[Feature request] custom textures for every color of a CEM bed

[Maluscat]

Hey,
In the last few days, I have transferred my bed model from 1.11- to OptiFine's CEM system so that it can be used in 1.12+ again.
I think it looks kinda cool:

Sadly, custom bed models can only have one fixed texture for its color, and having no colored beds is a huge drawback for most people. As you know, as it's an entity, resource packs can't control anything except the texture by default, so it would be amazing if you added a system to apply color to CEM beds again!

I'm thinking of something a bit like the custom GUI system, here is my proposal:

---

In optifine/cem, there's a file e.g. called "cem_bed_colors.property". The file contains properties of what texture is applied to what color of the bed, for example like this:

entity=bed
property=color
red=bed_red
blue=bed_blue
cyan=bed_cyan
...

Where bed, bed_red, bed_blue, etc. are .png files in the same folder of the .properties file or in subfolders when specified. I also thought that just throwing colors in the file is maybe a bit too specific, so I added a property trait to define what is being customized (But you can decide best on how the structure should look).
In the actual CEM model, one will define something like a property or properties property, in which a .property file is specified. This is then read and applied to the model part!
Example:

"texture": "bed",
"textureSize": [16, 16],
"property": "cem_bed_colors",
"boxes": [
   ...
]

A "texture" property still needs to be specified - it functions as the default texture if not all colors are specified in the .properties file and as fallback if the file cannot be read correctly.
I hope this helps a bit!

Cheers,

Actually you can do it, just don't specify the texture path, so it will use the default minecraft path.
Example:

You deserve a price, my man.
Although it's still not as good as having separate configurable textures, I didn't think of the fact that custom entity models will take the Minecraft texture by default, even if it has multiple variants.
You are a genius, thanks so much!

I've actually already finished the new models:

Gonna close the issue, a solution, even if it's not the proposed one, has been found after all

I believe this issue should be reopened. If a user is not using optifine, their bed textures will be entirely warped and distorted.

The only way around that for a resource pack, is by having these changes in a separate addon pack

This is not true, the default UV does not have to be modified in any way.
The texture UV does not fill the whole 64x64 texture, so there is quite a bit unused space which one can use to add custom textures. That is, if one actually needs custom textures: I did in my case because the model is quite different from the default model, but in most cases one should be able to use the default texture

Correctly, I use that method for some custom mob models based on biome or variant, and it doesn't glitch without optifine.
