blender tricks

blender tricks

Here is a collection of blender tricks I always forget about

render options

Sampling

noise and sample number

Light paths

from 12 to 4

illumination

limited

fastGI

fast global illumination approximation

light tree

for multiple sources

Simplify

texture limit to set

camera culling

only the objects in view are rendered

bake

the texture once (for procedural texture)

memory

lower tile size

persistent data

turned on

layer

separate collections into layers

output

exr image (faster than jpg)

lights

sun

the most performant

point/area

ok

mesh light

low performance

clean up

Purge data

preferences

Edit -> preferences ->

system

Enable cuda

viewport

subdivision

Save startup file

mesh

Simplify mesh: Edit [tab] -> [m] Subdivide: Edit [tab] -> [right click] Decimate: modifiers -> decimate

duplicate

duplicate -> [shift-d] instance -> [alt-d]

view

Reset orbit rotation: object -> view -> frame selected

apply to multiple objects

Apply properties (keyframes, materials, nodes…) to multiple objects

Link data : [Ctrl-l]

Or edit the field and press [Alt-Ret] to apply to all selected objects

image to video

cd ~/VideoProd/vfx/render/
ffmpeg -y -framerate 24 -i render%04d.jpg -c:v libx264 -r 30 output.mp4
#ffmpeg -y -f image2 -r 5 -i tmp/img%04d.jpg -s 1080x780 -vcodec mjpeg -vcodec libx264 -r 25 out.mp4
mv output.mp4 ..

comfyUI allows to creates ML pipelines to produce useful assets for blender:

• rotoscopy
• Gaussian splats
