Here, try this. Trust me, If I could do it, you could! First, import your obj. Second, make it visible in your camera. Third, go to "stack" in the top bar, and click "modify geometries to create a morph target" Then, go to "selections" tab, and click the icon on the far right, the soft selection button. Next, get in close, so you can see the pink dots. Click directly on a pink dot. A group of pink dots should turn purple. You can change the size of your "impact" by adjusting the "fallot" option, under the stack. Then, go to transformers, and click on either scale, or translate. In scaling, you should not simply use the up and down icons. You need to make a bigger impact, so edit the x,y, or z values directly by changing the numbers. I prefer to deal with the "tenth" value, the one after the decimal. In translating, you can simply use the icon. Try this, and I bet it will work.
