[1.12.2] Setting model parts as children of other model parts without resizing them

[nil]

Is it possible to add a model part to another model parts child list while keeping its custom scale?

If not is there another way to make this part turn in sync with the other part?

 

[salvestrom]

My own experience of this, attempting to create babies with enlarged heads for my custom entities, was that I could call poster render method to "connect" the head to the body without making it a child. It would move correctly as if a child model box, but the animation for the scaled box would also be scaled up so the head would animate in an exaggerated fashion compared to the rest of the body and therefore not be completely in sync. It occurred to me to try scaling the animation, but I never actually tried it.

do you mean setting the model parts rotationPoints and rotationAngles to the parent parts?

I think you can create the part with size values multiplied by (child's custom scale / parent's scale), and then add that part as a child. I haven't done much with entity rendering, though, so keep that in mind.

            GlStateManager.pushMatrix();
            
            GlStateManager.scale(0.75F, 0.75F, 0.75F);
            GlStateManager.translate(0, 16.0F * scale, 3 * scale);

            this.lowerbody.postRender(0.0625F);
            this.upperbody.postRender(0.0625F);
            this.neck.postRender(0.0625F);

            this.head1.render(scale);

            GlStateManager.popMatrix();
            GlStateManager.pushMatrix();
            GlStateManager.scalef(0.5F, 0.5F, 0.5F);
            GlStateManager.translatef(0.0F, 24.0F * scale, 0.0F);
            this.lowerbody.render(scale); 
            GlStateManager.popMatrix(); 

The above was being done in the render method of the model class. Note that neck is a child of upperbody which is a child of lower body, but head1 is not a child of the neck.

Although the head will move as the body rotates, this failed because the animations are scaled up with the size of the head, so the head will move in an exaggerated fashion due to things like breathing animations.

Both things actually work:

 

Apparently postrendering a part makes the part rendered afterwards "connected" like in salvestroms example, however i'm not having any issues like this:

Also you can do this:

By calling addChild in the render method however it still rescales the part.
