Is there any way to alter the values in this shader via my shuriken system, or do I need to switch to vfx graph?
the Particle system can not make a shader, nor change it… that is not its role/it is not constructed to be capable of that.
what you do is construct a shader with all the mechanics/operations you need, and expose the variables/operations to shuriken through custom vertex streaming.
the particle system has 2 custom data sections; 4 parameters each
for node based authoring Amplify and shader graph the process to expose the properties can be found in videos and forums
thanks thats what i meant, i was prob unlcear! Thanks again!
