kensonuken Posted August 23, 2008 Share Posted August 23, 2008 I am trying to make a meteor travel entering into earth atmosphere.. The tip of the meteor will be burning.. so I want to use the Fx tools " Heavy smoke " utility... now i want to get that gradual ramp where I can control it in the composite... I mean in other words when we render volumes how do we assign a gradient to it? if that is in shops please guide me what to do now.. Quote Link to comment Share on other sites More sharing options...
poltergeist Posted August 24, 2008 Share Posted August 24, 2008 To control color of the smoke, you have to edit this Digital Asset: 1) create vop sop to change(create) Cd attributes for particles and assign color from ramp parameter to this attribute, acording to it's age/life. 2) add this vop sop to the smoke_heavy DA (/obj/smoke_heavy/smokerender) after POP network and before Copy node 3) in the Copy node add Cd attribute to be copied to attributes (Attribute tab) 4) edit DA parameters interface: add created ramp parameter to the Look tab This is your goal? Sample HIP in attachment... Enjoy:) smoke_color.hipnc Quote Link to comment Share on other sites More sharing options...
kensonuken Posted August 24, 2008 Author Share Posted August 24, 2008 hey poltergeist it looks kewl but i couldnt find a copy node after pop network. Can you send me the complete file... But actually what I thought is that why dont i multiply Cd with the ramp with age.. but tell me whats your approach and how it can be beneficial ...

poltergeist Posted August 24, 2008 Share Posted August 24, 2008 This is not my approach:) It is simply works like I want, I don't understand what to explain Quote Link to comment Share on other sites More sharing options...
