Gradient Mapping in Object Space
BlackhartFilms writes:
In this tutorial we learn how to set up a basic cloth simulation, how to get our wireframe in our Cycles shaders, and techniques for applying gradients in Object Space! This technique can be used for a plethora of other effects, so it’s definitely worth having in your Shader-Artist toolbelt.
Thank you, this looks to be very helpful to my workflow.
Glad to help :)
thank ya kindly sir
Don’t forget that the color ramp has HSL interpolation, much easier for a rainbow effect. ;)
It does, but you lose the granularity of control that you get with the colour ramp. In this case I could set my specific blue level independent of the other colours. And further I wanted to demonstrate this as a more general purpose effect, which can be used for masking other kinds of effects as well, for which I think the colour ramp is more suited and nuanced.
Oh man, I thought at first that you had figured out how to make an actual stress map in Blender! But now that I’ve seen the video, I can see you are just trying to achieve the same visual look. Oh well. Maybe someday someone will make an actual stress map for us to use.
Blender has the stress map for blender render engine. For this kind of anim probably better than use cycles. https://blender.stackexchange.com/questions/2789/image-texture-intensity-on-deformed-mesh/3059#3059
Here is an example of previous link https://blender.stackexchange.com/questions/2789/image-texture-intensity-on-deformed-mesh/3059#3059

Here is great looking addon Tension that generates vertex color to map stretch/squeez and can be rendered with cycles, but I’m not sure you can change gradient. https://blenderartists.org/forum/showthread.php?345542-Addon-Tension-Map
(Take version on last page.)

OK, with “Tension” addon you can also render stress map, just add a colorramp node :)
