Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to mask out part of texture sample?

Heya all, I've been trying to simulate the effect of rain drops flowing down the walls of a building, so far to little effect. This is the current setup: alt text

The idea is simple, take the rain colour, a gradient and the raindrop path, and set the gradient to pan down. Theoretically, the gradient should cause the rain to show over the texture and flow down. So far, it works, but the rain pathways are always visible in a noticeable dark colour and no amount of tinkering has been able to fix it. Does anyone know how I can achieve this effect without the pathways being visible? I'm thinking there must be a way to mask them out but I'm not sure. I'm pretty new to material editing so there's every possibility that I'm approaching this the wrong way! This is the effect that I'm trying to create: https://www.youtube.com/watch?v=6OTB6GhzZgQ

Thank you for reading :)

EDIT: Resolved! Fixed it by multiplying the gradient with the rain paths and plugging that into the alpha, worked a charm!
