Detailed objects not cutting

I had a project that didn’t cut all of the items … it was a pine cone with branches on top… the pine cone was approx. 4 inchs so not small. The detail view showed a prefect pine cone with branches. The cut depth was .25 in. The branches never cut into the project … what I’m I doing wrong? The object was copied from easle pro pick of objects.
I have no idea how to fix…

Did you check to see if the bit was to big?

I’m new to this whole thing … my two go to bits are 1/8" down spiral and 60-degree v-bit.
I really haven’t explored anything else. Would there be something better then 60-degree v-bit ? Also, I’m mostly cutting into 3/4" fir boards.

Not sure which bit you used but check your preview window and you should be able to see what will be cut.
