Re: Controlling edge falloff on a worldspace projected texture
Did you try connecting to a Power node as to control the sharpness of the falloff? Either that, or try a Clamp node and see which one suits your needs better. Forgot to mention, you do this to the Z-Mask nodes before connecting to the Lerp Alpha. -
Re: Controlling edge falloff on a worldspace projected texture
Hmm, in that case, I would most likely either try a Position/Eye Vector node or Fresnel node, I'm not exactly sure how you would be able to limit to the lower edges of the projection. -
Re: Controlling edge falloff on a worldspace projected texture
What I did (for a different purpose) was to basically remap the entire range to a smaller value range (works a bit like levels, I guess). It's a couple more nodes than you have, but it's also [arguably] more predictable to control. Basically it'll take your image and remap 0-1 to Min-1. (The Constant clamp node is 0-1).… -
Re: Controlling edge falloff on a worldspace projected texture
Yeah that's what I ended up doing. That's why I only posted those top 3 nodes in the first screenshot. :P -
Re: Controlling edge falloff on a worldspace projected texture
funky.. you're not actually using the model's normal map to control the deposits. easy to plug that in later anyway. I spent some time last night chasing down a solution.. got a few close things, but nothing that worked exactly right. I have a similar desposit example shader made up, but I was using an IF based threshold… -
Controlling edge falloff on a worldspace projected texture
Basically I am trying to project a texture onto a mesh based on world space.. which works fine. I'm able to add by a negative constant to control how much of the texture is projected onto the up-facing geometry normals, and multiplying by a constant controls how intense the effect is. The problem I'm trying to solve is how…
