[fcelon]

Renderer class

public class ShockwaveRenderer extends EntityRenderer<ShockwaveEntity>{

	public ShockwaveRenderer(EntityRendererManager renderManager)
	{
		super(renderManager);
	}

	@Override
	public ResourceLocation getEntityTexture(@Nonnull ShockwaveEntity entity) 
	{
		return null;
	}
}

Registering renderer

public static void registerEntityModels()
{
	RenderingRegistry.registerEntityRenderingHandler(ModEntities.SHOCKWAVE, ShockwaveRenderer::new);
}

I have registered entity renderer this way in the past and it worked without error. I don't understand what is the problem now.

ModEntities.SHOCKWAVE

This is probably null. Likely because you're calling this code too early.

[poopoodice]

also iirc returning null in

getEntityTexture

is not allowed (will crash)

[fcelon]

Thakns you, ModEntities.SHOCKWAVE was indeed null. And getEntityTexture returning null doesn't seen to crash.
