#

as vats and the tool itself are experimental please help us by adding bugs and troubles found here

#

~~BUG~~ in tool - Material slots are lost on export FIXED in new tool
~~BUG~~ in tool - the automated exported mesh and the saved export mesh dont match when manualy exported FIXED in new tool but is possible to mess up with incorrect export settings manually

#

Tool improvment - some errors are not overly clear in the reporting of them (refine error message)

#

can we be allowed to export with all modifiers in the futur ?

#

it really depends on the modifer, alot of them actually change how the vertex' are ordered and the VAT tool requires these to be finalised beforehand otherwise the mapping of the ID's will be wrong

Reuploaded for reference... my VAT Validator, works with a minor modification to official Sansar VAT Generator by adding this line here... @property def allowed_modifiers(self): return [ 'ARMATURE', 'CAST', 'CURVE', 'DISPLACE', 'HOOK', 'LAPLACIANDEFORM', 'LATTICE', 'MESH_DEFORM', 'SHRINKWRAP', 'SIMPLE_DEFORM', 'SMOOTH', 'CORRECTIVE_SMOOTH', 'LAPLACIANSMOOTH', 'SURFACE_DEFORM', 'WARP', 'WAVE', 'MESH_SEQUENCE_CACHE', # Add this line ]

#

I may make a release for beta testers in about a week or so....

....nearly close to release VAT Validator blender addon, but need to hammer out why scale and rotation morphs, squishes object... though location works just fine....

Probably you're trying to use local coordinate space instead of scene coordinate space.

...still looking into how rigged characters already animated are prepared for VAT, having you tried that? What's your workflow..... tried converting to shapekeys, but not getting desired results.... noticed fps drops for VAT validator too... still gathering info to add todo list optimizations...

.....prior issues had with morphing, stretching too much was my validator which was fixed.... working with cloth is too easy.... just export as .ABC then re-import to process as VAT.... keep in mind that frames per second drop when previewing with many frames.... a flag doesn't need 250 frames looping, alot less actually, but was testing how far the validator can handle... later will look into it to see if can optimize it to handle higher frames with good fps.... will be checking .mdd soon to see what results i get.... so far looking good....

.ABC export didn't work well with ocean modifier and didn't pass Validation, but .mdd did work... HOWEVER, same undesired results just like rigged characters... messy... also, previewing with validator causes fps to drop....need to see later on if can optimize the validator to handle many frames... need more investigation why rigged characters or the ocean imports messy... maybe could be wrong workflow....

SOLVED: Ocean modifier works fully..... just follow these steps.... Change the Geometry mode — At the top of the Ocean modifier panel, you'll see a Geometry dropdown. By default it's set to "Generate." Change it to "Displace"

#

SOLVED: Rigged characters process perfect, but but if characters are from other pipelines imported to Blender you need Better FBX Addon to get perfect outputs....

#

GREAT NEWS.... finally optimized the VAT Validator, cleaned up to handle so many frames while previewing, validating VAT Maps...no more lagging slowdown.... will test a bit more before making a new release....

...in this test my VAT Validator is previewing this space capsule animation of 500 frames smoothly without any fps drop or lag... behind the scenes am researching a brand new vat tool I may throw in... will make it a surprise.... 😁
