Random color - how to?

[smicha]

Guys,

I am new to blender (coming here from Sketchup and Modo). Could you please help me of how to get random color over instances? There are many great scripts we created on the forum for random textures (with LUA too)...

Hi smicha,

you can use Random color tex as an input for gradient texture to achieve this.

Thanks for that. Question is how did you create these boxes in blender? Array modifier does not work for it.

The boxes are created using particle system in hair mode.

Or using scatter addoon:

It will also work with the emitter particle system. To position objects where you want you can set it to vertex and use a vertex group. I suspect it fails to work with the Array modifier due to some internal difference in the way instancing is created between the two systems?

FYI - If you do want to stick with an Array approach and maybe get a little more control over your duplicated objects, you can use the addon Random Object Array. It is a paid addon but I just tested it with Octane's Random Color Texture node and it does appear to work.

Guys thank you for that. I did some manual work on instanced box and.. it works. After moving from Sketchup and Modo I really like blender. Hope will stick it for good. Thank you again.
