way to generate flipbook of multiple views? July 26, 2023, 5:54 a.m.

Absolutely ancient thread, but for those who are here and looking for a low tec option...

Setting your scene view to show quad view, creatinig 4 cameras and setting them in each of the new views, then in the flipbook options select "All Viewports" from the render dropdown in the output tab. This will give you four unique views. Then for your usecase just set the render rez and AA to something acceptable.

HDA Expressions event handler Oct. 5, 2022, 9:21 a.m.

Hi All,

Could someone please show me how I would go about using the expression event handler in an HDA.

I assume that you can write a function there that can then be referenced in a parm, that can be called as an expression. I just cant seem to get anything to work. Checked the docs but the section on hda event handler scrips does not have any reference to the expression option.

Many Thanks

How to procedurally reference specific Pivot Points Aug. 25, 2022, 11:48 a.m.

Hey,
I think I know what you mean...
Check out the attached scene file and see if it helps.

The pivot position can be accessed directly with looking up the points position with the point function.
For the rotations you can use dihedral and then convert that quaternion to degrees. Then add them to the transform pivots rotation paramater with the point function.
