Does malt support Object coordinate?

[HSDSZ]

The problem of UV coordinate is the texture is distorted when the shape is changed.
Any way to achieve object coordinate in Malt?

Below is the UV coordinate in malt

[pragma37]

It's not supported, but I'll look into it.
Shouldn't take too much work.

I'm very interested in getting these too. I use them a lot already.
Especially the ability to get the coords of other objects, like if you select it from the Object Dropdown in the Texture Coords node.

[pragma37]

Ooops! Turns out I completely misunderstood this feature.

For some reason I got it mixed with Generated Coordinates. 🤦‍♂️
I actually even implemented the feature, but I was debating whether to publish it since I'm having a hard time figuring under what circumstances it could be useful.

For getting local space coordinates you can just use an inline node with:

transform_position(inverse(MODEL), POSITION)

MODEL is the object matrix, so the inverse converts world space positions to object space positions.

[HSDSZ]

I am not sure I understand your code.
Could you upload a screenshot of the nodes for local space coordinate?

[pragma37]

(This is the Development branch, in Release, you'll have to set up the COMMON_PIXEL_SHADER Output in the old way)

Or if you want to stick to nodes as much as possible:

The matrix inverse is the only function that is not exposed to nodes.
I plan to rework the way arithmetic works in nodes, so it will probably be available at some point.

Neat. Is it possible to get the Object Coords (or Matrix i guess) of a different Object, like can be done in Cyles/Eevee?

[pragma37]

@aVersionOfReality Using drivers. I guess that's what the Blender node uses internally.
Setting up 16 individual drivers sounds like a PITA, but it's probably not too hard to make an operator that automates it.

Ideally, it should be possible to set any matrix property as an object transform.

My English is not good, this is machine translation, please forgive me. After looking through other answers, I know that Malt can reference color data of geometric nodes, and try to find out the methods implemented in EV&Cy to invoke coordinate control textures of other objects, but it is a little troublesome. For specific Settings, you can see pictures. (Now 2023.5, blender version 3.5, Malt version 1.0.0Beta)
