Blender textures being re-used

[Rhodizites (It Reads)]

I know this isn’t really related to roblox studio, but i am trying to make an asset to put in roblox studio.
So anyway, when i draw on the texture, only 1 line should appear, on the door’s handle.
but instead, 2 lines appear.
one on the doors handle, and one on the doors top.
heres an image:

anyway, how can i fix this? it will help me alot.

random bug report because why not

[Hazelfluff]

Its uv map is in the same place. did you duplicate the same model? It would have the same UV map and texture. Since the texture is shared, any edits to the texture will appear on everything that shares the texture.

[Rhodizites (It Reads)]

i made a new block, no?
what else could cause this

[Hazelfluff]

does it share the same material?

[Rhodizites (It Reads)]

yes!
what can i do to fix this?

[Hazelfluff]

undo the red and duplicate the material (make a single-user copy)

[Rhodizites (It Reads)]

where the hell is that 9

[Hazelfluff]

ah- it’s just 9 on mine because I have 9 meshes using the same material. If it’s not there then there are no meshes using that material

try selecting another one from the dropdown menu

[Rhodizites (It Reads)]

oh…
im new to blender, how do i use this material?
i was using a texture.

[Hazelfluff]

Do you have no other materials in your dropdown menu? (those are just the ones I have, yours will be different)

[Rhodizites (It Reads)]

i have absolutely no other materials. i am modeling just one thing, so why would i make 2!?

[Hazelfluff]

Well uhh… oh umm

is the second part separate?

(when you sect one part does the other get selected as well?)

[Rhodizites (It Reads)]

???
uhh
i dont understand
i said im new to blender so…

[Hazelfluff]

[Rhodizites (It Reads)]

oh, they arent separate
they are all connected

[Hazelfluff]

ah then since the two parts are actually one part, it will have the same material.

(I will help you more I just need to check how roblox handles multiple textures on one mesh hold on)

The new block’s UV’s overlap the door’s UV’s. You’d need to unwrap the handle, and place it elsewhere on the UV map. Here’s a guide.

UV-unwrapping for beginners

Textures are 2 dimensional images. Meshes are 3 dimensional objects. When applying a texture to a mesh, we have to reconcile this dimensional gap. We do that by mapping the 3d mesh to a 2d image. This map, we then use to instruct the texture as to how it should apply itself onto the model. Cube primitive This is called a UV-map. They’re quite important. As we’re essentially ‘unfolding’ the 3d model to become 2d (think of how you could unfold a cube, this is what it’d look like: [f7cf7b2bb82f5…

Another problem I see is that you’re using the original UV unwrapping, which was a cube. You don’t have a cube anymore. You stretched the model, but not the UV map, which means you’ll have warped textures.

[Rhodizites (It Reads)]

i don’t understand. can you explain better?

[ExercitusMortem (Exercitus)]

Read the guide I sent you. That’ll explain it to you. Right now, the UV map of both objects are overlapping, which means the lines will replicated to both objects respectively.

i read it.
makes no sense to me
im new to blender, remember?
i just started yesterday
