[question & feature request] Does this CTM mod support the old optifine-CTM format for block overlays

[Lothrazar]

I was going through some ancient minecraft instances and i found a bunch of CTM resource packs that cause block overlays, see screenshot.

This optifine-CTM format of overlay let you use the properties file to add block overlays. Here is a stripped down sample pack that gives this dirt overlay feature if optifine is present. it uses a /assets/minecraft/optifine/ctm/dirt/ path with numbered images and then a dirt.properties with contents like this:

method=overlay
tiles=0-16
connect=block
connectBlocks=dirt
layer=cutout

Please download and see the attached resource pack zip file below

Out of the box when this attached resoruce pack is used with ConnectedTexturesMod , the mod support this and the overlay doesnt show and with optifine it does

so my Question: is there a feature of the mod to suport this type of thing? is there a way to edit the attached resource pack to make these overlays work with the CTM mod without optifine?

Or is it no and the mod does not support overlays.

If its not supported, can you please look into adding this as a feature? Even if i have to edit the pack (for example, one folder in the zip is named optifine) i would love this feature.
