Issue description

Issue: Created a custom mob model in Qubble, exported it as a .JAVA file, imported it into MCreator. Spawned a mob: mob was invisible, but a shadow appeared. Upon attacking the shadow, the mob appears briefly during the damage animation, then disappears again.

I've included the code for the mob entity in the blockquote below.

Issue comments

The issue is most likely caused by this part of the custom model:

@Override
		public void render(Entity entity, float limbSwing, float limbSwingAmount, float ageInTicks, float rotationYaw, float rotationPitch,
				float scale) {
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.Body.render(scale);
			GlStateManager.disableBlend();
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.LLeg.render(scale);
			GlStateManager.disableBlend();
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.RLeg.render(scale);
			GlStateManager.disableBlend();
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.RArm.render(scale);
			GlStateManager.disableBlend();
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.LArm.render(scale);
			GlStateManager.disableBlend();
			GlStateManager.enableBlend();
			GlStateManager.blendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
			GlStateManager.color(1.0F, 1.0F, 1.0F, 0.0F);
			this.Head.render(scale);
			GlStateManager.disableBlend();
		}

I have not seen a code like this in this part of the model yet. This is most likely a specific of the Modeler you use and does not seem to work. Try to remove all GlStateMapper related methods and try importing the model again. Or use another modeler such as BlockBench or Cubik if this does not work.

Got it, so the problem appears to be in the modeling program, and not in MCreator itself.
