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"

Waterfall Particle is not effected by point light from distance, only up close


Im stumble into a quite newbie problem, I'm trying to recreate a large scene that involve multiple huge waterfall from the distance, however it's a dark scene and the waterfall suppose to be illuminated, I tried to use Point Light to lit them up but at a certain distance the particle appear to be completely unaffected by the point light. They only lit up when I'm literally next to them. it might be an ineffective approach to make the waterfall glows, but I don't know how to make a particle system glow/emission lights. The Waterfall I'm using is P_VistaWaterfall_Distant / from learning asset from FPS demo, I believe. Close far and it not even that far, i need them to glow from like 30 time that distance. is there any way to make the waterfall it self glows? It more preferable then point light because it cause everything else around it to be lit bright too much when I only intend for the waterfall to be lit. Any help is greatly appreciated, thank you so much in advance!

Hi there,

Might have some things you can try. With your waterfall particle - find the material you are using for it - open that material up - set it to unlit mode then drag the base colour into emissive - this will make it glow without need for lights.

If this doesn't work - set the waterfall to movable and the light and see if this helps, but ideally you want to try and make the particle glow.

Let me know how you got on.
