Dag Posted April 6 Share Posted April 6 Hi, I created a geometry light in Karma and I want to use a color ramp for emission color. How can I achive it? The geo should be volcanic lava. Best, D. Quote Link to comment Share on other sites More sharing options...
asczhu Posted April 8 Share Posted April 8 Hi, I would just create a float attribute (i.e. mask) for the geo. Use noise, random, or bounding box, etc. to generate this mask, as long as the result is between 0 and 1 and fit your design. Read out the mask attribute in LOP and feed it to the ramp node to get the color you like. The rest is easy. Cheers, cz Quote Link to comment Share on other sites More sharing options...
