What's the best program to use for graphics design in unity?

I’m not sure if this has been answered or not, I’m new to Unity.

I’ve asked about how to design graphics for unity but I’ve been told Unity isn’t good for that, I’m better off using another program for this.

I’m mostly looking for a free software, but money shouldn’t be a huge issue.

Thanks.

3D Max is the best for making 3D graphics. If you want proof just ask me.
Blender is free, so is gimp.
And antislash posted a free 3D modeling link on the forum just yesterday.

The search function is a great place to check if something has been addressed in the forum here or on answers.

Blender (3d modelling, animating), GIMP (raster art), Inkscape (vector art, used rarely) … Free
Substance Designer ($150)

thats what i use
