Tone mapping

By default, Blender render with Filmic View Transform tonemap. It can be a problem when doing compositing. Better choose Standart ViewTransform instead of Filmic then add a Tonemap node in compositing. Same result, no compositing problems.

Drivers expressions

 

limited value

whaterver le var value is, it stop at 0 if less and 1 if more:

min(max(var, 0),1) 

 

frame

current frame value with sinusoidale loop

sin(frame*0.1)

 

tesselate

 cool way to obtain tesselation:

subdivide the mesh for a good vertesx density.

add vgroup by selecting all the vertex or vertex painting

use decimate modifier with vgroup

Avoid Mantaflow numerous bugs

Following this tutorial : https://www.youtube.com/watch?v=29yfS-icS3M 

I faced Mantaflow bugs (ubuntu20/blender 2.83.9):

Fluid/Flow/inflow/  intial velocity have to be very high (20 in my scene, 1 in the tutorial)

Fluid/Domain/Cache/Type modular break render randomly: use Final always

Fluid/Domain/Adaptive Domain can randomly break at domain border : no solution for now

Material loose major voxels packs at render: It seam related to use of ColorRamp for smoke density

3x3 Mosaic Node Group

Mosaïc node group  generate a 3x3 color grid on UV (if you map it on a plane, it will fill it). Usefull for lowpoly shading all in one shader.

>download the scene

Reset UV. Select wanted faces and move them on the color location based on the 3x3 grid.
