I have been using GFX for awhile now and I'm relatively confident with the program, however the Affects Parameters still baffle me. Somethings like branch length are straight forward enough and work as expected but other times there seems to be no logical correlation between the source parameter range and the graph. Using Affects is the most powerful aspect to creating realist plants but I can't get passed to most basic affects.
Example: I'm trying to change the material ID of leaves on Path that has a Distributor for the 'branches' and an other Distributor for the 'tip'. The leaves on 'branches' have mix of different ID's set under the Mesh Builder but I want the tips just to have a single, different ID to represent new growth.
I assume that if you use Path Position, then the 'Source Parameter Range' is 0 to 100% of the path and because I'm 'Affecting' the Leaf Mesh>Material ID then the values on the graph should relate to the ID of the material right? So at 100% on the graph the value is 9, then this should result in a leaf at 100% on the branch should have an ID of 9......not the case
Please help me understand this the parameter range and the way the graph affects it.
Thanks in advance!
(PS I know I could achieve this with vertex colour or a new path, but the purpose is to understand Affects)
