Gradient along object hair particles (like grass)?












2














I've spent way too many hours on this and I don't know how else to make this work. Perhaps a dozen hours went into getting the coordinates right on a group of grass, only for it to break completely when made into a particle (I thought this would not be an issue since it is generated from the "object" as you can see below). As for the original mesh, there is a special location that I have put my grass (under the ground) because I don't want to use a (useless) tilted object (seems to be the only way to get the particles to stay upright or they end up being on the side). Here's what I'm trying to do:



enter image description here



Here's what I get, though:



enter image description here



Any help is greatly appreciated. Btw, I'm trying to do this (with the translucent-like effect):

          A couple problems arise from using the Object coordinates. I would use Vertex Colors:



          In Weight Paint mode, use the Weight Gradient tool under Weight Tools in the T sidebar to create a weight gradient along your grass blade. Use the weight painting tools to adjust as needed:



          enter image description here



          Next, enable the Tissue add-on in the Add-ons panel of the user preferences:



          enter image description here



          Now, in Vertex Paint mode, use the Vertex Color from Vertex Group tool in the Tissue Tools panel of the T sidebar to convert the weight into a vertex group:



          enter image description here



          Last, use an Attribute node to get the gradient from the vertex color:



          enter image description here



          Result as a particle:



          enter image description here

Apolo y la Nueve Musas En la mitología griega, las musas (en griego antiguo μοῦσαι « mousai» ) son, según los escritores más antiguos, las divinidades inspiradoras de las Artes: cada una de ellas está relacionada con ramas artísticas y del conocimiento. Son hijas de Zeus y de Mnemósine, compañeras del séquito de Apolo, dios olímpico de la música y patrón de las bellas artes, quien tuvo romances con cada una de ellas, dejando descendientes. Bajaban a la tierra a susurrar ideas e inspirar a aquellos mortales que las invocaran. En la época más arcaica eran las ninfas inspiradoras de las fuentes, en las cuales eran adoradas. Finalmente, alrededor de los siglos VIII-VII a. C. [ 1 ] ​ prevaleció en todo el territorio de la Hélade la adoración de las nueve Musas, que son Calíope, Clío, Erato, Euterpe, Melpómene, Polimnia, Talía, Terpsícore y Urania. El culto a las musas era originalmente de Tracia y Beocia, y fueron de vital impo...
