I'm following the tutorial below. When I get to the 15:30 - 16min area I run into issues. I have a network that imports and obj, adds points and does a UV projection. I have another network that uses a grid and animates it. It's just a simple animation translating the grid plane along the Z axis. I key framed the grid to move forward and then back. Once the animation starts the network with the obj import shows all nodes with an error each one referencing the node its connected to as basically failed. The import node shows that it cannot find the obj. This issue goes away once i move the slider back to frame 0.

Any help would be appreciated. Thanks!

I think you are mis-using $F.

You have…
MaleBaseMesh_SubD${F}…

What you need is…
MaleBaseMesh_SubD_$F4…

Of course you must name your baked output the same as well. You can optionally add a zero prefix to file names by following the $F with an integer. For example my_obj_$F3.bgeo would write my_obj_000.bgeo.

Try a simple name and a new bake.

Thanks Man! Strange, the file name is
MaleBaseMesh_SubD1_ArmsDown.OBJ

But Houdini is changing Subd1 to SubD${F} like below
MaleBaseMesh_SubD${F}_ArmsDown.OBJ

I changed the file name to the below by removing the 1 after SubD
MaleBaseMesh_SubD_ArmsDown.OBJ

Now Houdini reads the file without adding ${F}
MaleBaseMesh_SubD_ArmsDown.OBJ

Is this a bug?
