Sentence pattern transformation

I teach my student "in spite of ving" pattern.

Although it was raining heavily he went out.
In spite of it being raining heavily he went out.

But the student complains that it should be:
In spite of it raining heavily he went out.
He said raining can modify it. Being is not needed.

Is he right?
Please help me teachers.
Thanks a lot.

Thank you teachers.
Let me ask again.
Although it had rained heavily he did not go out.

In spite of it having rained heavily he did not go out.
In spite of it rained heavily he did not go out.

Which one is correct?
Thanks a lot.

The third is incorrect. Grammatically, the first two need a comma after "heavily". However, they don't make sense. They suggest that normally he would go out when it rains but, this time, he didn't.

These make more sense:

Despite the glorious sunshine, he didn't go out.
Despite the heavy rain, he went for a long walk on the beach.
