LocalScale and uv
soooo... i have cube with adjusted uv mapping. I need to scale it by script. I change it by transform.localScale. and then custom mapping goes away.
When i apply scale 1st and then custom uv - no changes, its the same. But if i change scale by inspector, everything work as expected.
i check everything, only one way is to change it by "hands".
question is - how to fix it?\what command i have to use to access scale directly?
edit1: Looks like i found where is problem. When i apply localScale (no matter before or after uv editing) uv coordinates, that read by raycast goes to stock values, but actually texture mapping saved perfectly.
its still issue lol. "How to read "right" uv positions after applying localScale?"
I have no idea what you're talking about. The scaling of the transform only affects the attached renderer and how the mesh is drawn. The UV-map of the mesh isn't changed at all. Every vertex of the mesh have it's UV coordinate and they stay the same, no matter what you do with the transform.
What do you mean by custom uv after you scaled the object? Unity can't edit the unwrap unless you've written an UV editor for Unity.
Please try to explain your problem a bit more in detail and maybe provide a screenshot.

Yep, a picture would be easier to understand than "goes crazy".

Are you sure you use a $$anonymous$$eshCollider? The UV coordinates returned by a Raycast are from the collider you hit, not the mesh. Only a $$anonymous$$eshCollider (with the same mesh) would return the correct UVs.
"Only a $$anonymous$$eshCollider (with the same mesh) would return the correct UVs."
good point, i thought about it while coffee brake.
"Only a MeshCollider (with the same mesh) would return the correct UVs." yes, that was right.
so, if you are manage to mess with custom, runtime generated UVs, and if u want to draw on it - make sure that mesh with new UVs applied to mesh collider, or new UVs will disappear when u will use corresponded gameobject's transform.
tyvm everyone, i really appreciate that.
