Vertex Animation Textures ROP 2.0 Released Feb. 18, 2020, 12:46 p.m.
Hey Mike!
Thanks for the great work to release VAT 2.0!
Initially I was having issue moving stuff from VAT 1.0 to VAT 2.0 in Unity HDRP. (e.g. removing alignment conversion nodes)
So while I was trying to get a complex sim porting over to VAT, I realize that I would need some optimization and went with the gamedev destruction cleanup sop. But soon enough I realized that it produces some differences visually.
Basically it looks like some pieces were stuck with a single sim point.
I went back to check on the original tutorial posted by Paul but the node do required an original static geo, similar to how I setup using transform pieces, which I do not see in the new destruction cleanup sop as it only takes in the sim and bound now.
So just wonder, if you could share more insight on that, and what would be the best approach to make the sim compatible with VAT?
As I was looking through VAT 2.0, please correct me if i'm getting it wrong, these are the attributes required I assume as :
P - Position of each vertices in world space
Pivot - New in VAT 2.0 correct? This is the pivot of each fragment
Orient - each frag rotation in quat
Rest - initial rest position
UV2 - for pos/rot mapping coord

Great! Thanks Mike!
It turns out that my issue was actually caused by enabling the impact data check boxes in the rbd solver, which baked out the wrong pos/rot textures.

Hi all,
Have started to play with VAT and Unity lately with the followings,
Houdini 17.0.459
GameDev Tools 1.110
Unity 2018.3.0f2
It looks like it is working to a certain point, but I am suspecting the vertex_rigid_body_shader from git and/or rotation exporting was having issues.
It appears as if the pivot is wrong.
I have tried the look at the original vertex_animation_examples.unitypackage. But the rigid body fracture part doesn't seems to be having the right resources (missing baked pos/rot textures), while others (fluids etc) appears to be working.
Here I have attached my unity project assets folder and the hip file. Anyone can help to take a look?
Thanks!
