Scale a Mob on the Code

put this line "ms.translate(0f, 1.5f - scale * 1.5f, 0f);" before the scaling code, where scale is 0.25

I made my model in BlockBench, I cant find where you told me to put. This is my example model, is there any differences?

public class DireWolves extends EntityModel<Entity> {

Ahznb, maybe you should send some of that code to Klemen on the feature request ticket for scaling mobs, as it might help him add it faster :)

actually this is not the most efficient way to scale a mob. Op actually got it right the 1st time by overriding preRenderCallback in the entity's renderer class. thats the simplest way to do it. it was just that back then we didnt know how to use the gl matrix scale functions for 1.15.x. i'm sure Klemen knows the best way to do it, this is basic stuff to him. 

Anyone help me ? :((

put it before the scaling code and use that formula i gave you, like this:

float scale = 0.7f;
ms.push();
ms.translate(0f, 1.5f - scale * 1.5f, 0f);
ms.scale(scale, scale, scale);
...
ms.pop();

then all you need to do is change the scale variable for you entities, the rest is copy paste

I dont know why but it's not working :((

This is what I did : 

        @Override
        public void render(MatrixStack matrixStack, IVertexBuilder buffer, int packedLight, int packedOverlay, float red, float green, float blue,
                float alpha) {
                
            ms.push();
            ms.scale(0.7f, 0.7f, 0.7f);
            ms.translate(0F, 0.65F, 0F);
            
            WolfHead.render(matrixStack, buffer, packedLight, packedOverlay);
            Body.render(matrixStack, buffer, packedLight, packedOverlay);
            Mane.render(matrixStack, buffer, packedLight, packedOverlay);
            Leg1.render(matrixStack, buffer, packedLight, packedOverlay);
            Leg2.render(matrixStack, buffer, packedLight, packedOverlay);
            Leg3.render(matrixStack, buffer, packedLight, packedOverlay);
            Leg4.render(matrixStack, buffer, packedLight, packedOverlay);
            Tail.render(matrixStack, buffer, packedLight, packedOverlay);
            
            ms.pop();
        }
