripting so i can’t really say.
I might be wrong though, i haven’t put much effort into figuring out how it works.
Fractals are possible in Blender, actually you can make fractals in 2D, 3D and even 4D, but that is quite complicated and i would only be able to copy someone elses tutorials if i was going to try this and i don’t see the point in doing that. There are plenty of fractal tutorials on youtube, but i would think that you probably need a basic knowledge of how blender works before you dive into that.
I think there are some addons that creates fractals in blender, but i haven’t looked into those.
I suggest looking into the free software Mandelbulb 3D if you want to make fractal animations as that is an app that is specifically designed for making all kinds of fractals in 3D space. It’s a great app imo and can make some very stunning images and animations if you put some effort into it. Not the best GUI, but it gets the job done. You can actually also use it to create a fractal 3D object that can be used in Blender, but it has its limits as it gets very large and resource intensive with high detailed fractals and you can never make a mesh object that is a proper fractal with endless patterns. It only captures a fraction of a 3D fractal and turns it into a mesh object.
Here is an image i made in Blender and the rock formation thingy in the background was created in Mandelbulb 3D:
Anyhow i don’t want to make very complicated stuff, i want to keep it fairly easy so that you don’t have to be a math genious to understand what’s going on. Tricks to make some fancy imagery without too much effort.
