Skybar Posted August 10, 2013 Share Posted August 10, 2013 I am instancing a point light to some particles, but I can't hide the original light without it effecting all the instanced ones as well. The only way it works is if I'm using Full Point Instancing, but that is so incredibly much slower than the Fast option. Is there any way to hide the original one and still use Fast Instancing?

yongbin Posted August 11, 2013 Share Posted August 11, 2013 can it done by fast point instancing? as far as i know, it only can with full point instancing. maybe i am wrong. If you have very large number of particles, this process of course very slow. because illuminance loop should repeat every light. how about using point cloud in shader?

Skybar Posted August 11, 2013 Author Share Posted August 11, 2013 Yeah I suppose you are right, thank you. How would you do it with a point cloud in a shader? Quote Link to comment Share on other sites More sharing options...
yongbin Posted August 13, 2013 Share Posted August 13, 2013 see this, http://ihoudini.blog...n-and-some.html definitely his one is better than mine, but for some unknown reason, I can't reproduce the result well. maybe I have to spend more time to resolve it. so I attach my one too. if you have same problem, see this. pc_light.hipnc Quote Link to comment Share on other sites More sharing options...
