Hi, I need to add a Hue/Sat, Emission and Mapping node to my alpha image. I tried adding the nodes but it did not look right so I am here to ask how to do it properly. I want to use the mapping node to repeat the alpha. Can someone please post a screenshot of how to do this. Thanks.
Adding hue/sat to alpha doesn’t make any sense. Hue/sat work on the basis of multiple channels. Alpha is a single channel. From the looks of it, they won’t do anything on your color data in that image either, which looks grayscale. I mean, I guess you could use h/s to colorize, but there are other techniques you could use for that; this would be an ideal use of the generally overused color ramp.
To add mapping, add a uv map node (or some other texture coordinate node, whatever you want), run uv map vector to mapping vector input, run mapping vector output to image texture vector input.
To output emission on what you have, just plug texture color into emission (probably, instead of base color.)
On seeing your second post:
-
To tile, change image border type from Clip to Repeat.
-
You don’t have any emission. But to get it “glow” you need to either use compositing tricks, or render in Eevee with Bloom.
-
Your nodes are almost certainly incorrect (mixing by 1.0 is usually a dumb idea) but it’s kind of impossible to say what the best node setup is without having a better idea of what your goal is.
bandages, thanks for the help! It helped me a lot!
