Looks like the Trail3D script extends the ImmediateGeometry
class. When I look at the API documentation for it, it seems that ImmediateGeometry
extends the GeometryInstance
class which has a material_override
property on it. I'm pretty sure that if you assign a new SpatialMaterial
to that property, and you set the albedo_texture
property on that material to a new instance of GradientTexture
, then you might be able to get the look you are seeking.
If I can find time to test out the idea myself, I will, but I'm pretty busy these days. I'd encourage you to give it a shot / experiment in the meantime.
Okay I will thanks for the feebback @willnationsdev
I used the gradient texture but it seems to use the first color only it discards every other color @willnationsdev
Well, props to anyone who can figure out why that is. If I get time, maybe I can look into it, but I'm not really sure where to begin with that...
This requires having a UV map on the generated mesh, which is two gradients that are used for texture mapping. (My profile picture is the debug view of a UV-mapped square! =)
Trail3D
does not create a UV map for its generated mesh trail though, and the default UV map is just Vector2.ZERO
, so only the GradientTexture
's top-left corner pixel is sampled. Which is one color.
Generating UVs for ImmediateGeometry
involves setting the UV value of each vertex in the code, it's not particularly difficult.
I might try doing it!
Doing interpolated UV mapping is really not clean with PRIMITIVE_TRIANGLES
(because triangles aren't truly connected to eachother), I have a feeling that Trail3D
could use PRIMITIVE_TRIANGLE_STRIP
(switching to it is easier said than done haha)
Anyway, I got it working. Just gotta make the C# version and we're golden!
Hi Guys I love your godot-next project I just wanted to propose that a gradient coloring scheme should be added to the trail 3D so as to allow something like this:
But in a 3d space but I really don't know if that's possible so am hoping for a feedback
