Tree color variation with _TreeInstanceColor not working anymore?

Questions & Answers
1

In a new scene, I create a terrain obj, and I add a tree prefab using the built-in terrain tool. The tree uses the Nature/Tree Creator Leaves and Nature/Tree Creator Bark shaders in its materials. I set the color variation slider to 1 and mass place the trees using the built-in terrain tool.

The trees are placed successfully, but there is no color variation on the trees. I mass place again with the color variation slider set to 0, and the result looks identical.

I checked out the unity doc: Unity - Manual: Trees
with the relevant part about the _TreeInstanceColor property in the table mid-page, and looked at the code for the Tree Creator shaders in this repo: Unity-Built-in-Shaders/DefaultResourcesExtra/Nature/TreeCreator/TreeCreatorLeaves.shader at master · TwoTailsGames/Unity-Built-in-Shaders · GitHub

The _TreeInstanceColor property is present in the shader, and should work, but doesn’t.

I also tried the scripted approach with this code:

var inst = new TreeInstance();
inst.color = new Color32(255, 0, 0, 255); // Trees should be shades of red.

Which should work according to this manual entry: Unity - Scripting API: TreeInstance

The trees are placed as expected, but not taking the color variation into account.

I use Unity 2019.03.0f6, and I had the same problem with all2019.02 releases. Does anyone know what’s going on?

any update on this?

_TreeInstanceColor always receives white color instead of being randomized

You can get a list of all the edges via graph.get_edge_list()
Each source node should have two target nodes, the one with the lower index is evaluated as True, the higher index as False
Colors can be assigned via set_fillcolor()
