Hi,
I am fairly new to TouchDesigner. I am currently working on a project where I want to fade instances over time. I don’t know a better way so I have a value in my table from which i create the instances that counts as an Alpha Value from 0-1. It is being read by the Instances and used in the Phong Material. I followed the Advice in this Blog Post
. But I just can’t figure out why it is working in that example and not in my use case. I tried copying every setting but my instances just disable when the value hits 0 but other than that nothing changes, as if the value is being changed into an int.
I hope it’s understandable what I am trying to achieve. And thanks in advance!
Okay, one day later and i found somewhat of a solution! When I put ageRanged into R,G,B and change the color mode to replace, it does actually go down in Alpha but turns less transparent and black towards 0. Why does this happen?
the Blending Functions on the Phong Material’s Common page might offer some help. Change the Source Color parameter to “Source Alpha” and you should be seeing more expected results.
Transparency is a notoriously complicated issue in TouchDesigner. The length of the wiki article covering transparency might speak to this fact:
