Hey there, I was trying to control scale amount non-uniformly in a tile sampler and was noticing that no matter the R or G contribution it kept scaling uniformly. I popped the hood to take a look and noticed the R and G values were getting added together before controlling the tile scale. I took a crack at breaking them apart and found they started to work more closely to what I was expecting. Not positive my math is 100% correct here but now .5 R or G is full influence and 0 or 1 is no influence. Perhaps it would be more intuitive to have 0 be no influence and 1 be full.

Either way let me know what you think.

Thanks!

Substance DesignerSubstance Designer - Discussions - Barrel Warp?
 on: October 12, 2018, 09:09:08 pm 
Curious if there was already a node I'm missing or if anyone has any tips to create a barrel/lens warp node. I want something that pushes the pixels away from each other using a grayscale map as an input.

Any help is much appreciated! Thanks!

Hi all,

I'm having a hard time figuring out how to control a value in the levels node based on a color output from a color solid.

Basically I'm blending a color solid and a noise together then plugging that into the diffuse. What I'd like to have happen is that as the color value increases the levels out low also increases. The intent being that if I push white through, the influence from the noise becomes minimal.

Currently I have the color going into a pixel processor. Inside the pixel processor I am sampling the rgb values then averaging them to get the overall value. Ideally I would just plug this into the levels out low but I can't figure out how to get that to link.

I feel like I'm probably going about this all wrong so any help would be much appreciated!

Thanks!
