Thinking Particles Color and Density Channels

Obliging User to

Assign Data Channel On “All”

Group is nonsence for heavy Tp

users…



That is just his example. You can specify the channels for individual groups if you like.



The First step in the

implementation should be

Simply to have Tp Group Picker

For Wich groups To apply the

Krakatoa Effect on … this is

the MOst important thing to

access tp…Allowing Multiple

Group Picking is Also

important …



We have a system like this for selecting which TP groups to actually render, but I think you misunderstand. The color and density extraction is not an effect. Krakatoa merely looks for custom channels named Color and Density when extracting particles. This is a workaround since there is no way to access the material information of each individual particle.



except i

dont get why you have to

Hardcode "Density " or Color

as a Data Channel is either a

Float of a Scalar , color

etc… You can Clamp the Color

Value from Krakatoa to only

access Apropriate Data Channel

and with a Small String Imput

field let the user specify

witch Data Channel he wants to

use for X ) Same thing for 0

Data channel hardcoded…



If I understand correctly, you would prefer a mechanism in the Krakatoa GUI to assign a channel number to the Color/Density data. It seems more straightforward and less error-prone to use the channel names. Is there any reason you would want to extract the color of a particle from a channel not named “Color”?
