Changing a parameter on all textures

I have a bunch of textures, all different in different objects, that I want to change a parameter, the filter size. On all of them it’s set to 1.00 but I want it to be 0.1.

Is there a way to do this in one go or I have to do it one by one and change it manually?

The way to do this is to bundle your material component into a group node and use it in all materials that need it.

Then when a single change is made in the group node level, it applies to all materials.

This assumes you’re using Cycles by the way.

Unfortunately I’m not. I’m still using Blender Render.

Blender renderer also has its own material node system and a texture node system. Node groups are also possible to be created

need more details but might be possible to do with a small script !

may be ask in python forum
and let us know !

happy bl

in the python console, run this command:

for t in D.textures: t.filter_size=0.1

It worked! Thanks a lot! Kiss
